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