What This Tool Does
ZIP compression: Combines multiple files into one ZIP for sharing, backup, or email. Up to 20 files per archive, each up to 50MB. Output is a standard .zip any device can open.
File limits: Maximum 20 files per archive; each file must be 50MB or smaller.
Security: Certain types (e.g. .exe, .php, .sh, .bat) are excluded to reduce risk from executables or scripts.
Use cases: Bundling documents and images, small backups, or attachments for email and cloud upload.
Select 1–20 files (50 MB each per the picker). The server builds a flat-name ZIP—no folders—and skips executable/script extensions silently. Upload required; ten archives per minute.
Build the archive
- 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
- 1–20 files; 50 MB per file (UI copy matches validation).
- Ten requests per minute.
- Names only—duplicate filenames collide; no directory tree.
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.
Upload
Files are sent to our server for zipping, then discarded from a personal library. See the Privacy Policy.
ZIP creation questions
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 and are not kept as part of a permanent user file library. See our Privacy Policy for details.
