Bulk Image Resizer

You can add up to 50 images in one batch on desktop, or 20 images on smaller devices. If you try to add more, the extra files are skipped so the current batch stays within the limit.

The batch uploader accepts JPG, PNG, GIF, WEBP, and AVIF files, as long as they stay within the normal file size limit for this tool.

Yes. The batch page is built around one shared setup, so your chosen size, percentage, file size target, and export format apply across the whole batch.

The missing side is calculated automatically for each image, so every file keeps its own original shape while still following the single dimension you entered.

Yes, but only when the export format is PNG. In other formats, the tool uses a color fill because those formats do not keep transparency the same way.

No. That control only works with JPG and WebP output, so it is disabled when PNG is selected as the export format.

No. The batch workflow runs in your browser, so your files stay on your device while the page prepares previews, processing, and downloads.

The batch moves to a separate download workspace where each image finishes one by one. You can preview individual results, download them separately, or save the whole batch as one ZIP.

Yes. You can resize and download images for free, with no signup required. Processing happens locally in your browser, so there are no usage caps or hidden fees.

No. All resizing and compression run in your browser. Files never leave your device and are not stored on our servers, keeping your images private.
