How Much Can You Compress a JPEG for DSLR Photos?
The honest answer is: more than you think. 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.
How Much Can You Compress a JPEG
A typical phone photo of 3 to 5 MB can usually drop to 1000 KB or less at 3000 pixels wide with no visible problem at normal viewing size.
The limit is reached when artefacts appear: blocky skies, haloes around edges or smeared fine textures. Stop one step before that for DSLR photos.
