PhotoFit / Signature under 20 KB
Resize a signature to the file size a form allows
Photograph or scan your signature on plain white paper, add it below, and set the limit the form asks for. The clean-up option whitens the paper and darkens the ink, which also makes the file smaller.
Drag to move the photo. Pinch, scroll or use the slider to zoom.
The file stays on your device. We aim a little under your limit so it passes whether the portal counts a KB as 1000 or 1024 bytes.
How it works
Add your photo
Choose a picture, drop it on the page or paste it. It opens on your device and is never uploaded.
Set what the form asks for
Pick a preset or type the pixels and the KB limits. Drag to crop, and pinch, scroll or use the slider to zoom.
Download the file
The result is checked against your limits before you download it.
Questions
How do I get a clean signature image?
Sign with a black or dark blue pen on plain white paper, in good light, and photograph it straight on. Turn on the signature clean-up option to even out the paper and darken the ink.
What if the form needs exact pixels?
Choose Exact pixels in the fields, then type the width and height the form asks for. Common signature sizes are 140 × 60 and 256 × 64 pixels, but check your own form.
Is my photo uploaded to a server?
No. PhotoFit resizes your photo inside your browser. The picture never leaves your device, so there is nothing to store or delete.
Why is my file a little under the limit?
Portals disagree on whether a kilobyte is 1000 or 1024 bytes. The tool stays slightly below your maximum and above your minimum so the file passes either way.
What if the form needs a minimum file size?
If a picture compresses below the minimum, the tool adds invisible padding to the JPEG until it reaches the minimum. The picture itself does not change.
Which pictures can I use?
JPG, PNG, WebP, GIF, BMP and AVIF. The result is always a JPEG, the format almost every upload form accepts. For iPhone photos in HEIC, share or save them as JPEG first, or open this page in Safari.
Does it work on a phone?
Yes. Drag with one finger to move the picture and pinch to zoom. The download button stays at the bottom of the screen.
Does it remove location data from my photo?
Yes. The picture is redrawn and saved as a new file, which drops location, camera and date information.
Is it free?
Yes, with no sign-up, watermark or ads. Voluntary donations pay for hosting.
