  3. Optional: tick Black & white for the smallest scans.

FAQ

How do I compress a PDF to under 200 KB?

Choose "Under a size limit", click 200 KB and press Compress. If a file has many pages, Black & white helps reach the limit.

Will the text stay sharp?

Recommended keeps text readable for most documents. If the file is already optimized, Dora PDF keeps the original instead of making it worse.

Is there a file size limit?

No fixed limit; very large files (over 100 MB) depend on your computer memory. Split them first if needed.

Is it safe for confidential documents?

Yes. Compression runs in your browser; the PDF is never uploaded.
