Keep original format or convert everything to JPEG, PNG, or WebP. Quality slider controls compression level.

📦

Download ZIP

All processed images are bundled into a single ZIP file for instant download. Nothing uploaded to any server.

Batch image resizer FAQ

Are my images uploaded to a server?

No. Every image is processed entirely inside your browser using the Canvas API. Your files never leave your device and the tool works offline after the page has loaded.

Does "fit inside" preserve aspect ratio?

Yes. Fit inside scales the image down so that neither width nor height exceeds the values you set, while keeping the original aspect ratio. Images smaller than the target are not upscaled.

What is the maximum file size per image?

There is no enforced limit. Very large images (over 20 MP) may be slow to process in the browser due to Canvas memory limits, but there is no server-side restriction.

Can I process animated GIFs?

The tool processes only the first frame of animated GIFs. For full animated GIF editing use the Video to GIF tool.
