How to Resize Images for YouTube
Drop your thumbnail into ResizePack and choose the YouTube Thumbnail preset (1280×720 px, 16:9).
Thumbnails need strong contrast and readable text at small sizes — crop tightly around the subject using CropRatio at 16:9, then resize.
Keep the exported JPEG under 2 MB (YouTube's limit). Use the Compress tool to reduce file size if needed, then upload directly in YouTube Studio.

Use ResizePack for batch resizing with social media presets, or CropRatio to crop to the exact aspect ratio first.
Frequently Asked Questions
What is the ideal YouTube thumbnail size?
1280×720 px in 16:9 ratio is the ideal YouTube thumbnail size. It is displayed at multiple sizes — from tiny grid previews to full-width suggestions. Maximum file size is 2 MB. YouTube accepts JPG, PNG, GIF, and WebP.
What size is the YouTube channel banner?
Upload your channel banner at 2560×1440 px. The safe area visible on all devices is the central 1546×423 px zone. Keep your logo and key text within that area to avoid cropping on TV, desktop, and mobile.
Can I use a vertical image as a YouTube thumbnail?
No. YouTube thumbnails must be 16:9 (horizontal). If your source image is portrait, use CropRatio to crop it to 16:9 first, then resize to 1280×720 px.
How do I make a YouTube thumbnail stand out?
Use high contrast between the subject and background, a bold font for text overlays, and keep the most important element in the center-left third — that's where the eye naturally goes in thumbnail grids.
