Frequently asked questions
- This tool is most effective on scanned or image-based PDFs. If your PDF contains selectable text (not a scan), the text is already sharp — no enhancement needed.
- Maximum 10 MB and 20 pages. For larger files, try splitting the PDF first and process each part separately.
- It may. Processing produces high-quality images per page before recompiling the PDF. The output may be larger than the input.
- Split the PDF into smaller parts first (ilovepdf.com has a free split tool), then process each part here. Alternatively, use the Fix Blurry Image Text tool on individual page screenshots.
