Tips for Best Results

Privacy & Security

Your privacy is our priority. This image resizer processes all images directly in your web browser using HTML5 Canvas technology. No images are ever uploaded to our servers. This means:

Frequently Asked Questions

Is my image data secure when using this resizer?

Yes, absolutely. All image processing happens directly in your browser using JavaScript canvas technology. Your images are never uploaded to any server - they stay completely on your device. This ensures 100% privacy and security for your photos.

What image formats are supported?

The Image Resizer supports all common web image formats including JPEG/JPG, PNG, GIF, WebP, and BMP. The output is saved as PNG format to maintain quality, though you can also choose JPEG for smaller file sizes.

Can I resize multiple images at once?

Yes, you can upload and resize multiple images simultaneously. Simply drag and drop multiple files or select them using the file picker. All images will be resized to the same dimensions, and you can download them individually or as a ZIP archive.

What does 'Keep Aspect Ratio' mean?

The aspect ratio is the proportional relationship between an image's width and height. When 'Keep Aspect Ratio' is enabled, changing the width automatically adjusts the height proportionally (and vice versa), preventing your image from being stretched or distorted.
