Color Profiles and sRGB for Instagram Posts
Colours that look vivid on your camera can look dull after upload if profiles are mishandled. Feed images are displayed at a fixed width, so anything far larger than that is extra weight the platform will resample anyway.
Recommended settings for Instagram posts
| Setting | Starting point |
|---|---|
| Format | JPEG (WebP where accepted) |
| Width | about 1080 px on the long edge |
| Quality | 78 |
| File size | 500 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 Instagram posts expects. If colours change dramatically, export from your editor in sRGB before compressing.
Step by step with TheCompressJPEG
- Open the compress JPEG to 500 KB tool, or the main compressor for custom settings.

- Set the maximum width to 1080 and the target size to 500 KB.
- Press Compress, check the result and download it.
Quick tips
- Write a size limit slightly below the stated maximum to leave a margin.
- Process private images locally rather than uploading them to unknown servers.
- Crop out distractions so pixels go to the subject.
- Use WebP where it is supported and you control the page.

Wrapping up
