Enhance a Scan or Photo

It lifts contrast, clears background speckle and sharpens faint text, which makes a grey or unevenly lit scan easier to read.

Yes. Cleaning up a scan before OCR usually makes the recognised text more accurate.

Both. Upload a scanned PDF and every page is cleaned and returned as a PDF with the same page sizes. Upload a photo or a JPG, PNG or WebP scan and you get a cleaned image back.

Cleaning a page means redrawing it, so text that was selectable becomes part of the picture. The words are still there to read but can no longer be selected or searched, and you are told when that applies to your file. Your original upload is never changed.

It can help, within limits. Sharpen tightens soft edges and extra contrast darkens faint text, which is often enough to make a phone photo readable. It cannot recover detail the camera never captured, and it does not straighten a crooked page or remove shadows.

Switch on "Pure black & white". Every pixel becomes fully black or fully white, which makes printed text crisp and clean to print. For pages with photos or shading, choose Grayscale instead, which drops the colour but keeps every shade of grey.

Each page is redrawn as a 200 DPI image so it can be cleaned, and those images usually take more space than the original scan. If the size matters, run the result through Compress PDF afterwards.

Yes. Every tool works without paying and without an account. Files can be up to 200 pages and 80 MB, and a run that fails costs you nothing.

No. All tools work without signing in. An account raises your hourly allowance and lets you see what you have processed.

Your file stays on our server only for a short time while it is processed, then it is deleted. It is sent over an encrypted connection. We keep a record that the tool was used, but not the file name or what is in the file.
