Stamp and Signature Photo Editor
Change the color, brightness, and contrast of the impression after removing the background
After cleaning a stamp or signature with SigCleaner, you can fine-tune the result in the built-in editor: make the stamp blue or red, darken a pale impression, and enhance contrast and sharpness.
When you need the editor
Change the impression color
The scan turned out gray, but you need a blue or red stamp — choose a ready-made shade or your own color.
Lighten or darken
The impression is too pale or, conversely, too dark — adjust the brightness and contrast.
Fine-tune details
Enhance ink saturation, make the stamp edges sharper, or restore the original look.
How to open the editor
Right after processing
On the main page, when the result is ready, click "Open in photo editor" below the download button.
[step title="From the \"My Files\" section"]
Open My Files, find the desired stamp or signature, and select "Edit" in the file's action menu.
[/step]
Save changes
Click "Save" — overwrite the current file or create a copy with the new settings. You can also download the PNG without saving it to "My Files".
What can be adjusted
Color overlay
Ready-made shades for stamps: blue, red, green, black, graphite. There is a "Custom color" palette for precise matching.
Brightness and contrast
Using the sliders, you can lighten or darken the impression after scanning.
Saturation and intensity
Adjust the color saturation and ink intensity.
Sharpness
Increase the sharpness of the stamp or signature edges if they turned out blurry.
Preview on paper
The button with the sheet icon turns on a white paper background under the impression — this shows how the stamp will look in a document, rather than on a transparent background.
Saving the result
Save to current file
Replaces the original PNG with a new version using your settings. Convenient if you need one final stamp.
Save as duplicate
Creates a new file with the same settings without touching the original. Suitable for multiple color variants of the same stamp.
Undo all changes
Resets the sliders and color to their original state after background removal.
Editor is available for saved files
You can only open the photo editor for results that have already been processed and saved in your account or session. First, perform background removal, then go to the editor.
