Image Resizer

About Image Resizer

Resize images to specific pixel dimensions or by percentage. Maintain aspect ratio or set custom width and height. Processed entirely in your browser.

How To Use

  1. Drop in a JPG, PNG, or WebP — or click to choose one from your device.
  2. Enter a target width or height, or a percentage. Keep "lock aspect ratio" on to scale proportionally, or turn it off to set exact dimensions.
  3. Download the resized image. The original is never uploaded — resizing happens on a canvas in your browser.

Example

Input: A 4000×3000 phone photo that needs to be 1200px wide for a blog post.

Output: A 1200×900 image scaled proportionally, downloaded in seconds with no quality sent to a server.

Who Uses Image Resizer

  • Designers and creators who want private image tools (crop, compress, convert).
  • Anyone processing local photos without ever uploading them.
  • People who want private — files and text stay on your device and are never uploaded to a server for images.

Frequently Asked Questions

Will resizing reduce quality?

Downscaling keeps images sharp; enlarging beyond the original size can soften detail, since there is no extra information to add. For best results, resize down from a larger source.

Are my images uploaded?

No. The image is drawn to a canvas and resized entirely in your browser — nothing is sent to a server.
