A thumbnail, a channel banner and a profile picture are three small images with strict rules. YouTube recommends a 16:9 thumbnail at 1280 by 720 pixels under 2 MB, channel art at 2560 by 1440 pixels with your important content inside a centre safe area, and a square profile picture that gets cropped to a circle.
These tools resize, crop and compress to those targets, show you the safe area before you export, and cut a subject out of its background when you want a clean thumbnail. Like everything on this site they run in your browser, so your images are not uploaded. The background remover downloads a small open-source model the first time you use it and runs it locally.
What each tool does
YouTube Thumbnail Resizer
Drop in an image and get a 1280 by 720 thumbnail under the 2 MB limit. Choose crop to fill or fit with a blurred background, move the crop, and download a JPG or PNG. Runs in your browser.
YouTube Banner Resizer
Resize any image into YouTube channel art. A guide shows the centre safe area that appears on every device, so your name and logo are never cropped. Runs in your browser.
Channel Profile Picture Maker
Drag your photo inside a circle preview, zoom, add a coloured ring and a background, and export a square picture for your YouTube channel icon.
Background Remover
Remove the background from a portrait photo and download a transparent PNG. Use it to place yourself on a bold thumbnail background. A small open model downloads once and runs on your device.
FAQ
What size should a YouTube thumbnail be?
YouTube recommends 1280 by 720 pixels (16:9) with a minimum width of 640 pixels and a file size under 2 MB. The thumbnail resizer produces exactly that.
What size is YouTube channel art?
Upload 2560 by 1440 pixels, keep the file under 6 MB, and put your name and logo inside the centre safe area of 1546 by 423 pixels so they show on every device.
Are my images uploaded?
No. Images are resized in your browser. The background remover downloads a small open model once and runs it on your device.
Does YouTube let everyone upload custom thumbnails?
Custom thumbnails need a verified YouTube account. If the option is missing, verify your channel first.
