Converting HEIC to JPEG for Instagram Posts
iPhones save photos as HEIC by default, and not every site accepts it. 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.
Converting HEIC to JPEG
When you pick photos through the browser file picker, iOS usually converts them to JPEG automatically. On other systems, open the HEIC in your photo app and export as JPEG.
Once you have a JPEG, compress it to around 500 KB for Instagram posts. JPEG is accepted almost everywhere.
