Drag and drop works here too.1–500 files, 100 MB each and 500 MB combined. Any file type packs; nothing runs.
Names are sanitized and checked before anything packs: absolute paths, traversal segments, and duplicate names refuse the batch with the reason named. Level 0 stores bytes unchanged; levels 1–9 deflate deterministically. Packed files are never executed or opened — bytes in, archive out. Everything runs in this tab.
Result
No archive yet.
Add files, arrange them, then create the archive.
ZIP Creator bundles up to 500 files into a single archive without uploading anything: pick a compression level, keep folder structure or add a prefix, and download one ZIP. Every name is sanitized before packing, so absolute paths, escapes, and collisions fail loudly instead of shipping. Archive paths are sanitised before packing: an absolute path, a traversal segment or a duplicate name refuses the batch with a reason rather than writing a surprising archive. The archive is written in the browser, and the page reports the final size before you download it.

Frequently asked questions about ZIP Creator
Does ZIP Creator upload my files?
No. Reading, compressing, and assembly run in your browser — in a background worker when one is available — and the archive only ever becomes a download.
What compression level should I pick?
Level 0 stores bytes unchanged and is fastest. Levels 1–9 deflate; 6 balances size and speed, 9 squeezes hardest and takes longest.
Why was my batch refused?
Unsafe names, duplicates after sanitizing, and size ceilings all refuse with the reason named. Fix the listed files and pack again.
Are packed files executed?
Never. Files are read as bytes and written into the archive untouched; nothing runs, opens, or previews them.
