How to generate 50 colors at once
The fast way to bulk-generate colors when you need a whole batch. Browser-based, free, no signup, runs entirely on your device.
Doing one color at a time is fine. Doing 50 of them is a different problem entirely — and exactly where most browser tools fall apart. Color Picker handles batches by design, processing them through the same in-browser pipeline as single files without re-uploading anything.

The batch workflow
- Open Color Picker.
- Select all the colors 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 color in the batch.
- Start the run. Color Picker processes them sequentially; progress shows file-by-file completion.
- Download — usually a single ZIP with every result inside, named after the original colors.
How long does a batch take?
Roughly the same time as one color, multiplied by the count. A small color processes in well under a second; 50 of them take under a minute. Larger colors (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
Color Picker stages the work so the browser only holds a few colors 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
Can I cancel a batch midway?
Yes — close the tab. Color Picker doesn't keep anything; files already processed are saved in your downloads, unfinished ones are simply lost.
Is there a maximum batch size?
Not a hard one — we've seen users process 500+ files in a single session. The practical limit is your computer's patience.
What if one file in the batch fails?
Color Picker skips the failed file, continues with the rest, and reports the error at the end. You can re-run just the failed one separately.
Does the ZIP download work on mobile?
Yes — both iOS and Android handle ZIPs from browser downloads. You can extract them with the built-in file manager.
