ZIP Creator — Make a ZIP Archive Online

Five attachments where one would do, a folder of logs to send to support, a project to hand over — packing files into a single ZIP archive is still the everyday way to move a bundle of files as one. This ZIP creator does it without an archiver app and without uploading anything: add files, choose a compression level and download the finished .zip.

The file list is fully editable before you commit: add files in several rounds, remove ones you picked by mistake, and keep relative folder names when you select a whole directory. Two files with the same name are automatically renamed with a numbered suffix so nothing silently overwrites anything at extraction time.

The compression level select is real, not decorative. Level 0 stores files without compression — instant, useful for bundling already-compressed media. Level 6 is the balanced default, and level 9 squeezes hardest at the cost of speed. After creation the tool reports the actual size change, and it is honest about the physics: jpg, mp4 and other already-compressed formats will not get meaningfully smaller no matter the level.

Compression runs on your device via the fflate engine, so the tool is safe for confidential files and works offline once the page is loaded. When you need the reverse — seeing what is inside an archive — our ZIP Extractor opens any .zip in the browser the same private way.
