Frequently asked questions
Which files get much smaller?
Text, CSV, JSON, code, Word and Excel documents, and uncompressed images such as BMP compress well, often by 50 to 90 percent. JPG, PNG, MP3, MP4 and existing ZIP files are already compressed and barely shrink.
Why did my ZIP come out the same size?
The files were already compressed. The tool says so in the status line. Zipping them still bundles many files into one download, which is useful for email or uploads.
Are my files uploaded to compress them?
No. The ZIP is built in your browser with JSZip and saved straight to your downloads folder.
What does Store only do?
It packs files into a ZIP without compressing them, which is fastest and useful when you only need one file to send.
Can I extract ZIP files here?
This tool creates ZIP files. Windows, macOS and phones can open ZIP files without extra software.
