About this tool

This free image resizer changes the dimensions of your pictures without any software installation. It is perfect for preparing photos for websites, social media profiles, email attachments, online forms with size limits, or printing. Because the resizing is done with high-quality canvas scaling, your resized photo stays as sharp as possible at its new dimensions.

Unlike many online resizers, this tool processes everything locally in your browser — your image is never uploaded to a server, so it works offline once loaded and your photos stay completely private. There are no watermarks, no sign-ups and no limits on how many images you can resize.

Frequently asked questions

Will resizing reduce my image quality?

Shrinking an image keeps it sharp because pixels are averaged together. Enlarging an image beyond its original size can make it look soft, since new pixels must be interpolated. For best results, resize down rather than up.

Is my image uploaded to your server?

No. The entire resize happens in your browser using the HTML5 canvas. Your image never leaves your device, which makes this tool safe for private photos and confidential documents.

How do I resize without stretching the image?

Keep the 🔗 aspect-ratio lock enabled. When you change the width, the height updates automatically (and vice versa), so the image is never distorted.

Which output format should I choose?

Use JPG for photos where small file size matters, PNG when you need transparency or lossless quality, and WebP for the best compression in modern browsers.
