Frequently Asked Questions

What image formats are supported?

The image resizer supports JPG, PNG, WebP, GIF, and most common image formats. Simply upload or drag and drop your image to get started.

What are the best Instagram image sizes?

For Instagram: Post (1080×1080), Story/Reel (1080×1920), Landscape Post (1080×566). All these presets are available in the Social Media tab for instant resizing.

Is my image uploaded to your servers?

No! This tool works entirely in your browser using the Canvas API. Your images never leave your device, ensuring complete privacy and security.

Does resizing reduce image quality?

When downsizing, quality loss is minimal using our high-quality smoothing algorithm. When upsizing beyond original dimensions, some quality loss may occur. We recommend keeping images at or below their original size.

Can I maintain the aspect ratio?

Yes! In the Custom Size tab, enable 'Lock Aspect Ratio' and changing one dimension will automatically adjust the other to maintain your image's proportions.

What's the difference between aspect ratios and social presets?

Aspect ratios (16:9, 9:16, 1:1) maintain proportions at high quality. Social presets provide exact pixel dimensions required by each platform (Instagram, Twitter, etc.).
