Resize a folder of images in one pass

The job

Resizing one image is easy; resizing twenty by hand is where people give up and upload them anyway. The batch resizer applies the same rule to a whole selection — fit inside a box, scale by percent, or set the long side — and hands back a single ZIP.

Batching a set

Choose up to 20 images (10 MiB each). Pick a mode, the target size, and the output format, then download the ZIP.

• Fit inside a box: longest side shrinks to fit — good for galleries.
• Long side: a single max dimension — the common 'max width' case.
• Percent: scale everything the same amount — the only mode that also enlarges.
• Keep format or convert: output can be PNG, JPG, or WebP for all files.

Worked example

20 product photos, mixed 3000–5000 px, needed at max 1200 px wide for a shop page: choose 'long side' = 1200, format WebP, download — one ZIP of consistent product images, often 90% smaller on disk.

Where it stops

Fit and long-side modes shrink only — they won't blow up a 200 px thumbnail to 1200 px. Combined ZIP output is capped at 96 MiB; very large sets may need two runs. Animated images become stills. For different crops per image, use the single image resizer.
