Frequently Asked Questions

Is my image uploaded to a server?

No. All image processing happens entirely in your browser using the HTML5 Canvas API. Your images never leave your device, ensuring complete privacy and fast processing.

Can I maintain the aspect ratio while resizing?

Yes. Toggle the aspect ratio lock to automatically adjust the height when you change the width (or vice versa), preventing any image distortion.

What image formats are supported?

The tool supports all common web image formats including JPEG, PNG, WebP, and GIF. You can resize any image your browser can display.

What dimensions should I use for social media?

Common social media image sizes include: Instagram post 1080x1080 (square) or 1080x1350 (portrait), Facebook post 1200x630, Twitter/X post 1600x900, LinkedIn post 1200x627, and YouTube thumbnail 1280x720. The tool includes presets for these popular platforms.

Does resizing reduce image quality?

Scaling down generally preserves quality well since you are reducing pixels. Scaling up (enlarging) can cause blurriness because the tool must interpolate new pixels. For best results, always start with the highest resolution original and scale down to your target size.
