How to use the Resize Signature to 50mm x 20mm
- Choose a photo, or drag it onto the drop area. It stays on your device.
- The size is already set to 50 × 20 mm (591 × 236 pixels). You can switch to a custom pixel size if your form asks for something else.
- Drag the crop box over the part of the picture you want to keep. It stays locked to the right shape, so nothing is stretched.
- If the form has a file-size limit, type the maximum in KB. The tool lowers JPG quality until the file fits and shows the real size.
- Press Create, check the preview and the pixel size, then download the file.
About this tool
50 × 20 mm is a 5:2 strip, a size that signature boxes on forms and certificates commonly use. At 300 DPI it is 591 × 236 pixels. The same size is 295 × 118 px at 150 DPI; 591 × 236 px at 300 DPI; 1181 × 472 px at 600 DPI.
A signature photo has the same problem as a passport photo: the box has a fixed shape, and a whole page does not. Crop tightly around the writing, leaving a thin margin, and the signature will fill the box instead of becoming a tiny mark in a lot of white.
Dark ink on white paper in even light gives the cleanest result. If the form asks for a very small file, JPG with a KB limit is the best choice, because PNG cannot be reduced by lowering quality.
Practical uses
- Making a 50 × 20 mm signature image for a form.
- Trimming a signature scan to a tidy 5:2 strip.
- Producing a 591 × 236 px signature file.
Tips for better results
- Write the signature large on plain white paper before photographing.
- Keep the camera straight above the paper to avoid slanted lines.
- Resizing produces the size you choose. It cannot make an organisation accept the file, because forms and offices also set rules for background, head position, file type and file size.
