Error: “The signature dimensions must be between 100 × 50 and 200 × 200 pixels.”
Width must be 100–200 px and height 50–200 px. Most phone scans are thousands of pixels wide, so they fail. 200×80 px fits the range and keeps a normal signature shape.
Fix it in 3 steps
- Upload your signature in the tool above (photo, scan or screenshot — JPG, PNG or HEIC).
- Adjust the crop. The tool saves exactly 200×80 px within 10–20 KB.
- Download and upload it to the form again. If your notification gives different numbers, change the size and KB in the tool.

How do I fix it?
Use the tool on this page: it is preset to 200×80 px, 10–20 KB, JPG, which passes this check. Upload your file, adjust the crop and download.
Why does the form still reject my file?
Re-check the exact numbers in your notification (width × height and KB). Portals also reject PNG/HEIC files renamed to .jpg — this tool always saves a real JPG. More upload errors explained.
