Key Differences from Chrome Web Store
- Edge allows up to 10 screenshots vs. Chrome's 5 per language.
- Edge has a 75-character name limit vs. Chrome's 45 characters.
- Edge has a separate "short description" field (132 chars) — Chrome uses the summary differently.
- Edge description allows up to 16,384 characters — Chrome caps at 16,000.
- Image dimensions and formats are otherwise identical, since both stores serve Chromium extensions.
- You can reuse the same icons, screenshots, and promo images on both stores.
Create assets once, publish on both Chrome and Edge. CWS Kit generates all the sizes both stores need.
