Accessibility

The tools are meant to be usable without a mouse, with a screen reader and with limited vision. That is implemented, but it has not been verified in full.

Updated: 7 November 2026

Implemented

All controls are reachable with the keyboard and have a visible focus outline.
The quality slider and the background choice are linked to visible labels and explained by help texts.
Status messages about conversions and errors are announced through a live region.
Text colours meet at least the WCAG AA contrast ratio on their surfaces.
Buttons are at least 44 pixels high; there are no actions that appear only on mouse hover.
With reduced motion enabled, transitions and animations are dropped.
Hidden settings are not in the DOM and are therefore not reachable by keyboard.

Known limitations

The quality slider is a native input; its appearance differs between browsers and operating systems.
Preview images are described by their file name. The image content itself is not described automatically.
Error messages for individual files can be long; they are also available as a status message.
No review by an external body and no complete test with all assistive technologies has been carried out.

Feedback

If you notice a barrier, a short description including browser and assistive technology helps. The contact option is currently open; see the contact page.
