Sample output — your files never leave your device.
Compression targets embedded images. A PDF that's mostly text is already small, and images stored as Flate/CCITT (common in some scans) aren't recompressed. The biggest wins are on photo- and JPEG-heavy documents.
Text stays selectable and sharp — only embedded images are recompressed. On Balanced or Best quality, pages typically look identical on screen.
Balanced is the right default. Choose Smallest size when you're fighting a hard upload limit, and Best quality when the PDF will be printed or zoomed.
Yes. Unlike server-side compressors, the file is processed in your browser — it never leaves your device, so contracts, statements and IDs stay private.

GenRise Compress PDF shrinks PDF files where their size actually lives: embedded images. It recompresses JPEG images inside the document at your chosen quality and downscales oversized pictures, then re-serializes the file efficiently — so scanned and photo-heavy PDFs can drop dramatically in size while text stays sharp and selectable. Pick Smallest size, Balanced or Best quality depending on how much you need to save. Everything runs in a browser worker, so even confidential documents are never uploaded.
Compress PDF runs entirely in your browser. Anything you enter or upload is processed locally and never sent to a server. There is no account required, no tracking of your content, and no data collection.
