BMP vs PNG
BMP produces large files, while PNG offers lossless compression with smaller file sizes. PNG is more efficient and widely supported.
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
- PNG files are often larger than JPG/WebP. Use PNG when you need transparency or lossless output.
