Frequently asked
What's the best size for social media previews?+
1200×630 pixels is the standard Facebook size and works well on LinkedIn and most other platforms. Twitter/X accepts up to 1200×675.
Cover vs. Contain?+
'Cover' fills the whole canvas by cropping edges. 'Contain' fits the entire image with letterboxing (useful when you can't afford any cropping).
Is my image uploaded anywhere?+
No — resizing happens entirely on your device using the HTML canvas API. Nothing leaves your browser.
What formats are supported?+
Any image your browser can decode — PNG, JPEG, WebP, GIF, BMP. Output is always PNG for maximum compatibility.
