ImageFrequently asked questions
Is the aspect ratio preserved when resizing?
If you keep the lock option enabled, the tool uses the width as the reference and computes the height proportionally. Turn it off if you want to force the exact dimensions you typed in.
Can I scale an image up?
Technically yes, but keep in mind that enlarging an image loses sharpness. The tool does not invent detail, so it's always better to start from a source image that is large enough.
What format does the resized image use?
By default the same format as the source image. If you pick a specific format (JPG, PNG or WEBP), the image is resized and exported directly in that format.
Does it work with several images at once?
Yes. Drop several at once and each is resized with the same dimensions and format. Results download one by one.
