When a ZIP makes sense
Bundling files for email or sharing
Bundling files to send via email or a sharing link is the classic use. Email attachments and file services work with individual files — if you need to send a folder of assets, a set of photos, or a collection of documents together, zipping them first keeps everything in one organized package with a single download for the recipient.
Archiving a finished project
Archiving a finished project is another practical reason. When work wraps up, the files do not need to stay in active storage. Zipping the folder and keeping the archive saves space and keeps everything together for future reference without cluttering your working directory.
Handing off design files or source code
Handing off design files or source code to a client or collaborator. A ZIP of design assets, font files, or a codebase is the standard way to share work outside of version control. Max compression works well for code and documents; for already-compressed files like photos or videos, Default or None is faster with similar results.
Frequently asked questions
Are my files uploaded to a server?
No. Everything runs entirely in your browser using JavaScript. Your files never leave your device.
What compression levels are available?
None (store only — fastest, no size reduction), Fast (level 1 — quick with light compression), Default (level 6 — best balance of speed and size), and Max (level 9 — smallest output, takes longer for large files).
Is there a file size limit?
There is no hard limit — processing happens in your browser, so the practical limit depends on your device's available memory. Files up to several hundred MB work fine on modern devices.
What file types can I zip?
Any file type. Images, documents, code, videos, audio — you can add any combination of files to the ZIP.
Can I extract password-protected ZIPs?
No. Password-protected (encrypted) ZIP files cannot be extracted by this tool. You will need to remove the password first.
Does the ZIP preserve folder structure?
Files added individually are placed in the root of the ZIP. The browser's file picker works with individual files only, not folders. To preserve a folder structure, zip the folder first using your operating system's built-in tool, then share that archive.
Can I extract formats other than ZIP?
This tool supports ZIP files only. RAR, 7-Zip, tar.gz, and other archive formats are not supported. For those formats you will need a desktop application such as 7-Zip on Windows or The Unarchiver on Mac.
Which compression level should I choose?
Default (level 6) is the right choice for most files — it gives a good balance of speed and size reduction. Max compression works well for text-heavy files like code or documents. For already-compressed formats like JPEG images or MP4 videos, choose None — they will not compress further and the extra processing time is wasted.
