Benefits

The case for compressing every image

Smaller images aren't just nice to have — they're a measurable lift across speed, SEO, and spend.

Pages load faster

Images are usually 50–70% of total page weight. Halving image size often halves load time on real-world connections, especially on mobile.

Better Core Web Vitals

Largest Contentful Paint is almost always an image. Compressing your hero shaves seconds off LCP — a direct Google ranking signal since 2021.

Higher search rankings

Page speed feeds directly into Google’s ranking algorithms. Fast-loading pages outrank slow competitors on identical content.

Lower bounce rate

Google found that bounce probability rises 32% when load time goes from 1s to 3s, and 90% from 1s to 5s. Smaller images keep visitors on the page.

More conversions

Walmart found a 2% conversion lift for every 1s of load-time improvement. Amazon estimates each 100 ms of latency costs them 1% in sales.

Lower bandwidth costs

If you serve images from a CDN or cloud bucket, every megabyte costs money. A 70% reduction in image size means a 70% reduction in egress bills.

Mobile-friendly by default

Most of your traffic is on cellular. Compressed images load reliably on 3G/4G in places where uncompressed assets time out and fail.

Greener emails and ads

Email clients and ad networks impose strict size limits. Compressing keeps creatives under thresholds without sacrificing visual fidelity.

Smaller carbon footprint

Every byte transferred runs through routers, servers, and screens that consume energy. Lighter pages are measurably greener — at scale, by a lot.

Understand

How this compressor works

Most online image compressors upload your file to a server, run a CLI tool like cjpeg, cwebp, or oxipng, and send the result back. We run those exact same encoders — compiled to WebAssembly — directly inside your browser tab. The output is bit-for-bit identical to what the desktop versions produce at the same settings.

Because nothing is uploaded, your photos, screenshots, and product shots stay private. There's no rate limit, no waiting in a server queue, and no cookie banner asking you to accept terms before you can compress a single file. It's the way image compression should have worked all along.
