Signature background remover not working? Start here
Rough edges usually come from the source photo, the mask strength, or a format that cannot store transparency. Work through these checks before writing to support.
The first AI pass is still loading
The first run may download model files before the progress message moves. Keep the tab open, retry on a stable connection, and try a smaller signature photo if the browser reports a memory problem. Download finished results before refreshing.
The file or batch is rejected
Keep each input below 25 MB and 25 megapixels. A session also has a file and combined-pixel budget, so a few large scans can fill it before the file count does. Remove finished items after downloading and start a smaller group on a phone.
For a document batch, read the batch and ZIP guide to see how the queue handles one image at a time.
The transparent PNG looks white
Set the background to Transparent and export PNG or WebP. JPG cannot carry transparent pixels. Some viewers show empty pixels on white, so place the file over a colored page before deciding it failed. the transparent PNG guide walks through the same check with a document example.
A loop or letter is missing? Compare source and result, lower the removal strength, or open the Erase and Restore brush. Crop ruled paper closer to the signature so fewer lines compete with the ink.
