FormResizer

FAQ

Is my signature uploaded anywhere?

No. The signature resize happens in your browser with your device's own processor. Once the page has loaded you can even switch off your internet connection and the tool keeps working.

Does it work on a phone, and without internet?

Yes to both. The tool runs in any current mobile browser, so you can photograph a signature and resize it on the same phone. Once the page has loaded, it keeps working with mobile data or Wi-Fi switched off.

Which file type does the tool produce?

A JPG (JPEG) file, which almost every application form accepts. You can start from a JPG, PNG or WebP image. Transparent PNG signatures are placed on a white background.

What size should my signature be?

Use the size printed in your form's notice or upload page. Forms usually give a KB limit, often with both a minimum and a maximum, and sometimes a pixel or cm size. If the form gives only a KB limit, the default 400 × 133 px at 200 DPI is a reasonable starting size.

What is 6 × 2 cm in pixels?

At 300 DPI, 6 × 2 cm is 709 × 236 px; at 200 DPI it is 472 × 157 px. Use it when your form gives the signature size in cm. If the form lists pixels, use those pixels exactly.
