How to use it

  1. Drag your image onto the box above, or click it to pick a file from your device.
  2. Enter the width or height you need. Leave “Lock aspect ratio” on to avoid distorting the image.
  3. Choose an output format and quality level if you want to change them.
  4. Click “Resize” and download the result.

Sometimes you need an image at an exact size: a profile photo for a government portal, a product cover for an online store, or an attachment that rejects anything above a certain width. This tool lets you set dimensions in pixels or by percentage, with an option to lock the aspect ratio so the result never looks stretched.

The key difference between this tool and most similar sites is that your image is never uploaded to a server. Your browser reads the file locally, redraws it at the new dimensions, and hands you a download. That means sensitive material — ID photos, contracts, anything private — stays on your machine and nowhere else.

JPG, PNG, WebP, GIF and BMP are all supported, and you can pick an output format and quality level independently of the source format. If your goal is a smaller file size in megabytes rather than smaller dimensions, the image compressor is the better fit.

Frequently asked questions

No. The tool runs entirely inside your browser using the Canvas API, and no part of your image is sent over the internet. You can verify this by disconnecting from the internet after the page loads — the tool keeps working.

We impose no limit, but processing uses your device's memory. Images up to around 50 MB are usually fine on modern hardware; much larger files may be slow on older phones.

Shrinking an image inherently discards detail, but results stay sharp because the browser uses high-quality resampling. Enlarging a small image cannot invent detail that was never there, so the result may look soft.

Yes — select multiple files and the same settings are applied to all of them, then downloaded together.
