Why Your Images Are Too Large for DSLR Photos
If an upload keeps failing, the image is usually larger than it needs to be in more ways than one. Camera JPEGs straight off the card can be many megabytes each, which is heavy for sharing or web use.
Recommended settings for DSLR photos
| Setting | Starting point |
|---|---|
| Format | JPEG (WebP where accepted) |
| Width | about 3000 px on the long edge |
| Quality | 85 |
| File size | 1000 KB or less |
These are practical defaults. If the platform or form you are using publishes its own limits, follow those instead.
Why Your Images Are Too Large
Modern cameras capture 12 to 50 megapixels. That detail is useful for printing posters but rarely for DSLR photos, where about 3000 pixels wide is plenty.
Metadata, PNG format for photos, and maximum-quality saves also add weight. Re-encoding as JPEG at quality 85 after resizing solves all three at once.
