Understanding KB and MB When Preparing Images for Etsy Listings

Updated February 19, 2026 · 7 min read

Size limits are written in kilobytes and megabytes, and the units trip people up. Buyers zoom into listing photos, so the goal is the smallest file that still looks sharp at full size.

Recommended settings for Etsy listings

SettingStarting point
FormatJPEG (WebP where accepted)
Widthabout 2000 px on the long edge
Quality78
File size300 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 Etsy listings, a target of 300 KB is a comfortable default. Our results panel shows the exact size of each compressed file so you can confirm it before uploading.

  1. Open the compress JPEG to 300 KB tool, or the main compressor for custom settings.

  • Write a size limit slightly below the stated maximum to leave a margin.
