If you need to resize your PDF document all the way down to 400KB, then you've come into the right place. We'll help you do that in just one click.

You may want to reside your PDF file to 400KB because...

  • A website requires that you upload a document of max. 400KB;
  • You want to send a file via email and it needs to be smaller;
  • You want to save up some space on your device's memory disk.

No matter the reason why you're here, we are going to help you resize PDF documents to 400KB. Let's start compressing!

How to compress a PDF to 400KB

  1. Select your PDF and upload it (or drag & drop the document);
  2. Pick your compression method, or leave the settings as they are;
  3. Wait about 30 seconds and then download the 400KB PDF.

That's it! You've successfully compressed the PDF to just 400KB.

Does compression affect my PDF?

No, compressing is safe. The only thing that happens when compressing a PDF is just reducing the size of the document. Nothing else!

In fact, here's what's actually going un "under the hood" of our system. The compressing software looks for any data that:

  • A. Is repetitive & doesn't serve a purpose;
  • B. Removes it only if it won't affect the usage of the PDF.

Example: In 99% of the cases, uncompressed PDF documents have extra information that needs to be deleted. That's the kind of data that our system looks for and removes in order to get your file down to just 400KB.

Here are the things that remain untouched when compressing:

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

What happens after compressing my PDF?

When your compression is finished, the PDF reducer creates a copy of the original document — that's the compressed to 400KB PDF file.

Regarding your old file (the one uploaded before compression), here's what happens to it:

  • Our system automatically deleted the pre-compression document a few hours after usage;
  • The new, freshly-compressed file is available in your dashboard, where you can edit, delete, share, or privately-share the document.

You are the only one who has access to the documents. Why not also add your electronic signature to the compressed PDF?
