About ZIP File Creator
Compresses data using the PKZIP algorithm with the given filename. No support for multiple files at this time.
Input: binary bytes (text input uses UTF-8; a file retains its original bytes). Output: a file.
Format reference: Zip background and specification
Example
Use “Try example” to load this public sample and its settings, then run it.

Before interpreting the result
Select the actual container or compression format: gzip, zlib and raw DEFLATE are different. Decompression can expand small inputs substantially. The runner limits output and execution time.
How to use this page
- Paste your input or open a local file.
- Adjust tool options if needed, then choose Run tool.
- Copy the result or download the original output bytes.
Inputs and results are not added to the public catalogue or saved in the URL. Processing happens in your browser; HTTP Request and DNS over HTTPS send the requests you explicitly run. Files up to 128 MiB can be opened; decompression and image tools may have smaller processing limits. Large results have a shortened preview. Text and HTML downloads use UTF-8; binary downloads preserve output bytes. Pasted text follows browser newline handling; open a file when exact input bytes matter.
