Email said 25 MB. The file is 80. SplitShift cuts a file into parts in the browser and joins those parts back, without an upload. It is a byte slicer, not a ZIP, not a video splitter, not a PDF page splitter. Use it when a transport cap is the only problem and the recipient can run the join. Do not use it as a backup strategy, a way to hide a file, or a substitute for actually compressing a 4K video. If the recipient cannot join, you have created a puzzle, not a delivery.
Split: pick a size (10 MB, 25 MB, custom), download part files with numeric suffixes. Join: drop every part, in order, download the original bytes. Missing a part means a truncated file that may look 'almost' and then fail to open. Check hashes with HashShift after join if the file matters. The tool does not add a fancy container with parity. It is honest concatenation.
When not to use it: the real issue was a video that should have been transcoded (VidCompressShift), a PDF that should have been compressed, or a set of files that should have been a ZIP. Also skip it if the other person is on a phone mail app that cannot download seven parts and join them. Split is a last-century email move that still works for two engineers.
Privacy is local. Parts of an ID scan still sit on your disk. Naming parts 'invoice.part1' in a shared folder is your disclosure. The browser never needed the bytes on a server. Join the parts, hash, delete the parts if you do not want seven copies of a secret. Phone mail apps that cannot download seven parts are a reason to compress or use a real drive instead.
A 72 MB WAV the label wants, email cap 25 MB. SplitShift makes three ~24 MB parts. You send three mails. They join in the tab, HashShift SHA-256 matches the value you put in the first mail. A fourth part never existed; if one mail had bounced, the WAV would have been garbage. You also keep a FLAC in cloud storage as the adult delivery. Parts never uploaded to a splitter site.
Split and join run in the browser. The file never uploads. Parts on disk are still copies of the secret. Hash after join, then delete parts you do not need. Close the tab when finished. Parts on disk are still copies of the secret even though the browser never uploaded the bytes.

No. A split ZIP is a format some archivers speak. SplitShift is raw chunks you must join with the same tool (or cat). Do not tell WinRAR to open part2 as a RAR.
Use PDFShift for pages. SplitShift will cut in the middle of a stream and produce a corrupt PDF. PDFShift splits pages; this booth will cut in the middle of a stream and give you a corrupt PDF.
Numeric order of the parts, all of them. If the UI lists them, check the list before you confirm. One missing 10 MB chunk is a silent truncation. Numeric order, all parts, check the list before confirm; one missing chunk is a truncated original.
If compression actually shrinks (video, PDF scans), do that first so there are fewer parts. If the file is already a ZIP of JPEGs, just split. Compress first when compression actually shrinks, so you mail fewer parts to the person joining.
