Find pages that may need rescanning
FileFit renders each page at a consistent browser resolution and calculates visual signals. It can highlight pages that look unusually blank, dark, light, low-contrast, soft or possibly skewed.
These are heuristic warnings, not a guarantee. Photos, certificates, faint stamps, intentionally blank pages and unusual layouts can trigger warnings. Always review the page preview and the original document yourself.
FAQ
Does the tool OCR my document?
No. It analyzes page appearance, not the meaning of the text.
What does possible skew mean?
The browser sees a pattern consistent with slightly tilted horizontal content. Complex layouts can produce false warnings, so the result is shown only as a review suggestion.
Are my scans uploaded?
No upload server is used by this checker. The PDF renderer runs in your browser.
