Redimensionner une Image pour YouTube

Q: What is the best image size for YouTube thumbnails and banners in 2026?

For YouTube video thumbnails, the ideal resolution is 1280 × 720 px (16:9 aspect ratio) with a minimum width of 640 px and file size strictly under 2MB. For channel banners, use 2560 × 1440 px with essential text centered in the 1232 × 338 px safe area. For YouTube Shorts, use 1080 × 1920 px (9:16), and for profile avatars use 800 × 800 px.

Q: Why won't YouTube accept my thumbnail upload?

YouTube enforces a strict 2MB maximum file size ceiling and accepts only JPG, PNG, or GIF formats. If your image exceeds 2MB or uses an unsupported color profile, YouTube's upload pipeline rejects it immediately. Our in-browser resizer allows you to set target file sizes (e.g., 1.5MB) to guarantee instant upload acceptance.

Q: How do I ensure my YouTube banner looks good across Mobile, Desktop, and TV?

YouTube displays channel art dynamically depending on the viewer's device. TVs display the entire 2560 × 1440 px canvas, desktops show 2560 × 423 px, and mobile devices crop down to the central 1232 × 338 px safe zone. Always place channel names, upload schedules, and social links within this central safe zone.

Q: Should I upload PNG or JPEG for YouTube thumbnails?

PNG is recommended for thumbnails with heavy text, bold typography, logos, and digital illustrations because it avoids compression haloing. JPEG (sRGB) is recommended for complex real-world photography and gaming screenshots to keep file sizes easily below the 2MB threshold without visual artifacts.

Q: Are my YouTube images uploaded or stored on any server?

No. Image Resizer Studio operates 100% client-side inside your browser via the HTML5 Canvas API. Your images never leave your device and are never sent to or stored on any remote cloud server.
