Supported files are processed in this browser instead of being sent to our website server.
How to use Signature Resizer
- Choose a clear signature image.
- Set the required width, height and maximum KB size.
- Choose JPG, PNG or WebP when the receiving portal allows it.
- Click “Resize signature”.
- Confirm the final dimensions and target status before downloading.
What to check before downloading
Trim excess whitespace, fit the signature to 600 x 200px, and compress it toward 20KB or less.
A good signature result should remain readable after whitespace trimming and resizing. Avoid stretching the signature by entering dimensions that are very different from the original aspect ratio unless the receiving portal explicitly requires them.
Format and quality guidance
JPG is usually efficient for photographs. PNG is useful for transparency or sharp graphics but can be larger. WebP can produce compact files when the destination website accepts it. Always verify the format requirement before uploading.

FAQs about Signature Resizer
Does this remove blank space around my signature?
Yes. The signature workflow trims light whitespace around visible ink before fitting the signature into the requested output dimensions.
Can I target both pixels and KB?
Yes. Set the required width, height and maximum KB value, then verify both the dimensions and target status in the result panel.
Are my signature files uploaded to your server?
For this supported tool, processing happens locally in your browser. The selected signature image is not uploaded to our website server for processing.
Why can a portal still reject the signature?
Some portals also enforce format, minimum file size, exact dimensions, ink visibility or other rules. Always compare the output with the current official requirement.
