Compress images before they ever hit your build.
A local, scriptable-feeling way to shrink assets before they reach your repo — no cloud API key, no rate limit, no config file to maintain.
Faster load

Same zoom-in detail for fabric and stitching — a fraction of the file size Shopify stores and serves.
Lighthouse doesn't care that you meant to fix it later.
You export a hero image from Figma, drop it in, push to production, and Lighthouse comes back red because that asset is 4.2 MB. Build-time image optimization tools help once something's already in your CI/CD pipeline, but they don't help when you're prepping assets locally, writing a blog post, fixing a client site outside the main repo, or just don't want to wire up another pipeline step for a one-off task. CLI tools like ImageMagick or Sharp work, but you have to remember the right flags every time. Cloud-based compressors mean an upload, an API key, and often a rate limit right when you need to move fast.
The step before the pipeline, not a replacement for it.
Export or gather your assets
Figma exports, screenshots, stock photos, whatever's about to go into a component, a blog post, or a one-off page.
Drop them into FastCompressor
Runs locally, no API key, no rate limit, no sign-up. Batch a whole assets folder in one pass.
Get predictable, web-ready output
WebP or optimized JPG at the size you'd want to commit, without waiting on a build step to catch it.
Commit already-optimized assets
Your Lighthouse and Core Web Vitals checks pass without asking your CI pipeline to do the heavy lifting.
The features developers actually use.
Fully local processing
No cloud API key to manage, no rate limit to hit mid-sprint, no dependency to add to a project just to compress a folder.
Handles what your pipeline doesn't
Great for assets that never touch a build step at all — blog posts, docs, marketing pages, client one-offs.
Same settings, every batch
Consistent quality and format across a whole folder, so output doesn't vary asset to asset.
Zero config to maintain
No YAML to write, no build plugin to keep updated across dependency bumps.

Most sites still fail the metrics that matter.
Only about 47% of sites currently meet all three Core Web Vitals thresholds — LCP, INP, and CLS — and the rest lose an estimated 8–35% in conversions and revenue to performance issues. Oversized images are one of the most common, and most fixable, reasons a site misses that bar.
No API key. No rate limit. No config.
FastCompressor Pro removes batch limits and runs as a desktop app, so it's just as fast for one asset as it is for an entire repo's worth.
