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.

Perguntas Frequentes

Tudo o que você precisa saber para usar PDF Compressor com segurança e eficiência.

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