Choose a YouTube preset, preview the framing and export the exact dimensions without uploading your image. Use the available YouTube destinations for posts, profile images, covers or channel artwork instead of entering dimensions manually. The source file remains unchanged and all processing runs locally in your browser.
Why use this tool
- Choose among 3 YouTube presets read directly from the tool configuration.
- Use Fit to keep the complete image or Fill for a centered crop to the selected ratio.
- Preview and process the file locally without sending it to an image server.
How it works
- Choose a JPG, PNG or WebP image and check the preview.
- Select the required YouTube purpose and choose Fit or Fill.
- Resize and download the image at the selected YouTube dimensions.
YouTube sizes available in the tool
Thumbnail (1280 × 720 px), Channel banner (2560 × 1440 px), Profile picture (800 × 800 px)
YouTube crops channel banners differently across devices.
YouTube displays profile pictures as circles.
Fit, Fill, quality and transparency
Fit preserves the complete image. When padding is needed, it is transparent for PNG and WebP and white for JPG.
Fill covers the entire target ratio with a centered crop, so source pixels near the edges can be removed.
The result keeps the input format. JPG and WebP use the configured export quality; PNG retains an alpha channel when present.

Frequently asked questions
Are my images uploaded?
No. Processing happens locally in your browser, so your image files never leave your device.
Does Fit crop my image?
No. Fit keeps the complete image and adds empty space when its aspect ratio differs from the preset.
Which YouTube sizes are available?
Thumbnail (1280 × 720 px), Channel banner (2560 × 1440 px), Profile picture (800 × 800 px)
What is the difference between Fit and Fill?
Fit keeps the complete image and may add space. Fill covers the target ratio with a centered crop and may remove edges.
What happens to transparent padding?
Fit uses transparent padding for PNG and WebP. JPG cannot store transparency, so its padding is white.
Does the result keep the original format?
Yes. JPG stays JPG, PNG stays PNG and WebP stays WebP.
Can I resize for social media on a phone?
Yes. The controls and preview work in a current mobile browser.
