How to Compress PDFs Online Safely

Pick one or more PDF files

Select documents from your device. You can batch-process multiple PDFs simultaneously.

Choose a compression level

Select a preset like "Lossless" for simple un-optimization fixes, or "Extreme" to aggressively shrink high-res pictures to make your document email-friendly.

Click Compress & Save!

We process the files straight from your RAM, completely skipping standard server-side upload loops. You get an immediate PDF or ZIP download.

Why choose our PDF Compressor?

Privacy Guaranteed

Are you compressing confidential reports or contracts? Other providers keep logs! This tool compresses using only your processor. We never see your files.

Advanced Fallbacks

Is your PDF entirely scanned images? We have a specialized "Scanned" setting that strips the size and retains monochrome reading quality.
