- Select the files you want to include; you can pick several at once.
- Submit the form to build the archive.
- Download the resulting ZIP file.
Why Put Files in a ZIP
- Many upload forms accept one file, so an archive lets you send a set.
- A single attachment is tidier than a dozen separate ones.
- Text-heavy files such as documents and spreadsheets often compress well.
- Grouping related files keeps them together for storage or handover.
Limits
- Between 1 and 20 files per archive.
- Requests are rate limited to ten per minute from the same address.
- Files are stored in the archive by name only, without their original folder structure.
Files That Will Be Skipped
For safety, executable and script files are not added to the archive. That covers extensions such as .php, .exe, .sh, .bat, .cmd, .com, .msi, .ps1, .vbs, .jar and .cgi, along with the numbered PHP variants.
These files are skipped silently rather than causing an error, so if you select only excluded files the archive may come back empty. If something is missing from your download, this filter is the likely reason.
Other Limitations
- There is no password protection or encryption option.
- The compression level is not adjustable.
- Because only file names are stored, two files with the same name will collide and one will be lost.
- Already-compressed files such as JPG, MP4 or MP3 will barely shrink, since their data is compressed already.
Privacy and Processing
The archive is built on our server, so your files are uploaded. They are used only to create the ZIP, the download is removed after it is sent, and temporary files are cleared automatically.
ZIP Compressor FAQ
How many files can I add?
Between 1 and 20 files per archive. Requests are limited to ten per minute from the same address.
Why is a file missing from my archive?
Executable and script files are excluded for safety, covering extensions such as .php, .exe, .sh, .bat, .cmd, .com, .msi, .ps1, .vbs, .jar and .cgi. They are skipped silently, so if you selected only excluded files the archive may come back empty.
Can I password-protect the ZIP?
No. There is no encryption or password option on this page. If you need a protected archive, use desktop archiving software.
Why did my images barely compress?
Formats such as JPG, MP4 and MP3 are already compressed internally, so there is little redundancy left for ZIP to remove. Text-based files like documents and spreadsheets compress much better.
Is the folder structure preserved?
No. Files are stored by name only, without their original folders. This also means two files with the same name will collide and one will be lost.
Are my files uploaded?
Yes. The archive is built on our server, so your files are uploaded. They are used only to create the ZIP, the download is removed after it is sent, and temporary files are cleared automatically.
