Resize image
Choose a picture and set a new width and height in pixels, or scale it to a percentage of its original size. With the aspect ratio kept, typing one side fills in the other.
The image is resized in your browser and downloaded to this device. Numelivo does not receive it.
Your image stays on this device. It is processed in your browser and never uploaded. There is no account and no daily limit.
How to use this tool
- Choose an image, or drop it on the box. It is not uploaded.
- Pick pixels or a percentage. For pixels, type the width or the height; leave “Keep the aspect ratio” on so the picture is not stretched.
- Press Resize image, check the preview and the new file size, then download the result.
Questions
Is my photo uploaded when I resize it?
No. The resizing happens in your browser with the canvas feature, and the file never leaves this device. There is no account, no watermark, and no daily limit.
Which format is the resized image saved in?
PNG, JPEG, and WebP pictures keep their format. Other formats, such as GIF or BMP, are saved as PNG so no quality is lost. A resized animated GIF keeps only its first frame.
What is the largest size I can make?
The longest side can be up to 16,384 px and the whole picture up to about 67 megapixels. Beyond that most browsers cannot create the image, so the tool stops with a message instead of freezing.
