Remove Pen Marks from Scan Seamlessly with AI-Powered Technology in seconds

Remove Pen Marks from Scan is a free online AI tool that removes pen marks, ticks and annotations from scanned pages, for teachers and students who need clean worksheets. Use it when you only have an annotated copy of a page. It is not for removing marks, signatures or corrections from contracts and official records; we do not support that use.

Document scanning is a fundamental part of modern office and archival workflows. But scanned documents often come loaded with pen marks: corrections written over printed text, dates added in ink margins, reviewer comments in the side margins, checkboxes filled in with ballpoint pen, annotation marks, correction fluid with overwritten text, and sometimes multi-generational annotations from different reviewers using different colored pens.

Removing pen marks from a scan is specifically challenging because of the layering involved. The scan captures both the original printed document and everything written on top of it as a single flat image. Traditional editing requires carefully selecting each pen mark area individually, filling it in, and reconstructing whatever printed content might have been underneath the pen strokes — a painstaking manual process.

Our AI diffusion model approaches pen mark removal from scans with a contextual understanding of document structure. The model recognizes that most pen marks on scanned documents are additions to a printed base — they're typically a different ink tone, a different stroke style, and often in locations that follow the annotation conventions of professional documents (margins, correction marks over text, underlines, circle marks).

When you upload a scanned document with pen marks, the AI identifies the pen annotations and separates them from the underlying printed document. Margin notes in ballpoint pen are removed. Correction marks are erased. Dates and signature attempts are cleaned. Underlines and circle marks disappear. The printed document content beneath is reconstructed to its original clean state.

The tool handles blue and black ballpoint pen (the most common), red ink review marks, pencil corrections, felt-tip annotations, and correction fluid with overwriting. Pen mark removal from standard document scans consistently produces clean results. Documents with light-to-moderate pen annotation load (typical office review markup) work best. No Photoshop, no design skills, no signup required.
