How to adjust the colors of 50+ images at once
Batch processing is the real time-saver. This Image Color Adjuster Pro guide shows how to handle a whole folder of images in one pass.
Doing one image at a time is fine. Doing 50 of them is a different problem entirely — and exactly where most browser tools fall apart. Image Color Adjuster Pro handles batches by design, processing them through the same in-browser pipeline as single files without re-uploading anything.

The batch workflow
- Open Image Color Adjuster Pro.
- Select all the images at once. Drag a whole folder onto the drop area, or use Ctrl/Cmd+A in the file picker.
- Set the options once — they apply to every image in the batch.
- Start the run. Image Color Adjuster Pro processes them sequentially; progress shows file-by-file completion.
- Download — usually a single ZIP with every result inside, named after the original images.
How long does a batch take?
Roughly the same time as one image, multiplied by the count. A small image processes in well under a second; 50 of them take under a minute. Larger images (video, scanned PDFs) scale linearly — budget a few seconds per file. Your CPU is the limit, not the network, because nothing is being uploaded.
Memory and browser limits
Image Color Adjuster Pro stages the work so the browser only holds a few images in memory at once, not all 50. This means you can safely batch hundreds of files on a normal laptop — the limit is your patience, not the browser's RAM.

When batching saves real time
Examples where batch processing pays off:
- Wedding photo cleanup — a thousand-image album, processed at once, downloaded as a single ZIP.
- Monthly invoice archive — every PDF for a year, compressed and stripped of metadata in one pass.
- Bulk format conversion — every HEIC photo from a trip, converted to JPG for sharing.
- Document scan run — a folder of scanner output, all run through the same cleanup, all named consistently.
Frequently asked questions
Are batches faster than processing files one at a time?
Slightly faster end-to-end because there's no re-initialisation between files. But the big win is your time, not CPU time.
What if one file in the batch fails?
Image Color Adjuster Pro skips the failed file, continues with the rest, and reports the error at the end. You can re-run just the failed one separately.
Will all files in the batch get the same settings?
Yes — that's the whole point of batching. If you need different settings per file, run them in separate batches.
Can I cancel a batch midway?
Yes — close the tab. Image Color Adjuster Pro doesn't keep anything; files already processed are saved in your downloads, unfinished ones are simply lost.
