What is How to reduce image size without losing quality?

TL;DR: To shrink an image without visible quality loss: convert to WebP (or JPG for photos), set quality 78–85%, resize the longest side to the max you actually need.

Reducing image size without visible quality loss means using perceptual compression: the human eye can't distinguish small detail at typical viewing distances, so most pixel-perfect detail is wasted bytes.

Three levers matter: format (WebP < JPG < PNG for photos), quality (sweet spot is 78–85%), and resolution (cap longest side at 1920px for web, 1080px for mobile, 800px for thumbnails).

How it works

Step-by-step

Compress your file in under a minute — 100% in your browser.

2

Open Shrink44

Set quality to ~82%

82% is visually indistinguishable from the original for most photos.

Cap longest side

1920px is plenty for desktop, 1080px for mobile, 800px for thumbs.

FAQ

Frequently asked questions

What's the best image format for the web?

WebP is universally supported and 25–35% smaller than JPG. Use JPG as a fallback for photos and PNG for graphics needing transparency.

What quality should I use to keep quality?

82% is the sweet spot for JPG / WebP. Below 70% becomes visible on most images. Above 90% gives diminishing returns.

Should I resize before compressing?

Yes — always cap the resolution to what you actually need. A 4000px image displayed at 800px is 25× more pixels than necessary.
