Is my file uploaded to a server?

No. This tool runs entirely in your browser via WebAssembly — your file never leaves your device. You can verify this in your browser's DevTools Network tab.

Will compression reduce quality?

You choose the level. Screen is smallest; Balanced is recommended; Maximum keeps quality high. We never return a file larger than the original.

Why didn't my file get smaller?

Some PDFs are already optimized. In that case we keep your original rather than inflating it.
