Overview
ArtSites accepts image uploads in several formats with specific size and dimension requirements. Following these guidelines ensures your artwork displays correctly.
Supported Formats

Size Limits
| Limit | Value |

| Maximum file size | 50 MB |
If you start an upload and then leave it sitting for more than 10 minutes before it finishes, it may fail and you'll need to start it again.
Recommended Image Dimensions
- Minimum: 1200px on the longest edge
- Recommended: 2000-4000px on the longest edge
- Maximum: No hard limit, but very large files take longer to upload and process
ArtSites automatically generates responsive sizes from your uploaded image, so uploading a high-resolution original gives the best results across all devices.
Tips
- JPEG at 85-90% quality provides a good balance of file size and visual quality
- Avoid uploading images smaller than 1200px; they may appear blurry on high-resolution screens
- If an upload fails, check your file size and internet connection first
- ArtSites preserves the full-resolution original and creates optimized versions automatically
