Resize a signature to exact pixels and KB
Enter the exact width, height, and maximum file size required by a form. The browser centers the complete signature on white and searches for the highest JPEG quality within the limit.
How it works
Choose a signature image
Open a JPG, PNG, or WebP signature up to 10MB from your device.
Set pixels and KB
Use the 140×60 and 20KB defaults or enter the exact width, height, and file-size ceiling required by the destination form.
Verify and download
The browser creates an exact-size white JPEG, shows its measured dimensions and bytes, and downloads it locally.
What stays private here
- The source signature is decoded in this browser tab.
- Canvas fits and encodes the output JPEG entirely on this device.
- No filename, signature pixel, source byte, or output byte is sent to Peelaway.
- The result exists only on this device unless you download or share it.
Questions about this tool
Will the result be exactly 140×60 pixels?
Yes with the defaults. The output canvas is exactly 140×60 pixels. The full signature is centered without stretching, and white padding fills any unused space.
Will the signature be 20KB or less?
The download appears only after the browser creates a JPEG at or below the selected ceiling. Its exact measured dimensions and file size are shown before download.
Is the signature uploaded or stored?
No. Decoding, fitting, JPEG encoding, verification, preview, and download happen in this browser tab. Peelaway receives no filename, signature pixels, source bytes, or output bytes.
Does this guarantee that a form will accept the file?
No. It verifies the pixel dimensions, JPEG format, and byte ceiling you select. Recheck the destination's current rules for DPI, color, ink, background, and any minimum-size requirement.
