Understanding KB and MB When Preparing Images for Amazon Product Images
Size limits are written in kilobytes and megabytes, and the units trip people up. Marketplace images need enough resolution for zoom while still uploading reliably through seller tools.
Recommended settings for Amazon product images
| Setting | Starting point |
|---|---|
| Format | JPEG (WebP where accepted) |
| Width | about 2000 px on the long edge |
| Quality | 78 |
| File size | 500 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 Amazon product images, a target of 500 KB is a comfortable default. Our results panel shows the exact size of each compressed file so you can confirm it before uploading.
Step by step with TheCompressJPEG
- Open the compress JPEG to 500 KB tool, or the main compressor for custom settings.
- Drop in your image. Nothing is uploaded; it is processed in your browser.
- Set the maximum width to 2000 and the target size to 500 KB.
- Press Compress, check the result and download it.
Quick tips
- Use WebP where it is supported and you control the page.
- Never re-compress an already compressed JPEG if you can avoid it.
- Strip metadata from images you share publicly.
- Always keep the original file and compress a copy.

Wrapping up
For Amazon product images, the reliable recipe is simple: resize to around 2000 pixels, compress at quality 78 or to a 500 KB target, and check the result before you upload. Keep the original so you can always start again.
