Clean Up a Scanned PDF
100% private — runs on your device, never uploaded. Works offline once loaded.
Tidy up a scanned document by brushing over specks, stains, smudges or stray marks on a page. The area is filled from its surroundings on-device, then a clean PDF is rebuilt. Cleaned pages become images; other pages keep their original text.
Tidy up a scanned document
Scanned paperwork rarely comes out spotless — dust on the scanner glass, a coffee stain, a hole-punch shadow, or a stray pen mark ends up baked into the page. This tool lets you brush over those spots on a page and fills them in from the surrounding paper, then rebuilds a tidier PDF. Everything runs on your own device, so the document never leaves your browser.
It works page by page: clean only the pages that need it. A cleaned page is re-embedded as a high-resolution image, while every page you leave alone is copied through untouched, keeping its original selectable text.
What it handles well
Because the area is reconstructed from nearby pixels, it works best where the background is plain paper. Marks sitting directly on top of dense text or a signature are harder to blend cleanly.
- Dust specks and sensor lines from the scanner
- Coffee rings, stains and smudges on the paper
- Hole-punch shadows along a margin
- A stray highlighter or pen mark on a blank area
Keep a text-selectable master
Since cleaned pages become images, keep your original PDF if you still need to select or search the text on those pages. Clean a copy, and only the pages you actually brushed lose their text layer.
Frequently asked questions
Is my PDF uploaded?
No — every step runs in your browser and the file is never sent to a server.
What is this best for?
Scanner artefacts on documents you own — dust specks, stains, smudges, hole-punch shadows, or a stray mark you want blended into the surrounding paper.
Will the text stay selectable?
On pages you clean, usually no — they are re-embedded as images so the mark can be filled. Any page you leave untouched keeps its original, selectable text.
How long does one page take?
Roughly 20–30 seconds per pass, since the cleanup model runs on your own CPU. A single speck needs one pass; marks spread across a page need more. The quality setting caps how many passes a page may use.
