How Much Can You Compress a JPEG for Marketplace Ads?
The honest answer is: more than you think. Classified and marketplace ads benefit from several quick-loading photos rather than one slow, heavy one.
Recommended settings for marketplace ads
| Setting | Starting point |
|---|---|
| Format | JPEG (WebP where accepted) |
| Width | about 1600 px on the long edge |
| Quality | 78 |
| File size | 300 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 300 KB or less at 1600 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 marketplace ads.
