Steam Event & Announcement Image Resizer
Every update, devlog or sale event on Steam needs a cover image (800 × 450) and ideally a header (1920 × 622). Drop one image, set the focus point, download both. Nothing is uploaded.
| ASSET | SIZE (PX) | WHERE IT SHOWS | REQUIRED |
|---|---|---|---|
| Event cover image | 800 × 450 | Your store page's recent events, event lists, the library page. Links to the event. | Yes |
| Event header image | 1920 × 622 | Top of the event page itself | Optional |
Event image sizes at a glance
Cover image: 800 × 450, required. Shown on your store page, in event lists, the library and wherever Steam features the event next to other games. Keep one clear subject and big shapes: it's often shown at about 300 px wide.
Header image: 1920 × 622, suggested. Shown at the top of the event page. Keep key details away from the left and right edges, which get cropped on narrow screens.
What makes a good event cover
Show the news, not the logo: the new boss, the new map, the "Episode 2" art. If it's a sale, Steam adds the discount badge itself. Post an event at least every few weeks during Early Access or before launch; each one is a free reason for followers to come back to your page.
Questions
▸What size is a Steam event cover image?
800 × 450 pixels (16:9). It's required, and it's the image players see under 'Recent events & announcements' on your store page, in event lists and on the library page.
▸What size is a Steam event header image?
1920 × 622 pixels. It's optional but suggested: it sits at the top of the event page and sets the colours of the detail view.
▸Do I need my logo on the event cover?
No. Steam shows your game's name and icon next to the cover automatically. Use the space for the news itself: the new feature, the sale, the character.
▸Why post events at all?
Events show on your store page, reach followers and wishlisters in their library, and can be featured on Steam. A steady cadence also shows players the game is alive, which matters a lot in Early Access.
