Resize Images to Every YouTube Size
A thumbnail is the single biggest factor in whether someone clicks your video, and YouTube renders it at one exact size: 1280 × 720 pixels in a 16:9 ratio. This tool crops any photo to that thumbnail size — plus channel art, banners, and profile pictures — so every image lands at the dimensions YouTube expects instead of being squeezed or auto-cropped after upload.

How to Resize an Image for YouTube
Pick the YouTube Size
Choose a preset — Thumbnail, Channel Art, Profile Picture, or Banner. The crop frame switches to that exact aspect ratio.
Upload Your Image
Click the upload area or drag and drop a file. JPG, PNG, and WebP are supported.
Position & Zoom
Drag to reposition the image, then scroll the wheel, use the zoom buttons, or pinch on mobile to control exactly what stays in frame.
Download
Export as PNG for the crispest result or JPG for a smaller file, already at the exact YouTube dimensions.

Frequently Asked Questions
What size should a YouTube thumbnail be?
YouTube recommends 1280 × 720 pixels in a 16:9 ratio, with a minimum width of 640 pixels. This matches the video player, so the thumbnail displays full and sharp everywhere it appears. Select the Thumbnail preset (the default) and the crop frame locks to that size.
What is the maximum file size for a YouTube thumbnail?
YouTube caps custom thumbnail uploads at 2 MB. Exporting as JPG produces a much smaller file than PNG, so choose JPG if a detailed photo pushes past the limit; use PNG when you need the crispest text and graphics.
Can I resize a thumbnail without stretching the image?
Yes. The tool never stretches your image — it scales it to cover the 16:9 frame and lets you drag and zoom to choose what stays in view, then crops to the exact size. Nothing is distorted; only the parts outside the frame are trimmed.
What is YouTube Channel Art size?
Channel Art is the large banner at the top of your channel page, recommended at 2560 × 1440 pixels. Because it is cropped differently on phones, desktops, and TVs, keep your logo and channel name in the central safe area so nothing important gets cut off.
Which file formats can I use?
Upload JPG, PNG, or WebP. Download the result as a PNG (lossless, best for text and graphics) or a JPG (smaller file, best for photos). YouTube accepts both for thumbnails.
Are my images uploaded to a server?
No. All cropping happens in your browser on a local canvas, and the finished file is generated on your device. Your images never leave the browser, which keeps unreleased thumbnails and branding private.
Why does my image have a white edge after cropping?
The frame uses a white background. If you zoom out so far that the image no longer covers the whole frame, the empty area shows as white. Zoom in or reposition until the image fills the frame from edge to edge.
