Run Collage Maker on a whole folder of files

Drop a folder, get a folder back. The bulk workflow with Collage Maker when you have dozens of files to process the same way.

Tool:Collage Maker

Doing one file at a time is fine. Doing 50 of them is a different problem entirely — and exactly where most browser tools fall apart. Collage Maker handles batches by design, processing them through the same in-browser pipeline as single files without re-uploading anything.

Launch the tool: Collage Maker — No upload, no signup, no daily limit.

The batch workflow

  1. Open Collage Maker.
  2. Select all the files at once. Drag a whole folder onto the drop area, or use Ctrl/Cmd+A in the file picker.
  3. Set the options once — they apply to every file in the batch.
  4. Start the run. Collage Maker processes them sequentially; progress shows file-by-file completion.
  5. Download — usually a single ZIP with every result inside, named after the original files.

How long does a batch take?

Roughly the same time as one file, multiplied by the count. A small file processes in well under a second; 50 of them take under a minute. Larger files (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

Collage Maker stages the work so the browser only holds a few files 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

What if one file in the batch fails?

Collage Maker skips the failed file, continues with the rest, and reports the error at the end. You can re-run just the failed one separately.

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.

Can I cancel a batch midway?

Yes — close the tab. Collage Maker 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.
