How to use the image Resizer
- Click the upload area (or drag and drop) to select an image.
- Enter your target width and/or height in pixels.
- Leave 'Lock aspect ratio' checked to avoid stretching, or uncheck it for exact custom dimensions.
- Click 'Resize image', then download the result.
Example
Uploading a 3000×2000 px photo and setting the width to 1200 px, with aspect ratio locked, automatically resizes the height to 800 px — keeping the image proportions unchanged.
Why resize images online?
Websites, forms and marketplaces often require images at specific pixel dimensions. Resizing in a full photo editor is overkill for a quick task like this — this tool resizes a single image in seconds, directly from your browser.
No upload, no quality surprises
Resizing uses the Canvas API locally on your device, so your photo is never sent to a server. You can compare the original and resized versions side-by-side before downloading.
Frequently asked questions

No artificial limit is enforced, but very large images may take longer to process depending on your device's memory.
