Every platform wants a different size, and every platform crops your photo when you get it wrong — usually across the face. YouTube thumbnails are 1280×720, Facebook covers are 820×312, Twitter headers are 1500×500, Instagram squares are 1080×1080, and a WhatsApp DP is 640×640. Guessing any of them wastes a post.

Pick the platform, pick the fit: “crop to fill” cuts the photo to the exact shape with no empty space (best when the subject is centred), while “pad to fit” shrinks the whole photo inside the frame with a coloured pad — the no-crop look that never cuts anything off. The preview shows the exact result before you download.

For free-form sizes instead of platform presets, use the image resizer — exact pixels or percentage, with aspect-ratio lock.

Frequently asked questions

YouTube Thumbnail 1280×720, Facebook Cover 820×312, Twitter/X Header 1500×500, Instagram Square 1080×1080, WhatsApp DP 640×640.
Crop to fill or pad to fit?
Crop to fill cuts the photo to the exact shape (best for centred subjects). Pad to fit shrinks the whole photo inside the frame with a coloured pad, so nothing is cut off.
