You’re probably on this page becauase:

  • You’ve got a large PDF and you can’t really use it;
  • So you need to compress it;
  • Specifically to 30KB;
  • But you haven’t found a way to do it yet.

Well, the last part is false — you’ve just come across the ultimate PDF compressor, as our software can help you shrink a PDF to 30KB.

By the end of this post, you’ll have a 30KB PDF, as our tool is embedded on this very page that you’re on.

No need to go through many steps!

How to compress a PDF to 30KB (or less)

  1. Drag & Drop your PDF below;
  2. Add ‘30KB‘ in the resizing field;
  3. Wait 10 seconds and download the 30KB PDF.

With this tool, you can easily compress a PDF to such a small size. Besides, our tool is extremely versatile, so you can resize a PDF to whatever size you wish.

Example: Type ’30KB’ in the resizing field and our system will make your PDF worth no more than 30KB. Or, type  “45%” and we’ll shrink your PDF by 35% of its size.

Resizing a PDF

Since 30KB is not really a lot, compressing your PDF to this value is going to be very quick. Expect a wait of less than 10 seconds when shrinking the PDF!

Does compressing a PDF damage it?

No. When you compress a PDF, you’re only changing the file’s size, and not the contents of the file. The purpose is to make the file easier to store and send.

To be honest, here’s what actually happens when you upload a PDF in order to compress it with our software:

  • A. We scan your document and check all the coding inside;
  • B. And we only delete the data that is excessive. Though, we do it with care so as to not remove any elements that will hurt the PDF’s user experience.

Case Study: Over 89% of the PDF files that not compressed contain data that repeats itself. We target that data and remove it in order to reduce the file’s size.

For reference, here’s what remains unchanged when compressing a PDF to 30KB:

  • Text;
  • Fonts;
  • Images;
  • Page settings;
  • Colours;
  • Tables.

Can I convert a PDF to 30KB?

Yes, absolutely! At SignHouse, you just have to upload your PDF and type ’30KB’ in the compression field. Followed by that, you have to wait 10 seconds and click one button to download the 30KB PDF.

It’s really that easy to reduce a PDF’s file size to 30KB!


How do I compress a PDF to 25KB?

If you want to compress your PDF anywhere between 20-25KB, go through this process:

  1. Upload the PDF to our file compressor;
  2. Insert the value (e.g. 25kB);
  3. Wait 10 seconds & Download the new file.

What do I do after I resize my PDF?

The possibilities are endless, so to speak.
