How to archive splitter vs shell loops over many archives
- Step 1Compare on speed — For files under 100 MB the browser tool processes in seconds — fflate is highly optimised. CLI tools win on files over 1 GB where Node.js/V8 memory becomes the bottleneck.
- Step 2Compare on privacy — JAD's Archive Splitter runs entirely in your browser tab; the CLI runs locally too. Both are private, but the browser path also requires no install or sudo, useful on locked-down machines.
- Step 3Compare on output — Both produce standard archives readable by every consumer. The browser output sets timestamps to upload time by default — use Timestamp Normaliser if you need reproducible builds.
Frequently asked questions
When should I prefer the browser tool?+
One-off jobs, untrusted input you don't want on disk, machines where you can't install software, or quick demos where setup time matters more than throughput.
When should I prefer CLI?+
Files >2 GB, scripted pipelines, CI/CD jobs, batch processing of thousands of archives, and any workflow where the archive lives on a server you already control.
Are the outputs interchangeable?+
Yes. JAD's Archive Splitter produces standard archives — open them with unzip, 7z, tar, or any consumer that handles the format. There's no JAD-specific wrapper or metadata.
Does the browser tool handle large archives?+
Up to 2 GB on paid tiers. Beyond that, browser memory becomes the constraint. The Streaming ZIP Builder handles multi-GB outputs without RAM spikes for one specific case (creating large ZIPs from local files).
Privacy first
Every JAD Archive tool runs entirely in your browser using fflate, @zip.js/zip.js, and the libarchive WASM bridge. Your archives never leave your device — verified by zero outbound network requests during processing.
