Package files into an archive
Drop one or more files and package them into ZIP, 7Z, TAR.GZ, or another archive format. This tool is useful for bundling files together, not for reducing PDF or image size.
Or paste a link to a file
Drop multiple images to combine them into one PDF, Word document, or PowerPoint presentation — or convert each image separately.
Available archive targets
Package files into ZIP, 7Z, or TAR.GZ
An image, a PDF, a video, a 3D model — anything can go into the archive of your choice as a single entry.
Bundle many files at once
Drop multiple files of any kind and we'll bundle them into one archive in your chosen format.
Bundling and compressing are two different jobs
People use "compress" for both, which is why this page needs to be clear about which one it does. Bundling puts many files into one. Compressing makes data smaller. Some formats do both, some do only one, and confusing them is why a folder of photos zipped up comes out almost exactly the same size.
This tool bundles. It packages whatever you drop into a ZIP, 7Z, TAR.GZ or similar archive, applying that format's compression along the way. If the files inside are already compressed, the archive will be close to the sum of its parts, and that is the format working correctly rather than failing.
| Format | Behaviour |
|---|---|
| ZIP | Bundles and compresses. Opens on every operating system with no extra software. |
| 7Z | Bundles and compresses harder, but the recipient needs software that reads it. |
| TAR | Bundles only, no compression. Preserves Unix permissions and symlinks. |
| GZ, XZ, ZST | Compress a single stream. They have no concept of multiple files or folders. |
| TAR.GZ | TAR bundles the files, then GZIP compresses the result — hence the two extensions. |
When repacking actually saves space
Compression works by finding redundancy. If the data has already had its redundancy removed, there is nothing left to find — so an archive full of JPEGs, MP4s, MP3s or PDFs barely shrinks no matter which format you choose. That is not a fault; those files were compressed when they were created.
The real gains are on uncompressed or repetitive data: text files, logs, CSV exports, source code, database dumps, BMP and WAV files, and folders of near-identical documents. On a large log archive the difference between ZIP and 7Z or XZ can be substantial.
If you want a smaller file, not a bundle
Making one file smaller is a different operation, and the site has dedicated tools for it. Those re-encode the content itself rather than wrapping it, which is what actually reduces size.
- A large PDF is usually large because of embedded images — use the PDF compressor, which re-encodes them.
- A photograph or screenshot — use the image compressor, or convert it to WebP, which is typically smaller than both JPG and PNG.
- A video — converting it re-encodes the footage, which is where the size actually comes down.
- Many separate files you simply need to send as one — that is this tool.
Choosing what to send someone
ZIP, in almost every case. It opens on Windows, macOS, Linux, Android and iOS with nothing installed and no instructions attached, and that reliability is worth more than the extra few percent a stronger format would save.
Reach for 7Z or TAR.XZ when you are archiving compressible data for yourself and you control both ends. Use TAR or TAR.GZ when you are sending to a Linux server or a build pipeline, since TAR preserves file permissions and symbolic links that ZIP handles poorly.
