Paper & ink cleanup
For ink on paper. Local lighting correction helps reduce camera shadows. Inspect faint and detached strokes.
Check dots and detached strokes: separate marks may be removed.Tips for a better result
Crop close to the paper before choosing the image. Lower cleanup strength if thin strokes disappear. Heavy shadows, patterned paper and blur may need a clearer scan. Document photos and shaded artwork can lose detail.
From handwriting on paper to a reusable signature image
- Choose a clear signature image. Photograph plain paper straight on in even light, with all strokes inside the frame.
- Remove and inspect. Apply removal, then check thin lines and dots. Lower Cleanup strength if faint ink disappears.
- Choose your output. Save transparent PNG or a solid-background JPG. Continue to the resizer when you need specific dimensions or a file-size limit.
Transparent PNG
Place your handwriting in a PDF, Word document or other layout without a white rectangle. The checkerboard in the preview represents transparency; it is not included in the PNG.
White or colour JPG
Choose White JPG when the form asks for handwriting on white paper. Verify the required format, dimensions and file limits in the current instructions. JPG cannot preserve transparency.
Finish your image
Prepare a transparent signature for PDF and Word
Keep the handwriting, choose the right format and inspect the image before adding it to a document.
White signature background
Choose dimensions according to your application instructions. Use Resize for an Exam above to carry your current result across.
Remove a portrait background
Use the portrait model for people, with white, transparent and custom-colour backgrounds.
Questions about signature background removal
How do I keep faint pen strokes?
Choose All ink, lower Cleanup strength and compare the result with View original. Inspect loops, dots and detached strokes. If a stroke is missing or the source is blurry, use a clearer scan or retake the photo in even light.
Can I remove grey lines around blue ink?
Blue / purple ink can help separate coloured handwriting from grey ruling. It also removes black ink, so use All ink for black signatures or mixed-colour writing. Check the whole signature before saving.
Will every paper shadow disappear?
Lighting correction estimates the paper colour around each part of the image. Strong shadows, patterned paper and low contrast can leave residue or lose ink. A clearer photo is the better starting point when the preview cannot preserve the writing.
Does this create a signature or sign a PDF?
This tool cleans the visible handwriting in an existing image. It does not generate a new handwritten signature or sign a document. Download a transparent PNG, then insert it in your document editor.
Should I download PNG or JPG?
Download Transparent PNG to retain a see-through background. JPG uses a solid background: white, or the custom colour you selected. Both downloads retain the source dimensions; the displayed file sizes are measured from the generated files.
Can I choose dimensions and a KB limit?
Choose Resize Photo or Resize for an Exam after processing. Your cleaned image opens in the resizer on a white background. Select the relevant preset or enter your own dimensions and file-size limits, then inspect the final crop and export checks.
Are my images uploaded?
The image-processing steps run in your browser. Continuing to the resizer stores a temporary image copy locally in your browser and removes that copy when the resizer reads it. Image contents and filenames are not included in workflow analytics.
Which files can I open?
Choose a JPG, PNG or WebP up to 25 MB and 20 megapixels. PDF pages must first be saved as image files. The separate resizer accepts images up to 15 MB; a larger cleanup result can still be downloaded.
