Understanding KB and MB When Preparing Images for Shopify Product Photos
Size limits are written in kilobytes and megabytes, and the units trip people up. Product grids show many images at once, and lighter photos keep collection pages quick on mobile shoppers' phones.
Recommended settings for Shopify product photos
| Setting | Starting point |
|---|---|
| Format | JPEG (WebP where accepted) |
| Width | about 2048 px on the long edge |
| Quality | 78 |
| File size | 200 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 Shopify product photos, a target of 200 KB is a comfortable default. Our results panel shows the exact size of each compressed file so you can confirm it before uploading.
