Will my files be uploaded?
Everything runs in your browser. The tool does not upload your file, and our server never receives it. You can check this yourself: open F12, watch the Network panel, and from picking the file to getting the result, no request carries the file out. Once this page and the resources it uses have loaded, it keeps working with the network off. Single file limit: 50MB. Verified 2026-09-07.
Compress PDF files locally in your browser — near-lossless in Standard mode, up to 50MB per file.
FAQ
Will compressing PDF make text and images blurry?
We provide smart compression algorithms that significantly reduce file size with virtually no visible loss in quality.
Is there a file size limit? Can I compress PDFs over 50MB?
The cap is 50MB per file, the same on free and Pro. Files over 50MB can't be compressed here yet — split them first with the split tool, then compress. Processing runs locally on your machine, so it isn't throttled by server bandwidth; the faster your computer, the faster it compresses.
