Use a positive whole number. A part contains at least one byte, except for an empty original.
Drag the handle, use arrow buttons, or press arrow keys on the handle to change order. Merging checks the displayed order against the checklist.
Split a file into smaller byte fragments for storage or transfer, then restore the original from those parts. Choose a number of parts or a byte size, and download a checklist that records filenames, order, lengths, and checksums.
Keep every part and the checklist together. Merging checks the selected order and each part before making the restored file available.
Yes. Splitting preserves the original bytes and works independently of file format. The parts are fragments, so a video, audio, archive, or document part may not open independently. Merge the complete set to restore the original.
Keep every unchanged part and the generated JSON checklist. The checklist records the original name and byte length, the part order and lengths, and MD5 checksums for accidental corruption checks. It is not a digital signature.
Merging stops when filenames, counts, lengths, or order do not match the checklist. Use checklist order to fix the order, remove repeated files, or select missing parts. Damaged content fails checksum verification.
There is no fixed source size or part count limit. Counts and sizes must be positive safe whole numbers, and nonempty parts contain at least one byte. Browser storage and memory can still limit a task; retain the original and retry if needed.
Reading stops and completed parts stay available. Retry with the same input to create a complete set and checklist. Changing input, mode, or split settings clears previous results.
