Resize Images for Steam
Steam has a different required size for almost every asset on the platform — and they're not always obvious. Profile avatars, artwork showcases, workshop thumbnails, game capsules — each one has its own dimensions, and uploading the wrong size either gets rejected outright or results in a stretched, blurry mess in the Steam UI. The tool below handles the resizing automatically once you pick your asset type.

The problem
Steam's image requirements are scattered and inconsistently documented. The profile avatar needs to be 184×184 px, but the mini-profile background that shows on hover is 448×184 px — a completely different ratio. Artwork showcase images are 506×253 px, which is an unusual 2:1 ratio most people don't set up their canvases for. Workshop item thumbnails need to be exactly 512×512 px square.
Upload the wrong dimensions and one of two things happens: Steam rejects the upload with a vague error, or it accepts it and distorts the image to fit. Neither is what you want, especially if you're publishing a workshop item or setting up a game page where presentation matters.
How it works
- Open the tool and select the Steam asset type from the list.
- Drop your image — the tool immediately shows a preview at the correct target dimensions.
- Adjust the crop area if your image isn't the right aspect ratio. You control which part gets kept.
- Download the resized file. No upload, no account, no waiting — runs entirely in your browser.
Why I built it
Setting up workshop items and profile artwork repeatedly meant looking up the correct dimensions every single time. Steam's own help docs aren't always up to date, and the sizes are spread across multiple support articles. I wanted one page with a complete reference and a tool that handles the resize in the same place.
Steam image dimensions reference
All required or recommended dimensions for Steam assets, current as of 2026:
| Asset | Dimensions | Notes |
|---|---|---|
| Profile avatar | 184×184 px | Displays as circle crop |
| Animated avatar | 184×184 px | GIF or APNG, Level 10+ required |
| Profile background | 1920×1080 px | Full-page behind profile |
| Mini profile background | 448×184 px | Hover card background |
| Artwork showcase | 506×253 px | 16:9 aspect ratio recommended |
| Workshop thumbnail | 512×512 px | Square, shows in search results |
| Screenshot | 1920×1080 px | Matches most display resolutions |
| Game capsule | 460×215 px | Store page thumbnail |
| Header capsule | 460×215 px | Library grid view tile |
Note: animated avatars require Steam Level 10 or higher. Profile backgrounds are visible to anyone who views your profile. Workshop thumbnails are the first thing people see when browsing, so a clean 512×512 image is worth getting right.
