Free PDF Compressor — No Watermark

There genuinely is not one on the functionality side. Compression consumes your CPU rather than our servers, so the marginal cost of your usage to us is effectively zero. The trade-off you accept is that very large files depend on your device's speed and memory rather than a powerful datacenter machine.

The tool is entirely client-side, so there is no metering infrastructure to switch on. Even in principle, a page you have already loaded keeps working offline — including when you are disconnected from the internet.

As many as you like. There is no counter anywhere in the system because there is no server tracking your usage. Drop in fifty files, come back an hour later and do it again.

Not directly. Encrypted PDFs must have their password removed first, which you can do in Acrobat, Preview on macOS, or by opening the file and re-printing it to PDF with the password supplied. Then compress the unprotected copy here.

Any modern browser with WebAssembly support: Chrome, Edge, Firefox, Safari, Brave, Opera and Arc, on desktop and mobile. Chromium-based desktop browsers are typically the fastest for very large documents.

Yes, in two ways. Pick one of four calibrated presets for a quality-led decision, or switch to Target Size mode and enter an exact figure in KB or MB. Target mode steps through progressively stronger settings and stops at the highest quality that still fits your limit.

Yes. Drop in as many files as you like — they are queued and processed one after another so memory stays under control. Each file gets its own progress bar and download button, plus there is a Download All option.

Yes, and this is usually desirable. Author names, the originating software, revision history, comment threads and XMP blocks are stripped. That reduces file size and removes information you may not want to share — a genuine privacy benefit when sending documents externally.

Text always stays sharp because it remains real vector text rather than an image. Embedded photographs are downsampled and re-encoded, so quality loss scales with how aggressive a preset you choose. Less Compression is visually near-identical to the original.

There is no page-count limit. The practical constraint is memory rather than pages: a 500-page text document compresses easily, while a 500-page high-resolution scan may exhaust memory on a lower-spec machine. Closing other tabs frees up headroom for very large jobs.
