Why HEIC files can cause issues

HEIC vs JPG
HEIC is space-efficient, but JPG is the more universal format for email attachments. JPG works more reliably across mail clients, phones, and desktop apps.
Compression Presets
Presets automatically adjust compression and image size depending on how the image will be used.
| Preset | Compression | Max Dimensions | Typical File Size | Best For |
|---|---|---|---|---|
| Web | Medium | 1920px | 200KB – 800KB | Websites, blogs, landing pages |
| Social | Medium-High | 1200px | 100KB – 400KB | Instagram, Facebook, LinkedIn |
| High | 1200px | 50KB – 200KB | Email attachments and quick sharing | |
| Low (Highest Quality) | No resize | 1MB+ | Printing photos or marketing materials |
Actual file size depends on the original image resolution and format.
Common pitfalls
- JPG does not support transparency. Transparent areas may become a solid color.
- JPG is lossy. For sharp logos/text, consider PNG.
- HEIC conversion requires a local decoder (Phase 2). If it fails today, HEIC support is coming soon.
