PDFs can be very large. Fortunately, there are easy-to-use applications that can shrink a very large PDF to make it easier to email and share online. Compression Tool

Here are four tools to help you compress and shrink PDFs.

How to make a PDF smaller?

Third-party PDF tools
PDF Browser Tools
Windows PDF Tools
Mac PDF Tools

1. Third-party PDF tools

Adobe Acrobat PDF Optimizer (cross-platform)

If Adobe Acrobat is installed on your computer, there is a tool called “PDF Optimizer”. This tool is one of the best and easiest ways to shrink a PDF document .

To do this, open your PDF in Acrobat. Click Tools> Optimize PDF . A toolbar with a few options appears just above the PDF .

If you click Reduce Size, Acrobat will use the default settings for your file to make it smaller.

If you click on Advanced Optimization, you will have more options to maintain the quality you need. To help with this, in the Advanced Optimization window, click Audit Space Usage, where you can see how much space each element occupies in the file.

PDF Compressor (Windows)

PDF Compressor is a great option for ease of operation and the ability to compress many PDFs at once. Not only can it compress thousands of PDFs at a time, it can also shrink encrypted and protected PDFs .

In addition, this compression is harmless, meaning the quality is maintained despite the smaller size.

4Dots Free PDF Compress (Windows)

This free app lets you compress one or more PDFs in one go. You can also compress all PDFs with just a few mouse clicks, even if the PDFs are encrypted.

When you specify which files you want to compress (drag and drop means drag and drop), select the location where you want the smaller files to be saved. Tap Compress, this tool will do everything.

Free PDF Compress (Windows)

The software is completely free and easy to use. Select the file you want to compress and tap Compress and then save the smaller file.

In addition, you can choose one of 5 compression levels based on the type of file you extract:

Low resolution (72 dpi), perfect for display
Medium resolution (150 dpi) suitable for books
High resolution (300 dpi), suitable for printing
Prepress or pre-printed (300 dpi) suitable for coating, including color preservation
By default, suitable for a wide range of applications

2. PDF Browser Tools

Smallpdf

You don’t even need to have an account to use SmallPDF. Just go to the site, add the file and click Compress PDF. You can then drag your PDF inside the page, place the file on your hard drive, or import the PDF from Google Drive or Dropbox. This file is automatically compressed. Just click the download button to save the new file to your hard drive.

You can compress two files for free per hour. If you want to compress more files, you need to use the Premium version.

The quality of the compressed file is not less than 144dpi. This way most PDFs are small enough to be uploaded or sent by email without any problems. And if you’re worried about security, you should say that files are deleted from the SmallPDF server after one hour.

NeeviaPDF

If you want more control over the quality of compressed PDFs, try DocuPub’s NeeviaPDF (for files less than 10 MB in size).

To make things easier, you can choose from one of the printouts that includes low compression (for higher image quality) to high compression (for lower image quality). There is also an option to exclude specific elements from your PDF . These elements include things like forms, annotations, and page tags that unnecessarily increase file size.

How much of your original PDF elements you want to put aside depends on how much space you want to save.

3. Windows PDF Tools

Finally, Windows 10 includes the print-to-PDF option. However, advanced features such as manipulating the quality and size of a document are not included. In addition, many PDF printers allow you to choose quality and compression settings that can greatly affect the size of your PDFs .

Note that the tools mentioned below need GhostScript to view and manage PDFs .

FreePDF

It’s a classic PDF printer, and that’s why we’ll mention it here, because it lets you build your own compressed profiles. Once installed (remember you need Ghost Script), you’ll see it in the list of your Windows printers.

To reduce the size of a PDF document with FreePDF, open it, press ctrl + P to launch the print conversation, open FreePDF as your printer or printer, click OK and wait for the FreePDF dialog box to appear.

. Here, you can choose from three pre-printed PDF profiles, eBook, High Quality and Medium Quality.

To create a regular PDF profile, click Edit Configuration in the upper right corner, select Profiles and click New, and customize the options in the Profile editor window. You can change the normal quality of your PDF and adjust the default image resolution for PDF images, or add a watermark to your PDFs .

The default average quality profile compresses a scanned 10 MB PDF document to a 1.7 MB PDF file with an acceptable quality loss in quality.

IrfanView

IrfanView is a feature-rich, lightweight image viewer for Windows. The IrfanView comes with a number of plugins that make it a versatile tool, for example to convert images to different file types, add watermarks to photos and batch processing images. It also has the quality of PDF printing, though not in the classical sense.

Before you can view PDFs with IrfanView, you need to install GhostScript. Then, when you try to save your large PDF as a smaller PDF file, you will see a PDF Settings window next to the Save PDF AS… dialog.

In the General section, you probably need to set the Preview of PDF during save operation not needed , so you can quickly select the settings. You can then adjust the compression settings as follows.

In this experiment, we selected medium quality for all types of images that could reduce the size of the scanned 10 MB PDF document to less than 1 MB. The result was blurry, but perfectly legible.

4. Mac PDF Tools

PDF Filter

If you regularly update your Mac OS, you should be able to shrink your PDF without installing new apps. This is a great feature in OS X that many are not aware of.

First, open the PDF in the preview. Usually this happens by double-clicking on the file, but if you have a PDF reader like Adobe Reader, right-click> Open With> Preview . Then, click File> Export , and in the Quartz Filter drop-down box, select Reduce File Size .

PDF Squeezer

Aside from the simple process above, there are not many options for free and popular PDF compression tools for Mac users.

If you want to control the output quality of your compressed PDFs , you might want to download an app like PDF Squeezer, which of course includes fees.

How to shrink PDFs?

This is just the beginning of what you can do with your PDFs . From reading text to images and scanning malware files to converting PDFs to other formats and unlocking encrypted PDFs , you can find the best PDF tool to help you.

It doesn’t matter if you are dealing with interactive PDFs or large ebooks, however, PDFs can be very large. Each of the tools above helps you reduce the size of these PDFs to a manageable level.

iFixit Pro Tech Toolkit Review: The Last Gadget Repair Kit You’ll Ever Need

msrxp — Mon, 19 Nov 2018 20:54:10 +0000

Getting your first toolkit is a rite of passage when you become an adult.

However,

most standard home toolkits don’t come with the kind of specialty pieces you need when you want to repair modern electronics.

For that,

the iFixit Pro Tech Toolkit has virtually every tool you’ll ever need.

Unlike a standard home repair toolkit,

iFixit specializes in kits to repair electronics. The company has an extensive catalog of detailed repair guides for smartphones, tablets, game consoles,

and tons more. Each guide specifies how hard it is to do the repair and what tools you’ll need to do it. Take a look at any given guide,

though–say this one on how to replace an iPhone X battery–and you’ll quickly realize how few of those tools you have.

Fortunately, almost everything you need is in the Pro Tech Toolkit.

What You Get In This Kit

The iFixit Pro Tech Toolkit ($65) isn’t your ordinary toolkit. Since iFixit has spent years tearing down and repairing gadgets,

the company has a pretty solid idea of which specialty tools you need most often.

This particular kit is iFixit’s mid-range model.

It has more tools than the Essential Electronics Toolkit ($20), which in my experience wasn’t quite as robust.

You can also get the Repair Business Toolkit ($240) which, true to its name,

is really more suited for someone who hopes to start a side business repairing electronics.

For your average home electronics repairs, it’s overkill. The Pro Tech Toolkit, however,

is perfect for a home user.

So,

what do you get in this kit that you can’t get anywhere else? Here are just a few of the most important parts:

Tri-Point and Pentalobe screwdriver bits. Modern electronics like the iPhone or Nintendo Switch use special screws with three or five points, as opposed to a standard Philips screws with four points. Even some typical screwdriver kits don’t include these,
so it’s nice that iFixit’s kit has both. And in multiple sizes, to boot. There’s also a SIM card eject bit so if you lose the one that came with your phone, you can use this kit to swap SIM cards.
Specialty and legacy bits. It’s not just modern bits this kit covers. It includes a range of obscure bits, from the gamebit fastener used in old Nintendo consoles like the SNES,
to the oval head bit used in Nespresso coffee machines. It even comes with a magnetic bit you can use to grab tiny screws that you dropped or that are hard to pick up. No matter what gadget you need to take apart,
there’s a good chance that whatever bit you need is in this kit.
A selection of pry tools.

If you need to take apart compact devices like a phone or tablet,
you’ll need more than just screwdrivers. Pry tools are important for separating components that are glued together. There are multiple tweezers and spudgers to pull apart electronic bits. It comes with three plastic opening tools and five plastic opening picks. They’re purposely made of lighter plastic so they should break before you apply so much pressure that you would otherwise break your gadget. If you need a more powerful pry tool, there’s a metal jimmy tool you can use to separate pieces.
A light-duty suction cup. In some cases, you’ll need to pull glass components apart from the components they’re glued to. Pry tools can help but if there’s no place to slide a pry tool in, a suction cup is best. The included suction cup isn’t going to pull dents out of your car, but it’s strong enough for some light repairs.
Anti-static wrist band. Anytime you’re operating on electronics, there’s a risk that static electricity in your body could build up and accidentally fry your gadgets. For that reason,
you should always use an anti-static wrist band when you’re working on electronics. Wear the strap around your wrist, and connect the other end to a large piece of unpainted metal. If you’re opening up a computer, then the case should do.
A magnetic metal sorting tray.

When you’re taking apart electronics, you’re going to end up with a lot of little pieces that can get knocked away or disorganized. This is where magnetic screw trays can come in handy. Conveniently,
the iFixit kit has a metal plate that the screwdriver kit sticks to. When you take the screwdriver case out,
you can place your screws on the plate to keep them organized. When you’re done, stick the case back and it sticks to the magnetic plate and stays in place.

You can read more about the specific tools in more detail at iFixit’s site here. Suffice to say,

if you’re opening up a gadget, there’s a good chance you won’t need anything outside what’s in this kit. The kit as a whole is more expensive than, say, buying a Tri-Point screwdriver if you only need that. However, if you spring for the kit,

it’ll probably be the last time you’ll need to buy tools to work on electronics.

The entire kit comes in a polyester canvas case that folds up and closes with velcro. This is distinctly different from most toolkits that are housed in some form of plastic. The canvas case is less likely to get cracked or broken. Plus, it looks a lot nicer.

This Kit Was All I Needed to Mod My Nintendo Switch

In a previous article,

I talked about the case mod I applied to my Switch. I took apart the console and both Joy-Con controllers and replaced their casings with a sweet, transparent Ice Blue shell. This process was a bit more involved than opening up a desktop PC. Fortunately,

every tool I needed was in the iFixit kit.

For starters, the external portions of the Switch were sealed with Tri-Point screws,

which posed no problem thanks to the bits in the screwdriver kit.

The Joy-Con posed the toughest challenge. On top of the specialized screws,

I had to gently release and unplug several extremely tiny ribbon cables (thanks tweezers),

and I had to gently pry the battery out of its case where it was stuck in with double-sided tape (thanks spudgers).

Oh,

and of course the anti-static wrist band made sure I didn’t fry my favorite console while I was opening it up.

Case modding a Switch isn’t quite as difficult as repairing a cracked iPhone screen or replacing your phone’s battery. Aside from the small amount of double-sided tape,

I didn’t have to do any major adhesive removal like you might need to do on a smartphone repair job.

However, if I did need to, I’d have the tools to do it. I’ve had to buy separate parts and tools over the years to open up gadgets,

but this was the first time I felt like I had everything I needed in one pack.
