FAQ
Is my file uploaded to a server?
No — everything runs locally in your browser via WebAssembly; your file never leaves your device.
How much smaller will my file get?
It depends on the file — Compress recompresses embedded images using lossy JPEG, so image-heavy PDFs shrink the most, while text-only PDFs barely change.
