Create ZIP archives from any files with adjustable compression
Built & maintained by Pappu Venkata Subbi Reddy, founder of Clacify
Clacify's ZIP Creator lets you bundle any collection of files into a ZIP archive directly in your browser. Drag and drop files from your computer, give the archive a name, choose a compression level (Store for already-compressed files like JPG/MP4, Best for text documents and code), and click Create. The ZIP is built entirely in your browser using the fflate library — one of the fastest JavaScript ZIP engines — and downloads instantly. Nothing is uploaded to any server.
Open Clacify's ZIP Creator in any browser, drag and drop the files you want to archive, enter a name for the ZIP, choose compression level, and click 'Create & Download ZIP'. The ZIP file downloads to your device in seconds — no WinZip, 7-Zip, or macOS Archive Utility needed.
For photos (JPG, HEIC), videos (MP4, MOV), and audio (MP3, AAC) — use Store (level 0) since these are already compressed; further compression adds time without reducing size. For documents (DOCX, XLSX), code, text files, and CSV — use Best (level 9) for the smallest possible ZIP. For a mix of files, Default (level 6) is the best balance.
