How it works

Some forms reject files that are too small. This page raises the quality first and, only if that is not enough, adds invisible padding until the file reaches the minimum.

  1. 01

    Set the range

    The default is 20 to 50 KB. Change it in Settings to match your form.

  2. 02

    Select your images

    Small scans, signatures and screenshots are common cases.

  3. 03

    Download

    Each file shows its new size and a tick when it is inside the range.

Is padding safe?

Padding adds a comment block inside the file that image viewers ignore. The picture, its dimensions and its format stay exactly the same, so portals that check the size accept it. The option is labelled under More options and can be turned off.

Questions people ask

Will the image look different?

No. Raising the quality can only make it look better, and padding does not touch the pixels.

Why do forms set a minimum size?

A very small file usually means a very small or very blurry image, so portals use a minimum as a simple quality check.

Are my photos uploaded anywhere?

No. The resizing happens inside your browser, on your device. Our code never uploads your images, and the page works the same way offline once loaded.
