How to generate 50 identifiers at once
The fast way to bulk-generate identifiers when you need a whole batch. Browser-based, free, no signup, runs entirely on your device.
Doing one identifier at a time is fine. Doing 50 of them is a different problem entirely — and exactly where most browser tools fall apart. Hash Generator handles batches by design, processing them through the same in-browser pipeline as single files without re-uploading anything.
Run it in your browser: Hash Generator — No upload, no signup, no daily limit.
The batch workflow
- Open Hash Generator.
- Select all the identifiers 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 identifier in the batch.
- Start the run. Hash Generator processes them sequentially; progress shows file-by-file completion.
- Download — usually a single ZIP with every result inside, named after the original identifiers.
How long does a batch take?
Roughly the same time as one identifier, multiplied by the count. A small identifier processes in well under a second; 50 of them take under a minute. Larger identifiers (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
Hash Generator stages the work so the browser only holds a few identifiers 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.
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.
Can I cancel a batch midway?
Yes — close the tab. Hash Generator doesn't keep anything; files already processed are saved in your downloads, unfinished ones are simply lost.
What if one file in the batch fails?
Hash Generator skips the failed file, continues with the rest, and reports the error at the end. You can re-run just the failed one separately.
