Resize images to YouTube thumbnail size (1280×720)
Turn any image into a 1280×720 YouTube thumbnail under the 2 MB limit, cropped or fitted to 16:9. It runs in your browser in seconds — nothing is uploaded.
Your files stay on your device: they are processed in this browser tab’s memory and never uploaded.
YouTube’s thumbnail rules
YouTube recommends 1280×720 pixels (16:9), at least 640 pixels wide, as JPG, PNG or GIF and under 2 MB. The resizer applies all of these automatically.
Stay under 2 MB
With the target size set to 2 MB, the tool picks the highest JPG quality that still passes YouTube’s limit.
FAQ
Can I use a vertical image?
Yes — choose Fit to keep it whole on a coloured background, or Crop to fill the 16:9 frame.
PNG or JPG?
JPG keeps you safely under 2 MB; PNG is fine for simple graphics.
Who needs an image compressor and resizer?
Website owners compress images to speed up pages and pass Core Web Vitals, job seekers and students squeeze photos under strict upload limits, online sellers resize product shots to marketplace dimensions, social media managers crop the same picture to Instagram portrait, Story and X header sizes in one go, YouTubers fit thumbnails to 1280×720 under 2 MB, and video editors downscale stills and textures before importing them so projects stay light.
