Frequently asked questions
Why couldn't my PDF reach 500 KB?
Text and vector graphics are already compact. If a file is mostly text with many pages, or has more pages than the target allows, no amount of image compression can reach the size. You can split the file or remove pages first.
Is Compress PDF to 500 KB really free?
Yes. Every tool on this site is free with no sign-up, no watermark and no premium tier. The only limits are technical ones that keep the service fast for everyone.
What happens to my files?
Your files are sent over an encrypted connection, processed in an isolated worker, and deleted automatically within 30 minutes — or immediately when you click “Delete now”. We never share them or use them for training.
Is there a file size limit?
Files up to 100 MB are accepted. This technical limit protects the free service from overload and is the same for everyone.
