Clean scanned PDFs without deleting pages blindly
FileFit renders low-resolution page previews locally, estimates which pages are nearly blank, and compares page appearance to find likely duplicates. Detection is intentionally conservative and results are only suggestions.
FAQ
Does FileFit delete pages automatically?
No. Suspected pages start unselected. You decide which pages to remove before a new PDF is created.
How are duplicates detected?
The browser compares small visual fingerprints of pages. This can find exact and near-duplicate scans, but it is not a guarantee.
Are my files uploaded?
No upload server is used by this tool. The PDF renderer and PDF library load in your browser, and the selected file is processed locally.

More questions about this tool
Are pages removed automatically?
No. Suggested pages start unselected, and you choose what is removed.
Can two similar forms be different documents?
Yes. Small text differences may be lost in the visual comparison used for screening.
Should I delete every blank page?
No. Some submissions and printed documents intentionally include blank pages.
Remove suspected scan extras without losing a page
Scanning in batches can introduce blank backs of sheets and duplicate pages. Automatic deletion would be risky for documents with faint signatures or nearly identical forms, so the cleaner makes suggestions and leaves removal decisions to you.
The visual comparison is based on rendered page appearance. Similar-looking forms can be mistaken for duplicates even if their filled-in values differ, particularly when text is small.
Step-by-step workflow
- Open a copy of your PDF and analyze with conservative blank/duplicate sensitivity first.
- Inspect the thumbnail and page number of every suggested page. Do not select a page just because it appears on the warning list.
- Tick only pages you have visually confirmed should be removed. Create and download the cleaned PDF.
- Compare the new page count, order and critical stamps/signatures with the original before submitting it elsewhere.
Common problems and what to check
| What you notice | What to check |
|---|---|
| Faint page flagged as blank | Zoom in and check for pale stamps, signatures or handwritten notes. |
| Similar forms flagged as duplicates | Verify names, dates and small filled-in fields; similar page layouts may be intentional. |
| Important page disappeared | Return to the original and rebuild the output with fewer selections. |
Important limitation
The cleaner is a visual screening aid and does not understand document meaning or know which pages a destination requires. Keep the original PDF and review every deletion.
