Understanding KB and MB When Preparing Images for DSLR Photos
Size limits are written in kilobytes and megabytes, and the units trip people up. 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.
Understanding KB and MB When Preparing Images
One megabyte is roughly 1000 kilobytes, and some systems count 1024. If a limit says 100 KB, aim a little under, such as 95 KB, to be safe.
For DSLR photos, a target of 1000 KB is a comfortable default. Our results panel shows the exact size of each compressed file so you can confirm it before uploading.

- Always keep the original file and compress a copy.

Wrapping up
For DSLR photos, the reliable recipe is simple: resize to around 3000 pixels, compress at quality 85 or to a 1000 KB target, and check the result before you upload. Keep the original so you can always start again.
