What is the Compress PDF tool?
Compress PDF is a tool that reduces the size of a PDF by rebuilding its pages as compressed images, with three levels: light, medium and high. It works inside your browser without uploading any file to a server. After compression the text of the file can no longer be selected and copied.
What does the tool do?
- Compress the file at a light, medium or high level
- Show the size before and after compression and the percentage saved
- Warn if the file did not shrink because it is already compressed
- Keep the page sizes and order

Frequently asked questions
Is the tool free?
Yes, it is free with no sign-up and no limit.
Are my files uploaded to a server?
No. Everything happens inside your browser and your files never reach us.
Is the quality of the file affected?
Yes, according to the chosen level: light has the least effect and high gives the smallest size with some loss of clarity.
Does the text stay selectable and copyable?
No, the pages become compressed images. Keep a copy of the original file if you need to copy the text.
What if the file does not shrink?
A message says so without a download; try a higher level or keep the original file.
Can I process a password-protected file?
No. Remove the protection from the file first and then upload it; you will see a message saying so.
