Resize Image to 320×320 px

Resize any image to 320 × 320 pixels — the classic square avatar size, still the default on many forums and comment systems.

How to resize an image to 320×320 px.

The dimensions are already filled in. 320×320 is 1:1 square, so crop to those proportions first if your image is a different shape.

Getting the best results

Crop to a square before resizing

Resizing a rectangular photo to a square either squashes it or crops it arbitrarily. Crop deliberately first — centred on the face for an avatar — so you control what survives.

Check it at the display size

Judge the result at 40 pixels, not at 320. Detail that looks fine full-size often turns to mush at the size the interface actually renders, and a tighter crop usually fixes it.

What 320×320 is for

320 × 320 is one of the oldest surviving avatar sizes on the web. Forum software, comment systems, and Gravatar-style services settled on a small square early on, and plenty of them still serve exactly this.

At a tenth of a megapixel it is deliberately small. The image is displayed at 40 or 80 pixels in most interfaces, so 320 gives you enough headroom for a high-density screen and nothing wasted beyond it.

Where this size is used

Forum and comment avatars, small app icons, Gravatar-style profile services, chat display pictures, and any interface that renders a face in a circle no bigger than a thumbnail.

What to expect

A square crop, so anything not already square will need trimming. At this size fine detail disappears — faces read as recognisable shapes rather than portraits, which is all an avatar needs.

Frequently asked questions.

Everything you need to know about resizing images to 320×320 px.

Yes, for older platforms and anything that displays avatars small. Newer services often want 400 or 512 pixels, so check the specific requirement before settling on this.

Almost always because the crop is too wide. An avatar shown at 40 pixels needs a tight head-and-shoulders crop; a full-body photo reduced to a square becomes an unreadable smudge.

JPEG for a photograph, PNG if it is a logo or has transparency. At 320 × 320 both are small enough that file size is rarely the deciding factor.

No. This resizer runs entirely in your browser using WebAssembly, so the file never leaves your device and the tool keeps working offline once the page has loaded.

This page handles one at a time. For a batch of team photos, resize each here or use the main Image Resizer, then run the set through the Bulk Compressor together.

320×320 px is 1:1 square at 0.1 MP, which prints at about 27 × 27 mm at 300 DPI. Anything not already in that ratio needs cropping first, or it will be stretched.

Scaling down uses Lanczos resampling, the highest-quality algorithm available in the browser, so the result usually looks sharper than the original viewed at the same size. Scaling up cannot add detail that was never captured.
