How many images can I resize at once?

As many as your device's memory allows — there's no server-imposed limit, and results download together as a ZIP.

Is the Batch Image Resizer free to use?

Yes. Batch Image Resizer is completely free with no sign-up, no watermarks and no usage limits.

Are my files uploaded to a server?

No. Batch Image Resizer runs entirely in your browser — your files and data never leave your device.

Does it work on mobile and offline?

Yes. It works in any modern browser on desktop or mobile, and the toolkit is a PWA that keeps working offline after your first visit.
