Less code, fewer requests
Fast Velocity Minify processes HTML, CSS, and JavaScript on the frontend. The first uncached request creates optimized static files, and later pages reuse them instead of repeating the work.
- Optimize the assets that matterMinify HTML, CSS, and JavaScript independently.
- Keep originals untouchedGenerated files are stored apart from theme and plugin files.
- Control exceptional filesExclude dynamic or incompatible files without turning everything off.
Optimize once, reuse everywhere
It runs by itself once you choose what to optimize.
- 01
Inspect
FVM reads the assets required by the first uncached frontend request.
- 02
Process
Selected HTML, CSS, and JavaScript are minified and written as static cache files.
- 03
Reuse
Pages that need the same asset set reuse the generated files for efficient delivery.
Controls for real WordPress sites
Turn each optimization on or off, and exclude single files.
Selective exclusions
Ignore changing or incompatible files so dynamic URLs do not create unnecessary cache variants.
Local font delivery
Cache external fonts locally and normalize CSS URLs for cleaner delivery.
Automation-ready cache control
Purge FVM caches with WP-CLI for a single site, a multisite URL, or an entire WordPress network.
wp fvm purge
Custom cache paths
Define a public cache directory and URL when your infrastructure needs a custom location.
Cache-layer awareness
Built to coexist with common WordPress page caches and hosting cache-purge workflows.
Add page caching and a broader performance toolkit
WP Raiser builds on the same performance experience with page caching and additional optimization features beyond FVM.
