Aggressive mode
For complex cases when there are extra elements over the stamp
If normal cleaning leaves pieces of text or lines, enable Aggressive mode. The service will forcibly remove printed letters, numbers, and straight black lines, preserving the stamp impression and signature itself.
When to enable this mode
A lot of text around
The impression is on a filled-out form, and the form elements are on top of the stamp or signature.
Form lines
Horizontal and vertical lines of the form intersect or frame the elements.
Normal cleaning failed
If fragments of text remain after normal cleaning, repeat with full cleaning.
How to enable
Upload and crop
Upload the file and crop only the stamp or signature area.
Enable Aggressive mode
The checkbox is located under the crop preview.
Start processing
Click "Remove background" and download the result.

Do not enable 'just in case'
Aggressive mode is stronger than normal cleaning. For simple, clean impressions, normal cleaning is usually enough. Enable aggressive mode only when there is genuinely a lot of text or lines around.
