Client-Side Image Processing Security

Traditional image converter websites require users to upload sensitive graphics, thumbnails, and family photos to remote cloud servers for processing. CreatorKit Studio uses the HTML5 Canvas 2D API to render and scale pixels locally on your device's GPU/CPU, ensuring total data confidentiality.

Standard Social Media Image Dimensions

Always format images to platform-native dimensions: YouTube Thumbnails (1280x720, 16:9), Instagram Square (1080x1080, 1:1), Instagram Stories & TikTok Reels (1080x1920, 9:16), and Twitter/X In-Feed Images (1200x675, 16:9).

Frequently Asked Questions

Are my images uploaded to any cloud server?

No. All scaling, resizing, and compression occur 100% locally in your web browser memory. Your files never leave your machine.

What is the recommended size for YouTube video thumbnails?

YouTube officially recommends 1280x720 pixels with a 16:9 aspect ratio and a file size under 2MB.
