Batch Image Converter is a free online tool that resize, compress and convert dozens of images at once, then download them as a ZIP. It runs entirely in your web browser using plain JavaScript, so files are processed on your own device and never uploaded to a server. There is no sign-up, no file size limit imposed by the site, no watermark and no paid tier.

About Batch Image Converter
Doing one image at a time is fine until you have forty product photos to prepare. This runs the whole set through the same pipeline and hands you a single ZIP — built in your browser, so a folder of client photos never touches anyone else's server.
How to use it
- Everything batch image converter needs is on this page.

Questions
Which browsers does this work in?
It relies on plain JavaScript, supported in current versions of Chrome, Edge, Firefox and Safari. Features needing camera, microphone or screen access will ask permission first, and that prompt comes from your browser rather than from this page.
