Privacy without exaggerated claims
Archiwum has no file upload endpoint. ZIP is handled by a lightweight module, while RAR, 7Z and TAR use WebAssembly loaded only when needed. Ads may operate according to consent settings, but they do not receive your file contents.
Archive security
Every path is normalized. Entries attempting to escape the virtual root are skipped, links are not materialized and limits stop suspiciously large decompression results.
