Frequently Asked Questions

What compression algorithms are supported?

We support gzip, deflate, and brotli compression algorithms for text data.

Is there a file size limit?

Since tools run in your browser, the limit depends on your device memory. Most tools handle several megabytes without issues.

Can I decompress data produced by other software?

Yes. The decompression tools accept standard gzip, deflate, and brotli streams from any compliant source — command-line tools, web servers, or other libraries.

Why does the compressed output look unreadable?

Compressed data is binary, not text. Use Copy as Base64 or download it as a file — pasting raw compressed bytes into a text field will show garbled characters.
