About FastMinify

Browser-based developer tools platform

FastMinify gives developers fast, private formatting and conversion utilities: no toolchain to install, no code sent to a server. Minification is where it started. The platform now covers minify, convert, encode, JSON, SVG, DevOps and more.

Version 1.10.10

Why FastMinify

Privacy-local processing

Tool input stays in your browser and nothing is uploaded for processing. You can check it yourself on the local processing page.

Verify local processing

One platform, many clusters

Minify, convert, encode, JSON, SVG, DevOps, API utilities and more, grouped into focused hubs instead of scattered one-off sites.
