PDF Background Eraser
Quickly wipe out stains, smudges, and stray marks from your PDF — plus a one-click full-page clean.
Not Every Mark Needs a Full Page Cleanup
Most background-cleanup tools only know one trick: scrub the entire page and hope it works. But a lot of the time, a document is otherwise fine — it’s just one coffee ring, one smudged stamp, or one stray pen mark that’s ruining an otherwise clean scan. PDF Background Eraser handles both situations. Run a quick full-page pass when the whole background needs whitening, or switch to Spot Erase and click directly on the exact mark you want gone, leaving everything else on the page untouched.
Two Ways to Erase
Quick Erase
A one-click pass that lightens the entire page background, same as a traditional cleanup tool — ideal when the whole scan looks dull or gray.
Spot Erase
Click directly on the page preview to target a single stain, smudge, or accidental mark without touching the rest of the document.
Adjustable Brush
Control exactly how wide each spot-erase click reaches, so small marks don’t accidentally eat into nearby text.
No Software Needed
Runs entirely in your browser tab — no installs, no accounts, and no files sent anywhere.
Common Marks This Fixes
- Coffee rings or water stains on a printed page before scanning
- Smudged rubber stamps or ink blots near a signature
- Accidental pen or pencil marks in a margin
- Small scanner glass smudges that show up as a gray blob
- Old staple or paperclip rust marks in the corner of a page
How to Use It
- Upload your PDF: Drop in the file with the mark or background issue you want fixed.
- Pick your approach: Use Quick Erase for a whole-page clean, or Spot Erase for one exact mark.
- Fine-tune: Adjust strength or brush size until the result looks right.
- Save: Download your corrected PDF immediately.
Good to Know
Spot Erase works best on isolated marks that stand apart from the surrounding text or image. For pages that are uniformly discolored across the whole sheet, Quick Erase will usually get a cleaner result faster than trying to click out every section individually.
Frequently Asked Questions
Can I undo a spot erase if I click the wrong area? Reload the page and start fresh from the original upload — spot edits aren’t saved until you download.
Does Spot Erase work on multi-page documents? It works page by page, so you’ll apply it to whichever page currently needs a fix.
Will this remove printed text by mistake? Spot Erase only affects the exact area you click and the brush radius around it, so keep the brush size small near text-heavy areas.
