Compress Gzip Base64
GZIP-compress any text or JSON and encode the result as Base64 — instantly in your browser. Choose compression level and output format.
The Compress Gzip Base64 tool takes any text or JSON payload, compresses it with the GZIP algorithm, and encodes the binary result as a Base64 string — ready to drop into an API request, HTTP header, or IoT platform attribute.
You can choose a compression level from 1 (fastest) to 9 (best), and toggle URL-safe output for use in query strings or JWT-style tokens that cannot contain +, /, or =.
All processing happens entirely in your browser using the pako library — nothing is ever sent to a server.
