Will conversion lose anything?

File contents and folder structure are preserved exactly. Format-specific metadata (e.g. Unix permissions on TAR) is best-effort because not every format records the same fields.

Can I convert encrypted archives?

Not directly. Decrypt first with Unlock ZIP, then convert the plaintext result. We never re-encrypt automatically because that requires asking for a new password.

Why does the new file change size?

Different formats use different compression algorithms. 7z (LZMA2) usually beats ZIP (DEFLATE) on text and source code. TAR alone is uncompressed and will be larger.

How big can the source archive be?

Limited only by your browser’s available memory. Multi-gigabyte conversions work on a desktop with enough RAM but can stall on mobile.
