How to use
- Split: choose a file, set the part size (for example 25 MB) or the number of parts, and press Split file. Download the parts and the manifest.
- Join: drop all parts (and the manifest if you have it). Parts are ordered by number; with the manifest every part and the result are checked against SHA-256.
Worked example
A 104 MB video split at 25 MB produces five parts: four of 25 MB and one of 4 MB, plus a manifest with the original SHA-256.
Supported formats and limits
| Input | Any file (split), Parts named *.001, *.002… (or *.part001) plus the optional manifest (join) |
|---|---|
| Output | Numbered parts + manifest.json with SHA-256 per part, Rejoined original file |
| Limits | Files up to 4 GB; parts from 1 KB, up to 9,999 parts. "Download all (ZIP)" is offered up to 512 MB in total. |
| Engine | Blob slicing with streaming SHA-256 (hash-wasm) |
Limitations
- Parts are plain byte ranges; they are not individually playable or readable.
- Without the manifest the joined file cannot be verified against the original; its SHA-256 is shown instead.
Questions
Can I open one part on its own?
No. Parts are plain byte ranges, so a part of a video or archive is not playable or readable by itself. Join all parts first.
How do I know the joined file is correct?
Add the manifest with the parts. It holds the original SHA-256, and the joined file is checked against it. Without the manifest, the joined file's SHA-256 is shown so you can compare it yourself.
