Compression results vary by file type
Text, source code, and uncompressed data often shrink substantially. JPEG, MP4, PDF, and other formats that are already compressed may show little improvement or can make the ZIP slightly larger.
File Compressor
Package multiple files into a single ZIP archive without uploading them. Choose an archive name and compression level, generate the ZIP locally, and review the original and compressed sizes before downloading.

Local browser processing
ZIP creation happens in your browser with no file upload. Very large inputs still depend on the memory available to the browser and device.
Frequently asked questions
Are my files uploaded?
No. The ZIP archive is created locally in your browser.
Why did a compressed file barely get smaller?
Many media and document formats already use compression, leaving little redundant data for ZIP compression to remove.
Which compression level should I choose?
Level 6 is a practical default. Lower levels are faster, while higher levels may reduce compressible files further but take longer.
