Example and limits

This tool re-saves a PDF in the browser. It is not a scan downsampler and may save little space in an already optimized document. Keep the smaller acceptable copy.

Can it guarantee a PDF below an upload limit?

No. A scan-heavy PDF may need lower-resolution source images or a dedicated PDF optimizer. Re-saving can also affect digital signatures; preserve the signed original.
