Frequently asked questions

Is this image resizer really free?

Yes — completely free, with no signup, no email wall, and no usage limits. The tool is funded by users who upgrade to IllumeAI for AI-generated product photos.

Are my images uploaded anywhere?

No. The resizer runs entirely in your browser using the HTML5 Canvas API. Your files never leave your device.

What's the maximum file size?

There's no enforced limit. Performance depends on your device — most modern phones and laptops handle batches of 50+ images comfortably.

Can I resize multiple images at once?

Yes. Drop a batch, pick your size, and download everything as a single ZIP file.

Does it keep the aspect ratio?

By default yes — you can disable the lock to stretch the image or pick a fit mode (contain, cover, stretch) when forcing exact dimensions.

What formats are supported?

JPG, PNG, WebP and AVIF inputs. Output format follows the input unless you also use our free converter.
