Compress PDF. For free.

Shrink a heavy PDF so it's easy to email and upload — scans and image-heavy files often drop 50-80%. No watermark, no signup, and if it's already optimized we hand back your original, never a bigger file. iLovePDF can't promise that.

How it works

    We compress it

    Ghostscript downsamples images and subsets fonts for a big size cut at good quality.

Common questions

How small will it get?+

It depends on the PDF — scans and image-heavy documents often shrink 50-80%. If a PDF is already optimized, we tell you and hand back the original untouched, so you never end up with a bigger file.

Is my file private?+

Yes. It's uploaded over an encrypted connection, compressed on our own server with no third-party APIs, and the upload and result are deleted within one hour.

Will it ruin the quality?+

We use a balanced "ebook" setting (~150 DPI) that keeps text crisp and images clear on screen and for everyday printing.

Is there a limit?+

No watermark, no signup, and generous file sizes — free to use.

Why isn't this in my browser like your other PDF tools?+

Real compression re-encodes images and fonts, which needs a proper engine (Ghostscript). Merge, split and rotate stay in your browser; compression runs on our private server and is deleted within the hour.
