How much smaller will my PDF get?

Scanned documents and image-heavy PDFs often shrink 60–90% on Balanced. Already-optimized or text-only vector PDFs may shrink little — the tool compares sizes and tells you honestly.

Is the text still selectable?

No — compressed pages are images. That is how page-level compression works everywhere. Keep your original if you need selectable text or searchability.

Is there a file size or daily limit?

None from us. The practical limit is your device's memory — most laptops handle multi-hundred-page documents comfortably.

Compress PDF Files Free — No Upload, No Limits, No Watermark

Most "free" PDF compressors cap you at two documents a day, stamp a watermark on the result, or quietly upload your contracts to a processing server. This one re-encodes your PDF entirely inside your browser — pick Light, Balanced, or Strong, and download the smaller file immediately. No sign-up, no task counter, no watermark, and your document never leaves the device.

How it works: bloated PDFs are usually bloated because of huge scanned images or uncompressed page streams. Each page is re-rendered through your browser's own JPEG encoder at a quality you choose and rebuilt into a clean PDF — the same trick commercial tools use, minus the server farm. Document metadata (author, producer app) is dropped along the way.

Honest limits: output pages are images, so text is no longer selectable, and a PDF that is already efficiently encoded may barely shrink — the tool tells you when that happens instead of hiding it. For signing or further editing, use the PDF editor on the original.

Foire Aux Questions

Tout ce que vous devez savoir pour utiliser PDF Compressor en toute sécurité et efficacement.

No. Rendering and re-encoding happen inside your browser tab. You can compress files with your Wi-Fi switched off.
