About Image Resizer
For designers, content creators and office workers, the Image Resizer turns minutes of manual working into an instant, clearly labelled result. Resize an image to exact dimensions or a percentage in the browser, with the tool keeping the aspect ratio optionally and offering a crop mode for a fixed shape. Indian users constantly meet size requirements - a passport photo at 35 by 45 mm, a form upload at 200 by 200 pixels, a WhatsApp share at a smaller width - and the tool hits these precisely. The tool also shows the new file size, which matters for size limits, and handles batch resize of several images. Because the file is processed locally, personal photos never leave the device. It is the resizer that a portal rejection for wrong dimensions always needs. Your photos stay on your device because every conversion and resize happens locally in the browser - no uploads, no server copies, no waiting in a queue. It earns its keep when resizing a photo for a form upload, when making a passport-size photo, and whenever batch resizing images for a site. Everything is free with no usage caps, and nothing asks for your email address.

Frequently Asked Questions
