JPEG vs PNG for eBay Listings

Updated March 10, 2026 · 8 min read

Choosing the wrong format can make a file five times larger than it needs to be. Listings with clear, fast-loading photos make it easier for buyers to compare items quickly.

Recommended settings for eBay listings

SettingStarting point
FormatJPEG (WebP where accepted)
Widthabout 1600 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.

JPEG vs PNG

JPEG is built for photographs with smooth gradients and noise. PNG is built for flat colours, sharp text and transparency. Saving a photo as PNG usually produces a much bigger file with no visible benefit.

For eBay listings, use JPEG for photos and PNG only for logos, screenshots with lots of text, or images that need a transparent background. You can convert a PNG photo to JPEG here and often cut its size dramatically.

Quick tips

  • Write a size limit slightly below the stated maximum to leave a margin.
  • Process private images locally rather than uploading them to unknown servers.
  • Crop out distractions so pixels go to the subject.
  • Use WebP where it is supported and you control the page.

A practical default is about 1600 pixels wide and 200 KB or less, unless the destination states its own limits.

Wrapping up
