About Image Resizer

Image Resizer lets you scale images to any size without uploading them to a server. Drag in a photo, enter the target width or height, and download the resized result instantly. All processing happens in your browser using the Canvas API.

You can lock the aspect ratio to avoid distorting the image, or unlock it to stretch to exact dimensions. The output is a clean JPEG or PNG depending on your input. This is useful for resizing profile photos, web assets, thumbnails, and attachments before emailing or uploading.

Very large images are supported as long as they fit in browser memory. For batch resizing hundreds of files, a dedicated desktop tool may be more practical.
