Color Profiles and sRGB for Landing Pages
Colours that look vivid on your camera can look dull after upload if profiles are mishandled. Landing pages live or die by load speed, and images are usually the heaviest part of them.
Recommended settings for landing pages
| Setting | Starting point |
|---|---|
| Format | JPEG (WebP where accepted) |
| Width | about 1600 px on the long edge |
| Quality | 70 |
| File size | 150 KB or less |
These are practical defaults. If the platform or form you are using publishes its own limits, follow those instead.
Color Profiles and sRGB
Most screens and browsers assume sRGB. Photos in wider profiles may shift when the profile is dropped during upload.
Browser-based compression outputs standard sRGB pixels, which is what landing pages expects. If colours change dramatically, export from your editor in sRGB before compressing.
