Remove the white background from a signature
Upload a photographed or scanned signature and Quicklio turns bright paper pixels transparent while preserving darker strokes with soft alpha edges. Adjust paper removal strength if the scan has shadows, then recolor the signature if needed.
Useful for documents, forms, and PDFs
The exported PNG keeps transparency, so you can place the signature over a document without a white box. For document work, continue in Quicklio’s Online PDF Editor.
Tips for clean results
Use an evenly lit photo or scan, avoid hard shadows crossing the ink, and keep the threshold as low as possible while still removing the paper.
