Resize Image for YouTube

Crop and resize images for YouTube thumbnails, channel banners, profile pictures, and watermarks in your browser.

YouTube uses several very different image frames across a channel: wide video thumbnails, a responsive channel banner, a square profile picture, and a small video watermark. This tool includes each common placement. Choose one, position the aspect-locked crop box, and export an exact-size image without distorting the source.

How it works

1. Add your thumbnail image

Whether it began as a video screenshot, a talking-head selfie, or an exported design mockup, get it onto the panel above with a drag, a tap through your device's file browser, or a clipboard paste. None of that source material needs to already be the right shape — the tool sorts out the proportions in the next step regardless of what you started with. The image loads immediately in your browser, with the file staying on your device the entire time so you can see right away how much letterboxing the resize will need.

2. Choose a YouTube placement and frame it

Choose Video thumbnail, Channel banner, Profile picture, or Video watermark in the Presets tab. The crop box changes shape immediately while the same source remains on stage. Move the box over the area you want to keep, then press Apply Resize to export that placement's exact pixel dimensions.

3. Download and upload to YouTube

Once the preview shows a clean 1280 by 720 frame, hit Download to save the file to your device, then upload it directly as your video's custom thumbnail. Because the dimensions already match what YouTube expects exactly, the platform won't need to stretch or reposition anything on its end, so the thumbnail displays exactly as you framed it in search results, suggested videos, and on your channel page alike. This also means text or a face placed deliberately near an edge stays exactly where you put it instead of being trimmed by an automatic crop after upload.

Frequently asked questions

Does my thumbnail have to be exactly 1280x720?
YouTube accepts other sizes and will scale them, but matching 1280 by 720 exactly avoids any unexpected stretching or cropping once it's live on the platform.
What if my source photo isn't a 16:9 shape?
Move the locked crop box to choose which part of the source fills the 16:9 frame. This avoids letterboxing and avoids stretching the image.
Can I use a screenshot from my video as the source?
Yes — screenshots, photos, and graphics from any design tool all work as source images here, as long as you have the file saved to upload.
Is this only for YouTube, or does it work for other platforms too?
The 1280x720 default is tuned for YouTube specifically, but the same pad-mode resizing works for any platform that expects a 16:9 thumbnail if you keep the same dimensions.
