Resize an image to 600x600 for a profile or listing photo

When to reach for 600x600

600x600 is a 1:1 square with more room than a small avatar, which suits a larger profile photo or a marketplace listing image. The extra pixels let a buyer or visitor make out detail without the file getting heavy.

It is a good middle ground when a small thumbnail looks soft but a full-resolution upload is overkill. The resize tool is set to 600 by 600.

Crop the source square first

Listing photos and portraits usually come out rectangular, so dropping one straight into 600x600 stretches it. Crop to a 1:1 square first, then resize so the item or face keeps its real proportions.

For a marketplace photo, fill the square with the product and keep it centered. A tight, centered crop reads better in a grid of listings than a small item floating in empty space.

Keep the listing image quick to load

Marketplace pages show many photos at once, so a lighter file helps the page feel snappy. After resizing, compress the result to shrink the file without touching the dimensions.

Everything runs locally in your browser. A listing photo or personal headshot is processed on your device and never sent to a server.

Check the marketplace minimum before you settle on 600

600x600 is a tidy square, but several marketplaces set a minimum longest edge above it, and some gate their zoom feature behind a larger size. Uploading a 600 px square to a platform that wants more gets you either a rejection or a listing with no zoom.

Check the requirement for where you are selling before you commit. The Etsy listing photo size and eBay photo size pages cover what each platform asks for. Use 600x600 for avatars and internal thumbnails, and size up when a marketplace asks you to.
