Zip Builder

The archive is assembled in the page, so the files never leave this device. Return to the picker to add more files, and use Remove to drop one. Two files with the same name get a numeric suffix rather than overwriting each other.

About this tool

Pick a handful of files and get one zip back, without installing anything. The archive is assembled in the page from the bytes already on your disk, so nothing is uploaded, and a compression level lets you trade a little time for a smaller download.

Questions

Why do two files with the same name both survive?
A zip cannot hold two entries under one name, so the second becomes name-1, then name-2 and so on. That keeps both files instead of quietly losing one.
Which compression level should I use?
The balanced level suits almost everything. Store only is quicker and is the right choice for files that are already compressed, such as a JPEG or another zip, where no level can help.
Is there a size limit?
Only what your device’s memory allows, since the archive is built in the page. A few hundred megabytes of photographs is fine on a desktop and heavy on a phone.
