Does resizing happen on a server?

No. Images are resized in your browser with high-quality step-down scaling for crisp results. Nothing is uploaded.

Will resizing keep the aspect ratio?

Yes by default. Enable “maintain aspect ratio” to fit within your target box without distortion, or turn it off to force an exact width and height.

Are there presets for social media?

Yes. There are presets for Instagram, Facebook, X/Twitter, YouTube and LinkedIn, plus common web, avatar and thumbnail sizes.

Can I enlarge images?

Yes, though enlarging cannot add detail that is not there. Downscaling produces the sharpest results.

Can I resize images in bulk?

Yes. Resize many images at once and download them together as a ZIP.

Resize a YouTube thumbnail

Resize any image to YouTube’s 1280×720 thumbnail size without distortion, right in your browser. Fast, private and free.

Privacy-first: every image is processed locally in your browser. Nothing is uploaded, stored or transmitted to any server.

YouTube’s thumbnail rules

YouTube wants thumbnails at 1280×720 (16:9), at least 640px wide, and under 2 MB. Smaller uploads get scaled up and look soft exactly where you need sharpness — thumbnails are rendered tiny in search results, so crispness at small sizes is what wins clicks.

Getting a non-16:9 image to fit

Screenshots and photos are rarely 16:9. Fill mode center-crops to cover the full 1280×720 frame — usually right for photos. Fit mode keeps the whole image and fills the leftover space with a color or a blur, handy for game art or posters where nothing may be cut. The preview shows the exact frame YouTube will receive.

Fast iteration, zero uploads

Thumbnail work is iterative — export, look, tweak, repeat. Because everything renders locally in your browser there is no upload round-trip in the loop, and unpublished video artwork stays on your machine.
