Zip Files
Combine multiple files into a single downloadable .zip archive. Runs entirely in your browser — files are never uploaded to a server.
Click to upload or drag and drop
Select one or more files to zip
How it works
Add one or more files — you can keep dropping more in and remove any you don't want — then press Create Zip. The archive is built in your browser with the JSZip library and offered on a download page as firstfile-archive.zip, named after the first file in the list.
The zip is not compressed
Files are stored in the archive without compression, so the .zip comes out about the same size as the originals: it bundles files but won't shrink them. To make a large file smaller, compress it first, for example with Compress PDF or Image Compressor.
Limits
Each file can be up to 100 MB. The archive is flat, so select the files themselves rather than folders — folder structure is not kept. If two files share a name, only the last one added ends up in the zip. The archive isn't password-protected.
A worked example
Add report.pdf, photo.jpg and notes.txt. They appear in the list in the order added, and pressing Create Zip builds report-archive.zip, named after the first file. It holds three entries at the top level with their exact original names. If the files are 2 MB, 5 MB and 1 MB, the archive is about 8 MB plus a little for the archive's own headers, since nothing is compressed.
How the list behaves
Each drop appends to the list and Remove takes out one entry. Adding or removing a file clears any download you already made, so create the zip again afterwards. The archive's name follows whichever file is first at that moment, so removing the first file renames the result. Two files with the same name appear twice in the list, but the zip keeps only the last one, so rename one beforehand.
What is not included
There are no compression settings, no password and no folders: the archive is flat. Each file can be up to 100 MB, and everything is read into memory when you press Create Zip, so several files near that size can slow the browser.
Frequently asked questions
Is there a limit to how many files I can zip?
No hard-coded limit, but zipping many large files uses more of your browser's memory since everything happens locally rather than on a server.
Why is my zip file not smaller than the originals?
The files are stored in the archive without compression, so it bundles them but does not shrink them. Compress large PDFs or images first if size matters.
What is the zip file called?
It is named after the first file in your list, with -archive added, for example report.pdf gives report-archive.zip.
What happens if two files have the same name?
Only the last one added ends up in the archive, because a zip entry is identified by its name. Rename one of the files before adding it.
