Format notes
- Transparency depends on browser WebP export support.

- Keep PNG for pixel-exact workflows.

Frequently asked questions
Are my images uploaded?
No. ImgShrink processes selected images in your browser and does not upload them to a server.
Do batch tools upload files or save history?
No. The queue runs locally in your browser, and ImgShrink does not create an account, database record or saved image history.
Why is an output format unavailable or different?
The browser controls image decoding and export support. Some browsers may not export AVIF or may flatten unsupported transparency.
