About merge.zip
A small utility with a simple promise.
Build useful archives without handing your files to somebody else’s server.
Local from start to finish
File reading, archive browsing, and ZIP creation happen inside your browser. Your source files are not uploaded to merge.zip.
Made for merging
Add loose files or open one or more ZIP archives, choose the entries you want, resolve duplicate names, and save one clean output.
Speed without tricks
Existing ZIP entries keep their compressed data whenever possible. That avoids the expensive decompress-and-recompress cycle used by many browser tools.
Honest boundaries
Archive browsing currently supports standard ZIP files. ZIP64 and password-protected archives are identified clearly instead of failing silently.
