Frequently asked questions
- Is my text uploaded to a server?
- No. Compression and decompression happen entirely in your browser using the native CompressionStream API. Your data never leaves your device.
- What compression algorithm is used?
- Gzip, a widely supported lossless compression format. The output is the raw gzip bytes encoded as base64 text for easy copying and sharing.
- Can I decompress data compressed by other tools?
- Yes, as long as the data is gzip-compressed and then base64-encoded. Paste the base64 string and click Decompress to recover the original text.
