FAQ
Common questions about GZIP compression.
What is GZIP compression?
GZIP compresses a single data stream losslessly, producing a .gz file that any standard tool can decompress.
Can I compress multiple files?
GZIP covers one stream at a time. For several files, bundle them into a TAR first, then compress the TAR.
Is the output compatible?
Yes. The output is a standard .gz file readable by gzip, browsers and most web servers.
Is compression lossy?
No. GZIP is fully lossless — decompressing restores the original bytes exactly.
Are there size limits?
No artificial limits, subject to your browser memory.
Is my file uploaded?
No. Compression happens entirely in your browser.
