Set exact width and height in pixels, lock aspect ratio to prevent distortion, or scale by percentage. Common presets for popular sizes make quick work one click.
Drop several images at once and resize them all to the same target dimensions. Each result shows the new size and file size, with individual or bulk download.
Resizing uses the HTML Canvas API right in your browser. There is no server, no queue and no size limit beyond your device's memory.
Your images never leave your browser. Nothing is uploaded, so it is safe for personal photos and confidential material, and it works offline once loaded.
No. All resizing runs locally in your browser using the HTML Canvas API. Your images never leave your device, nothing is uploaded, and the tool keeps working offline once the page has loaded. This makes it safe for personal photos and confidential material.
Yes. When the lock aspect ratio checkbox is on, changing width will automatically adjust height (and vice versa) so the image doesn't stretch. When it is off, you can freely set both dimensions to any value.
Yes. The percentage scale field lets you shrink or enlarge by a percentage of the original dimensions. For example, 50% will halve both width and height, and 200% will double them. This also respects the aspect ratio lock if enabled.
Shrinking dimensions will reduce file size because there are fewer pixels to store. For further compression or to keep the same dimensions but save space, use our Image Compressor tool.
Yes. Drop or select several images and they will all be resized to the same target dimensions. Each result shows the new size and a download link, or you can download them all at once.
This image resizer processes everything locally in your browser — your files are never uploaded to any server. Resizing changes pixel dimensions; use the Image Compressor to reduce file size without changing dimensions.
