Thumbnail checklist
- 1280 × 720 px, 16:9.
- Under 2 MB — choose JPG at 85–90% quality.
- Big, readable text and a clear face or object.
Quick answers
Why 1280×720?
It's YouTube's recommended size; smaller images look blurry on TVs and large screens.
What makes it better than a basic resizer
- Focal point: click the face or product once and every crop — square, story, banner — keeps it in frame.
- Blurred-background fit: show the whole photo in a different shape without black bars, like Instagram does.
- Safe zones: see which parts of a Story, Reel or TikTok are hidden behind the app's buttons before you post.
- 17 sizes, one ZIP: named by platform and size, ready to schedule.
- Private: everything happens in your browser.
Frequently asked questions
Are these the official sizes?
They're the sizes each platform recommends for upload as of 2026. Platforms change layouts often, so check their help pages for new formats.
JPG, PNG or WebP?
JPG for photos (smallest), PNG for graphics with text or transparency, WebP for websites.
Will it upscale small images?
Yes, if a size is larger than your original, but upscaled images look softer. Start with the largest original you have.
