Create a ZIP file online, free: drop the files you want to bundle, press Create ZIP, and download one archive built in your browser. One ZIP is easier to attach to an email, upload to a form that takes a single file, or hand over as a set of photos or documents. Nothing is uploaded on the way; the archive is assembled on your own device. Compression is automatic: JPG, PNG, WebP, AVIF, MP4, MP3 and existing archives are stored as they are, because compressing them again saves almost nothing, and everything else is deflated. One ZIP can hold up to 500 files or 2 GiB.
How it works
- Drop the files, or choose them. You can keep adding more, and the list shows each file’s size and the running total.
- Press Create ZIP. Each file is stored or compressed according to its type, so there are no settings to get wrong.
- Download the ZIP: archive.zip for several files, or the file’s own name with -zipped for one. The result line shows the size before and after.
Questions
- Why didn’t my ZIP get much smaller?
- Most of what people zip is already compressed. JPG and PNG photos, MP4 video, MP3 audio and existing ZIP, RAR, 7z or gzip files gain next to nothing from a second pass, so they are stored unchanged to save time. Plain text, CSV, logs, code and uncompressed formats such as BMP or WAV are where a ZIP really shrinks.
- Can I zip a folder?
- Not as a folder. Select the files inside it instead: they go into the ZIP side by side at the top level, without subfolders. Two files with the same name are both kept, as photo.jpg and photo-2.jpg, rather than one overwriting the other.
- Can I password-protect the ZIP?
- No. The ZIP is written without encryption, and there is no password option. What the page does do is build the archive on your own device, so the files are never uploaded to make it. For sensitive contents, encrypt the finished ZIP with software made for that.
- Does my file get uploaded?
- No. The models and all processing run inside your browser on your own device. You can verify this yourself: open your browser’s DevTools, watch the Network tab, and process a file: there are no uploads. After the first visit most tools also work fully offline.
- Are password-protected archives supported?
- Encrypted ZIP entries and password-protected RAR/7z archives are detected and reported honestly. A password prompt is on the roadmap, but nothing is silently skipped today.
- Why RAR and 7z but ZIP output only?
- Reading RAR and 7z uses the open libarchive project. Writing RAR is proprietary to WinRAR, and 7z output has little reason to exist here, since ZIP opens on every device without extra software.
