About the YouTube Thumbnail Resizer

This fits any photo to the exact 1280 × 720 pixel size for a YouTube video thumbnail. Posting an image at the right dimensions means YouTube shows it crisply and doesn't crop or squash it awkwardly. Drop in a picture, choose how it should fill the frame, and download a perfectly-sized image — all in your browser, nothing uploaded.

How it works

Your image is drawn onto a 1280 × 720 canvas at the exact YouTube size. You choose the fit:

Cover — the image fills the whole frame and any overflow is cropped, so there are no borders.
Contain — the entire image fits inside the frame and the empty space is padded with a background colour you pick.

The result downloads as a PNG at exactly 1280 × 720 pixels.

Good to know

The output is a lossless PNG at the exact target size. If your source image is smaller than 1280 × 720, filling the frame means enlarging it, which can look soft — start from an image at least 1280 × 720 pixels for the sharpest result. Platform dimensions change from time to time, so check the current recommended size if it matters.

Privacy

Resizing happens entirely in your browser with the Canvas API. Your image is never uploaded or stored.

Preguntas frecuentes

What size is a YouTube Thumbnail?

The recommended size is 1280 × 720 pixels. This tool outputs exactly that.

Is it free?

Yes — 100% free, no sign-up, no watermark, and nothing uploaded.

Are my images uploaded?

No. Resizing happens in your browser with the Canvas API, so your image never leaves your device.

What's the difference between Cover and Contain?

Cover fills the whole frame and crops the overflow (no borders). Contain fits the entire image inside the frame and pads the rest with your chosen background colour.

Why does my image look soft after resizing?

If the source is smaller than 1280 × 720, filling the frame enlarges it, which softens detail. Start from an image at least 1280 × 720 pixels for a crisp result.

What format do I get?

A PNG at exactly the target dimensions, ready to upload.
