How to compress JPEG without losing quality
JPEG is the most common photo format online. The trick is balancing quality percentage, dimensions, and output format so files are smaller but still look sharp.
1. Start with the right quality setting
For photographs, 75%–85% quality is usually the sweet spot. Below 70%, banding and blur appear in skies and skin tones. Above 90%, file size savings are minimal.
2. Resize before you compress
A 4000px-wide camera JPEG displayed at 800px on a blog wastes pixels and kilobytes. Set max width to your real display size (e.g. 1920px for full-width heroes, 1200px for articles).
3. Consider WebP or AVIF for the web
Converting JPEG to WebP or AVIF often cuts file size 25–50% at similar visual quality. Keep JPEG for email attachments when compatibility matters.
4. Compare before you download
Use a before/after preview so you can spot artifacts before publishing. NexusCompress runs entirely in your browser — images are never uploaded to a server.
