Resize a signature to an editable preset (default 300×100 px), as JPG or transparent PNG, with an optional KB target.
Pick PNG with a transparent background for a signature that overlays cleanly. Pick JPG for broad form compatibility and a solid background; JPG fills transparency with the background color.
Leave the target blank to resize only. Enter a value to compress toward a size cap; the panel shows whether the result is under or over the target.
The tool resizes to your exact width and height by default. Re-encoding removes EXIF metadata. Print DPI is not embedded; sizes are in pixels.
Signature size and format rules vary by portal and can change. Confirm the required values on the official upload page before submitting.
Signature Resizer scales a scanned or photographed signature to the dimensions an online form expects — 300×100 pixels by default, and fully editable. You can keep a solid background as JPG or export a transparent PNG so the signature sits cleanly on any page.
You can also set an optional KB target. When a target is entered the tool compresses the signature toward that size at the chosen dimensions and reports whether it landed under or over; leave it blank to resize only, without target-KB compression; the result is still re-encoded by the browser.
Signature upload rules differ between portals and can change, so treat the preset as a convenient starting point and confirm the required size and dimensions on the page you are submitting to.
Export a solid-background JPG or a transparent PNG so the signature works on any form or document.
Leave the KB target blank to resize only, or set it to compress the signature toward a size cap and see what was achieved.
Common signature sizes like 300×100, 400×160, and 140×60 are easy to enter, and any custom size works.
Your signature is processed in your browser and is never uploaded to a server.
Resize a signature to the small dimensions and size that registration and application forms request.
Export a transparent PNG to place your signature on letters, PDFs, or templates.
Trim a large scan down to a neat fixed-size signature image.
Resize a signature from a phone, tablet, or computer browser with the file staying local.
No. The Signature Resizer runs entirely in your browser. Your signature image is processed on your device and is never uploaded.
Yes. Choose PNG as the output format and set the background to Transparent. JPG cannot store transparency, so for JPG the background is filled with the color you choose.
Yes, optionally. Enter a target size in KB and the tool compresses the signature toward it at the chosen dimensions, reporting whether it landed under or over. Leave the field blank to only resize.
It depends on the form. 300×100, 400×160, and 140×60 pixels are common, but you should use whatever the specific portal asks for — all values are editable.
Yes by default. It resizes to the width and height you set. If you add a KB target and enable dimension reduction, it may shrink the image to meet the size and will report the smaller dimensions.
