Image compression for agencies — every client site, fast by default.
Standardize image optimization across every account you manage, regardless of what CMS or host each client runs, without paying per seat or per client.
The usual stack
With pre-compressed uploads
Underperforming sites are the ghost in every churn conversation.
When an agency scales from five client accounts to fifty, the informal habits that worked at small volume stop working. Image optimization is one of the first things to slip: a new account gets onboarded, campaigns go live, and nobody runs the basic technical check — format, compression, lazy loading — before the ad spend starts flowing. Months later, cost-per-lead has crept up and a client is asking hard questions. Performance issues that were never diagnosed become the quiet reason accounts churn, and because every client runs a different CMS and hosting setup, there's rarely one standardized way to fix it across the whole roster.
One step, every account, before anything goes live.
Add it to onboarding
Run every new client's image assets through FastCompressor as part of the standard technical audit, before the first campaign launches.
Batch by client folder
Keep each account's assets separate and compress them in one pass, whether it's five images or five hundred.
Export the format each platform wants
WebP for a Shopify or WordPress client, optimized JPG for a platform with less flexible format support — the same tool covers both.
Re-run it quarterly across the roster
Add it to the same standardized scorecard you already use for Core Web Vitals reviews.
The features agencies actually use.
Works across every client's stack
Same tool whether the account runs Shopify, WordPress, Webflow, or something custom — no per-CMS plugin to install and maintain.
One license, unlimited accounts
No per-seat or per-client subscription creeping up as your roster grows.
Fast enough for onboarding
Quick enough to run as a standard step in every new client's technical audit, not a separate project.
Batch by folder, not by mix-up
Process one client's assets at a time so nothing from Account A ends up in Account B's export.

Speed improvements show up in numbers clients understand.
In a widely cited case study, a 31% improvement in LCP score correlated with an 8% increase in sales for Vodafone. That's the kind of before-and-after number that turns a routine performance fix into a renewal conversation, instead of a churn one.
One tool, every account on the roster.
FastCompressor Pro removes batch limits and runs as a desktop app, so your whole team can standardize image optimization across every client without adding a line item per account.
