Images
Format, size, and composition rules for cover images and screenshots.
Standards#
- Formats: JPG, PNG, or WebP.
- Max file size: 5 MB per image.
- Cover image: recommended around 1200×630 — it is used both as the gallery card and the app page hero.
- Screenshots: any reasonable aspect ratio, up to 4 per app.
Cover image#
The cover is the only thing most users see before they click. It is cropped to different aspect ratios on the card and the hero, so keep the important content away from the edges and don't put small text near the border.
Show the app's real output. A screenshot of the actual result outperforms an abstract graphic every time.
Screenshots#
Use screenshots to answer the questions the description can't:
- What the interface looks like.
- What a real input looks like.
- What a real output looks like.
- Anything unusual about the workflow.
Crop out browser chrome, desktop backgrounds, and personal data. Screenshots containing another person's private information will be rejected.
Warning
Uploaded files must be what they claim to be. Files that attempt to exploit the upload handling are treated as a Terms violation.
