Compressing images without visibly hurting quality
Why image weight matters
Images are the largest part of most web pages, so compressing them is the single most effective way to improve load time and Core Web Vitals. It also matters for forms with a size cap, email attachments, and storage.
How the compressor decides what to remove
For JPG and WebP it re-encodes at a quality level tuned so the change is invisible at normal viewing size, while cutting file size substantially. For PNG it reduces the colour palette where an image does not need thousands of colours and strips metadata. Dimensions are preserved — the image looks the same, it just weighs less.
Get more out of it
- Resize first: if an image will display at 800 px, scale it to 800 px before compressing. This alone often removes 80% of the bytes.
- Pick the right format: photos as JPG or WebP, graphics and screenshots as PNG or WebP.
- Compress once: repeatedly re-compressing a JPG slowly degrades it. Keep an original.
Hitting an upload limit (20 KB, 50 KB, 100 KB, 200 KB)
Government and exam portals often cap photos and signatures at small sizes. Compress, check the result, and if you are still over, reduce the image dimensions and try again. A passport-style photo can usually reach 20–50 KB by combining a modest resize with compression.
