Common Mistakes When Compressing Images for Pinterest Pins

Updated September 6, 2026 · 6 min read

A few habits cause most of the blurry or oversized images we see. Pins are tall and browsed in dense grids, so file size adds up quickly across a board.

Recommended settings for Pinterest pins

SettingStarting point
FormatJPEG (WebP where accepted)
Widthabout 1000 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.

Common Mistakes When Compressing Images

Compressing the same JPEG again and again stacks artefacts each time, so always work from the original. Setting quality very low on a huge image gives a small file that looks muddy; resizing first is better.

Another mistake is ignoring orientation. Phones store rotation in metadata, and some tools drop it, leaving sideways photos. Our tool applies the correct orientation before compressing, so what you see is what you get for Pinterest pins.
