Frequently asked questions

How much smaller will my PDF get?

Savings depend on content. Image-heavy scans often shrink 40–70%. Text-only PDFs may only drop a few percent.

Is the compression lossless?

Compression uses lossy image downsampling to get meaningful size reductions. Text remains lossless.

Does it run on your servers?

No. Compression is performed locally.

Will fonts still render correctly?

Yes. Embedded fonts are preserved so the PDF displays identically on any device.
