Lossy vs Lossless Compression for Amazon Product Images

Updated May 10, 2026 · 9 min read

Image compression comes in two flavours. Marketplace images need enough resolution for zoom while still uploading reliably through seller tools.

Recommended settings for Amazon product images

SettingStarting point
FormatJPEG (WebP where accepted)
Widthabout 2000 px on the long edge
Quality78
File size500 KB or less

These are practical defaults. If the platform or form you are using publishes its own limits, follow those instead.

Lossy vs Lossless Compression

Lossless compression, as in PNG, keeps every pixel exactly and saves modest space. Lossy compression, as in JPEG and WebP, discards detail the eye barely notices and saves far more.

For photographs used for Amazon product images, lossy is the practical choice. Save lossless formats for graphics where every pixel edge matters.

  • Always keep the original file and compress a copy.

FAQ

How do I compress many images for e-learning courses at once?

Drop all of them into the tool together and use Download all to get a single ZIP.

What JPEG quality should I use for e-learning courses?

Quality around 78 keeps photos looking natural while cutting file size substantially.

Will compressing reduce image quality for e-learning courses?

Some detail is removed, but at sensible settings the difference is not visible at normal viewing size.

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.
