Signature background remover not working? Troubleshooting and support
Most rough results come from the source photo, the tolerance setting, or an export format that cannot store transparency. Work through these checks before contacting support.
The signature is stuck on “processing”
The first AI edit may download model files before it starts. Keep the tab open while the progress message advances. If the download fails, retry on a stable connection and check whether a browser extension blocks the model host. For a memory warning, try a smaller signature photo.
The upload is rejected or the batch stops
Use JPG, PNG, or WebP for a signature photo, keep each file under 25 MB and 25 megapixels, and remember that a session has a combined pixel budget. Remove completed jobs after downloading them before adding another large scan.
For a document batch, the batch and ZIP guide explains the one-at-a-time queue and the files included in the archive.
The downloaded PNG looks white
Confirm that the editor is set to Transparent and that the file extension is PNG or WebP. JPG cannot contain transparent pixels. Some viewers show transparency on white, so place the PNG over a colored page to verify the alpha channel. the transparent PNG guide covers the same check with a document example.
A letter or loop is missing? Compare the source and result, reduce tolerance, or open the erase and restore brush. For ruled paper, crop closer to the signature before processing so the tool has fewer competing lines.
