Image Resizer

Drop an image below, set a new width or height (aspect ratio is kept automatically), and download the resized result. Your photo is processed locally and is never uploaded.

Width and height stay linked. No stretching.

Good to know

Each side must stay under 16,384 px. Large images are previewed at a smaller scale; the download is always full size.

Resizing changes dimensions; compressing changes file size. Image Compressor handles the other half.

How to use this tool

  1. Choose an image from your device.
  2. Set the width or height in pixels or percent; keep proportions to avoid stretching.
  3. Choose the output format, then select Resize & Download.

Example: resize by width

Input

1200 × 800 pixels; width 600 pixels; proportions kept

Output

600 × 400 pixels

Frequently asked questions

Is my image uploaded to a server?

No, resizing happens on your own device using your browser's canvas, so your image never leaves this page. Processing time depends on the image's dimensions and your device, so very large photos may take a moment to render and download.

Will resizing reduce quality?

Downscaling keeps images sharp (high-quality resampling is used). Upscaling beyond the original size will look soft, as no tool can add real detail.

Which formats are supported?

JPEG, PNG, WebP, GIF (first frame), BMP and SVG can be loaded. Output is PNG, JPEG or WebP, your choice.

Can I resize by percentage?

Yes, switch to % mode and enter e.g. 50 to halve both dimensions.
