How it works / no cloud

A conversion engine, not an upload form.

filetity opens your PDF in browser memory, finds the JPEG images inside it, and re-encodes each one at the quality you choose using the browser's own image codec. Text, fonts and vector drawing are copied across untouched. The size shown on the page is the finished file, not a projection, and it is the file that downloads. There is no account, queue, watermark, or remote server in the path.

Straight answers

No accordion. Nothing hidden.

Is it free?
Yes, with no watermark and no page limit.
Does it need an account?
No. There is no account system.
Is my file processed on my device?
Yes. The file is read by your browser and never uploaded. There is no server to send it to.
What formats are supported?
PDF in, PDF out. One file at a time.
What are the limits?
No page limit. Only JPEG images inside the PDF are re-encoded; a PDF with no images is refused rather than handed back no smaller. Very large scans are limited by the memory your device gives the browser.
Does it work on mobile?
Yes, on any modern mobile browser. Large files are limited by the memory the phone gives the browser.
Does it work offline?
Yes, once the page has loaded. The tool keeps working with no network connection.
Why does it say there is nothing to compress?
Because the PDF has no images in it. This tool shrinks a file by re-encoding the pictures inside, so a text-only PDF has nothing for it to work on. It says so rather than handing you back a file that is no smaller, or larger.
How much smaller will my PDF get?
It depends entirely on the file, which is why the page shows you the real result before you download it. A 938 KB scan of two photo pages came out at 354 KB, 62% smaller, at the default quality (measured in Chrome, 2026-08-26). A PDF that is mostly text will barely move, and you will be told so.
Will the text go blurry?
No. Text, fonts and vector drawing are copied across untouched, so they stay sharp at any zoom. Only the embedded photos and scans are re-encoded, and the quality slider decides how hard.
Can it compress a password-protected PDF?
No. It refuses an encrypted file rather than producing a damaged one. Remove the password first, then compress.
