Choose how to begin your thumbnail design
A thumbnail editor lets you modify an existing image - adding text overlays, adjusting colors, and layering elements on top of your photo. A thumbnail maker typically starts from templates or generates designs from scratch. Our tool combines both: start with a blank canvas or your own image, then add professional text, shapes, and effects. The result is a custom YouTube thumbnail built exactly the way you want it.

Our editor uses a 1280x720 workspace by default, which is practical for design and widely supported. Source: YouTube official guidelines. For the full breakdown, see our YouTube Thumbnail Size Guide.
This editor is built for speed: upload an image, add text and shapes, export, and move on. It works well when you already have a photo or screenshot and need to add a headline, an arrow, or a colored overlay before uploading to YouTube.
If you need pre-made templates, a stock photo library, brand kits, or AI-generated designs, tools like Canva or Adobe Express are better suited for that workflow. For advanced photo manipulation with layers, masks, and blending modes, desktop software like Photoshop remains the standard.

Yes. There is no payment, no signup, and no watermark on exported files. You can create and download as many thumbnails as you need. The editor runs entirely in your browser - your images are not uploaded to any server.
YouTube recommends 3840 x 2160 pixels for standard video thumbnails (16:9) and 2160 x 3840 for Shorts (9:16), with a minimum width of 640 pixels. Accepted formats are JPG and PNG. Our editor uses a 1280x720 workspace, which meets YouTube's minimum requirements and keeps file sizes practical. The exported file can be uploaded directly to YouTube Studio. For the full specifications, see our YouTube Thumbnail Size Guide.
Yes. The text tool supports six fonts (Anton, Bebas Neue, Montserrat, Bangers, Oswald, Roboto) with controls for size, color, bold, stroke outline, and drop shadow. You can add rectangles, circles, arrows, and lines. Each element can be moved, resized, rotated, and layered freely on the canvas.
Yes. You can upload JPG, PNG, or WebP images. Use "Upload Image" on the start screen to set a background, or click the Image button in the toolbar to add an image as a separate layer that you can move and resize independently. You can add multiple image layers on the same canvas.
This editor works on your local files, not on YouTube directly. To change a thumbnail that is already on YouTube: open this editor, create or edit the new version, export it, then go to YouTube Studio and replace the thumbnail on your video. YouTube does not allow editing thumbnails in place - you upload a new image file.
The editor loads on mobile browsers and supports basic touch interactions for moving and resizing elements. However, the editing experience is significantly better on a tablet or desktop where you have more screen space for the toolbar, canvas, and properties panel. If you primarily work on a phone, a dedicated mobile app like Canva may be more practical.
