Bug reports, feature requests, awkward questions about privacy — all welcome.
We read everything. Please include your browser and, if you are reporting a problem with a specific archive, roughly how large it is and how it was created.
Write to usThis is a small project, so replies may take a few days. Every message is read by a human.
Useful things to include
A bug
What you did, what happened, and what you expected instead. Your browser and operating system help a lot. Please do not send us the archive itself — describe it instead.
An archive that will not open
Tell us how it was created (which tool, which platform) and roughly how big it is. Most failures come from encryption or an unusual ZIP variant, and knowing the source narrows it down quickly.
A feature request
Support for other formats such as RAR, 7z and TAR is the most requested addition and is on the roadmap. Tell us what you actually need and it helps us prioritise.
Privacy or security
If you have found a security issue, please report it privately first and give us a chance to fix it before disclosing it publicly.
