How to resize or compress many images at once and download one ZIP
4 minutes, updated 2026-11-09
Product listings, a photo album for a website, scanned pages for an application: the job is the same for every file, so it should be done once for all of them. Every tool on this site takes as many files as you drop and returns them together.
Decide the rule first
| Goal | Tool | Setting |
|---|---|---|
| Every image the same width | Resize | Pixels, width only, Fit inside |
| Every image exactly the same shape | Resize | Width and height, Crop to fill |
| Every file under a size limit | Fit to a KB size | The limit, Auto format |
| Smaller files, same pixels | Compress | Quality 80, Auto (keep format) |
| Every image in one format | Convert | The target format |
Run it
- Set the options before dropping files; changing them later reruns the whole batch.
- Select all the files in the file picker, or drag the folder's contents onto the page.
- Watch the list: each row shows the original and the result side by side, and the total saving appears at the end.
- Open 'Compare' on a few rows to check quality, especially the most detailed photos.
- Download all as one ZIP, or files one by one.
Names and originals
Results are renamed with what changed, such as photo-1200x800.jpg or photo-min.jpg, so they never overwrite the originals when you unzip them into the same folder. Keep the originals: a resized or compressed copy cannot be turned back into the full-quality file.
How many at once
There is no limit on count or size from this site, because the work happens on your device. A laptop handles hundreds of phone photos in a few minutes; a phone does best with batches of twenty to fifty. Files are processed one after another so the page stays responsive, and anything not yet started can be removed from the list.
