Batch-converting PNG to JPG (50+ files at once)
How to convert a whole folder with PNG to JPG without uploading anything. Browser-based, free, no signup, runs entirely on your device.
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. PNG to JPG handles batches by design, processing them through the same in-browser pipeline as single files without re-uploading anything.

The batch workflow
- Open PNG to JPG.
- 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. PNG to JPG 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
PNG to JPG 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
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.
Can I cancel a batch midway?
Yes — close the tab. PNG to JPG doesn't keep anything; files already processed are saved in your downloads, unfinished ones are simply lost.
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.
