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.

How to use this tool

Open the Convert Archive tool
Visit makemyzip.com/convert-archive. The source format is detected automatically from the file you drop.
Drop the source archive
Drag a ZIP, 7z, TAR, or GZ file onto the dropzone. Nothing uploads — both extraction and re-packing happen locally.

Choose ZIP, 7z, TAR, or TAR.GZ as the destination. The original archive is left untouched.
Convert and download
The tool extracts the source in memory and re-packs into the new format. Folder structure is preserved.
