How to compress a PDF to 100 KB

  1. Step 1

    Choose the PDF you want to shrink. It is opened in this tab, not uploaded.

  2. Step 2

    Keep the 100 KB target, or pick another size or level.

  3. Step 3

    Press Compress PDF and download a file of 100 KB or less.

Images are resampled to the size the page draws them and re-encoded step by step until the file is 100 KB or less. Text, links and form fields are not touched, so text stays sharp and selectable. Processing never leaves this tab.

Frequently asked questions

How do I compress a PDF to 100 KB?

Drop your PDF on this page. The target is already 100 KB, so press Compress PDF and download the result. You can change the target or the level before you start.

Will the text still be readable at 100 KB?

Yes. Only images are resampled and re-encoded; text, links and form fields are kept as they are, so text stays sharp and selectable at any size.

Is my PDF uploaded anywhere?

No. The PDF is read and rewritten inside this browser tab. Nothing is sent to a server, and the page keeps working offline once it has loaded.

What if my PDF cannot get that small?

The tool steps image quality down until the file fits. If it would have to wreck the images to get there, it stops and gives you the smallest readable version with a note saying the target was not reached.
