Why PNG files can cause issues
Large PNG files can be frustrating in email because they increase attachment size and may push messages over file limits. They are often much larger than necessary for simple photo sharing.

PNG vs JPG
PNG keeps more image data and often results in bigger files, while JPG is typically much smaller and more practical for email attachments.
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
