FAQ

How much smaller will the file get?
It depends on the content. Scans and presentations with photos lose 50-90% of their size, text documents 5-20%. If there is nothing to compress, you get the original file unchanged.
Will the text stay as text?
Yes. Images and fonts are compressed, but the text is not turned into an image: you can still select, copy and search it.
Why is the first run slower?
On the first compression the browser downloads a 16 MB processing module. After that it is taken from the cache, and compression takes 2-5 seconds.
Is it free and without registration?
Yes. No accounts, no limits on the number of files and no watermarks on the result. There is one limit: browser memory; on a regular laptop that means files up to 200-300 MB.
Where does my file go?
Nowhere. The page loads a processing module into the browser, and from then on it runs on your device. The file is not sent to a server; nobody sees it or stores it. You can turn off the internet after opening the page and the tool will keep working.
