About Image Resizer
Image Resizer lets you change the pixel dimensions of any image right in your browser. Upload a PNG, JPG, WebP, or GIF, type a new width and height, and keep proportions locked so the picture never looks stretched. It draws to a canvas and exports a clean PNG you can download instantly.
The tool is completely free with no sign-up, watermarks, or limits. Your image is processed entirely on your device using the browser canvas, so nothing is ever uploaded to a server. You always see the original versus new dimensions and file sizes before you download.
Frequently asked questions
- Is the Image Resizer free to use?
- Yes, it is completely free with no account, no watermark, and no usage limits. You can resize as many images as you want.
- Is my image uploaded to a server?
- No. All processing happens locally in your browser using the HTML canvas. Your image never leaves your device, which keeps it private and makes resizing instant.
- How do I keep my image from looking stretched?
- Leave the 'Lock aspect ratio' checkbox on (it is on by default). When you change the width, the height updates automatically to preserve the original proportions, so the image stays undistorted.
- What image formats can I upload?
- You can upload any format your browser supports, including PNG, JPG/JPEG, WebP, GIF, and BMP. The resized image is exported as a PNG.
- Does resizing reduce the file size?
- Often yes. Making the pixel dimensions smaller usually produces a smaller file. The tool shows the original and resized file sizes so you can compare before downloading.
- Can I make an image larger than the original?
- Yes, you can enter dimensions larger than the original. Keep in mind that enlarging beyond the source resolution can look soft, since the browser has to interpolate new pixels.
