Converting HEIC to JPEG for Landing Pages
iPhones save photos as HEIC by default, and not every site accepts it. 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.
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 150 KB for landing pages. JPEG is accepted almost everywhere.

Quick tips
