How to compress images without losing visible quality
A practical guide to picking the right format, quality level and dimensions so your pages load fast and still look sharp.

Start with the right format
Format choice matters more than the quality slider. WebP typically produces files 25–35% smaller than JPEG at the same perceived quality, and it is supported by every modern browser.
Use PNG only when you genuinely need lossless output or transparency — logos, screenshots with text, and UI assets.
Resize before you compress
Shipping a 4000px photo into a 800px container wastes bandwidth no compressor can recover. Resize to roughly twice the display width to cover high-DPI screens, then compress.
Find the quality sweet spot
For photographic content, quality between 65 and 80 is usually indistinguishable from the original at normal viewing distance while cutting file size dramatically.
Always compare side by side before committing — our Image Compressor shows original and result together with the exact size saved.
