File Joiner

Combine split file chunks back into the original complete file

Free to use, no watermarks, runs in your browser—nothing uploads to our servers

Select File Chunks (in order)

Upload chunks in the correct order (Part 1, Part 2, etc.)

Order matters: Upload chunks in the exact sequence they were split (Part 1, 2, 3, etc.)
Use reorder buttons: If chunks are out of order, use the ↑↓ buttons to rearrange them
Check total size: The total size should match the original file before splitting
Verify the result: After joining, verify the file opens and works correctly
