Straightforward: we’ll now show you how to resize a PDF document to 800KB or even lower than that.

Let’s look at 3 popular reasons to shrink a PDF to just 800KB:

  • Some websites have an file-size limit for uploads (<800KB);
  • Compressed documents are sent faster via email;
  • Smaller files save up space on memory disks.

Regardless of the reason, we know one thing, and we’ll show it to you now: the easiest way to compress a PDF down to 600KB.

How to compress a PDF to 800KB (Or Less)

  1. Select the document that you want to compress;
  2. Adjust the settings for compression, or leave as they are;
  3. Wait about 30 seconds & Download the <800KB PDF.
Resizing a PDF

Well, that was the whole process; your PDF is now smaller. Short process, isn’t it?

Does compressing a PDF hurt it?

No, not at all. Upon compressing a PDF document, nothing happens to it, besides reducing making the file’s size.

To be transparent, here’s what actually happens in the system when compressing your PDF document to 800KB or even less than that:

  • A. Our system looks for repetitive data in your PDF;
  • B. The software only deletes that data if it’s not going to affect the experience using the PDF.

Example: 99% of the uncompressed PDF documents have repetitive data that can be removed. That’s exactly the kind of info that our system targets and removes.

Here is a quick list of the things that remain unchanged when compressing a PDF:

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

What happens after compressing a PDF?

Our system generates a new, identical copy of the initial document. The only new thing is that the duplicated file is now sized at about 800KB.

Regarding your old file, here’s what happens to it after compressing it:

  • The compression tool deletes it (the old file) forever;
  • The new document becomes available in your dashboard, where you can make changes, delete, or share it. You can also privately-share the file!


What do I do after I resize my PDF?

The possibilities are endless, so to speak.

We offer a suite of PDF-editing tools that work to the same level of efficiency, simplicity and speed — you can delete pages, split PDFs, merge PDFs and so much more.
