What do your pictures cost on a phone?

Paste a page address. You get every picture the page loads — type, size, the code around it — with how long each takes on a slow phone connection, how much of the 2.5 seconds Google allows for the main picture (the "LCP" target) it uses up, and a labelled estimate of what it would shrink to. Convert the ones that matter with one click for the real numbers and the code to paste.

This page needs JavaScript to call the API. Without it: GET /api/v1/audit?url=https://your-page returns the same report as JSON, and the converter works on files you already have.

Page address (https, public)

Unlike the converter, this sends the address to our API, which fetches the page and the pictures it references (up to 20, 4.5 MB each), analyses them and keeps nothing — no copies, no log of the address. Where a picture comes in several sizes, the one a phone would download is checked. Pictures set from CSS in the page itself are included; ones set in separate stylesheets or added by scripts are not seen. Times are for one download each on a slow phone connection (Google's page-speed test profile, Slow 4G: 1.6 Mbps, 150 ms); "est." values come from our field tests, not from converting your file. Fixed something? Check the same address again: this browser remembers your last result (on this device only) and shows what changed.
