Join split files
Got a stack of .part1, .part2, .003 files? Drop them all here and get the original file back, byte for byte.
Parts are combined locally on your device — nothing is uploaded.
How to rejoin split files
- Add all the parts. Select them together — order doesn't matter, they're sorted by number automatically.
- Check the list. The tool flags missing part numbers so you don't build a corrupt file.
- Join & download. The original file is reassembled and downloads instantly.
Frequently asked questions
Which naming schemes are recognized?
Anything ending in a number: video.mp4.part1, backup.zip.001, file.7z.002… Parts are sorted naturally (1, 2, … 10) rather than alphabetically, so nothing ends up out of order.
What if I'm missing a part?
The tool warns you when numbering has a gap. Every part is required — a file joined with one missing will be corrupt.
Are my parts uploaded?
No — joining happens entirely in your browser, and the rebuilt file is saved straight to your device.
