About Compress PDF
Most PDF bloat comes from oversized images. Berlvis Compress PDF rasterizes each page at a target DPI, re-encodes it as JPEG, and rebuilds the PDF, typically cutting size by 60-90%. You pick the trade-off between file size and quality with a single slider.
Frequently asked questions
+Is the Compress PDF tool really free?
Yes. Every tool on Berlvis Tools is free with no signup, no watermark and no daily quota. No signup, no email, no watermark, no file-size cap, no daily quota, Berlvis Tools is 100% free because the heavy lifting happens on your computer, not on a paid server.
+Are my files safe when I use Compress PDF?
100%. Your file is processed entirely inside your browser. Nothing is uploaded, nothing is stored, and nothing leaves your device, that means it's faster, safer and works even when you're offline. You can even disconnect from the internet right after the page loads, the tool will still work.
+Is there a file size limit?
No. Because the work happens in your browser, the only real limit is your device's RAM. We've successfully processed PDFs over 500 MB on a regular laptop.
+Does it work on Mac, Windows, iPhone and Android?
Yes, anywhere with a modern browser (Chrome, Edge, Safari, Firefox, Brave, Arc). Nothing to install.
+How small can it go?
Photo-heavy PDFs usually shrink 70-90%. Text-only PDFs are already tightly packed and may only shrink slightly.
