About this tool

1280 x 720 pixels is what YouTube Thumbnail needs: landscape, 16:9, 0.9 megapixels. Upload anything and it comes back cropped to fit. YouTube displays thumbnails as small as 210 pixels wide in search, so keep any text large and away from the bottom-right, where the duration badge sits. YouTube compresses thumbnails hard, so flat colour and heavy type survive the trip where fine detail and gradients do not. Nothing is uploaded. The resize happens on your own device, so the file never reaches a server and it keeps working offline once the page has loaded. Cropping to 16:9 from another shape removes part of the image by definition. The preview makes that visible before you download rather than after.

How to use this tool

  1. Drop your image inAny JPG, PNG or WebP. Nothing is uploaded - your browser reads the file directly.
  2. It resizes to 1280 x 720 pixelsThe YouTube Thumbnail preset is already selected on this page, so there is nothing to type in.
  3. Check the preview and downloadThe preview shows the exact crop. Reposition if you need to, then save as JPG, PNG or WebP.

Key features

  • No limit on how many images you resize.
  • Resizes to exactly 1280 x 720 pixels, the current YouTube Thumbnail size.
  • Runs in your browser - no upload, no account, no watermark.
  • Export as JPG, PNG or WebP, whichever the platform prefers.
  • Live preview, so you see the crop before downloading instead of after.

Common uses

  • Creators making a thumbnail before publishing a video.
  • Getting a correctly sized image without opening a full editor for a 30-second job.
  • Preparing a batch at 1280 x 720 pixels before a scheduled post.
  • Fixing an image a platform rejected for being the wrong dimensions.
  • Resizing on a phone without installing an editing app.

Tips for better results

  • PNG keeps text and sharp edges crisp at this size; JPG is smaller for photographs.
  • Crop to 16:9 before resizing when the subject matters - then you choose what is lost rather than the tool.
  • Start from the largest original you have. Scaling up to 1280 x 720 pixels from something smaller looks soft, and nothing undoes that.
  • YouTube compresses thumbnails hard, so flat colour and heavy type survive the trip where fine detail and gradients do not.

Mistakes to avoid

  • Assuming another platform at the same pixel size behaves identically. YouTube compresses thumbnails hard, so flat colour and heavy type survive the trip where fine detail and gradients do not.
  • Re-saving the same JPG over and over. Each save loses a little more detail, permanently.
  • Letting the image stretch instead of keeping the ratio. A squashed face is more obvious than a tight crop.
  • Putting important detail near the edges of a 16:9 frame. Platforms crop again for thumbnails and previews.
