Image Resizer

? Frequently Asked Questions

What image formats can I resize?

The resizer supports JPG, PNG, GIF, WebP, and AVIF formats. You can upload any of these formats and resize them while maintaining or changing the format during the process.

Will resizing reduce image quality?

Upscaling (increasing size) can reduce quality, making images pixelated. Downscaling (reducing size) maintains better quality. The tool uses high-quality algorithms to preserve sharpness, but always keep original files as backups.

Can I maintain aspect ratio?

Yes! You can lock aspect ratio to prevent distortion, or unlock it to stretch images to specific dimensions. Locked ratio automatically adjusts height when you change width (and vice versa).

What's the difference between pixels and percentage?

Pixels are absolute units (e.g., 1920×1080), while percentage scales relative to original size (50% makes it half-size). Pixels give exact control; percentages are convenient for proportional scaling.

Can I resize multiple images at once?

Yes! Batch resizing allows you to upload multiple images and apply the same dimensions to all of them. This is perfect for preparing images for websites, galleries, or social media.

Is my data safe and secure?

Yes, absolutely! This tool runs entirely in your browser. All data processing happens locally on your device - nothing is uploaded to our servers. Your files and data never leave your computer, ensuring complete privacy and security.
