Compress a photo for the web

Optimise images for fast-loading pages — smaller files, better Core Web Vitals — free, and processed on your device.

Large images are the most common cause of slow web pages. Compressing your photos — or converting them to WEBP — cuts their file size dramatically, which speeds up load times, improves Core Web Vitals and helps SEO, all without a visible drop in quality.

This runs in your browser, so you can optimise a whole gallery for free without uploading anything or paying per image.

Frequently asked questions

What's the best format for web images?

WEBP for most photos and graphics — it's smaller than JPG and PNG at the same quality and is supported by every modern browser. Use the converter to switch, then compress.

How much should I compress web images?

Enough that they look clean but load fast — often 100–300KB for large photos. Balance the quality slider against the file size the tool shows.

Is anything uploaded?

No. All optimisation happens in your browser, so your images stay on your device.
