Batch Image Compressor

Batch Image Compressor: Compress Many Photos to One Target Size

Compressing photos one at a time is slow when a form, a listing, or a website needs twenty of them under the same limit. Upload the whole set, enter a single target size in KB, and ConvertBrio compresses every image to fit.

Each file is handled on its own, so one problem file never blocks the rest. You get a per-file report, individual downloads for every image, and a ZIP of the whole batch.

How to use this tool

1. 1

   Select your images

   Drop up to 50 images at once, up to 100 MB in total.

2. 2

   Enter the target size

   One limit in KB applies to every image.

3. 3

   Compress

   Each image is processed independently: quality is lowered first, and dimensions shrink only if needed.

4. 4

   Download

   Save individual files from the list, or download everything as a ZIP.

Per-file results, not all-or-nothing

The results list shows each file, the size it reached, and whether it stayed within the target. If an image can't get under the limit without extreme quality loss, it's flagged as above target instead of silently passing. A file that can't be read at all is reported as failed, while the others complete normally.

How each image is compressed

For every image, the tool searches for the highest quality that fits your target in the same format (JPG stays JPG, WEBP stays WEBP). If even the lowest quality is too large, it reduces the dimensions in small steps. HEIC photos from iPhones are converted to JPG because HEIC isn't a supported output format. Animated GIFs keep only their first frame.

When to use batch vs. single

Use the single Compress Image tool for one file. Use batch when many images share the same limit, for example uploading a product set, a set of documents to a portal, or photos for an email.
