Set width and height or choose a preset, then download your resized image.
Browser processing · No account · FreeHow it works
Choose an image, enter width and height, or pick a preset. Keep aspect ratio fits the whole image inside both limits without cropping, so one output dimension may be smaller. Turn it off only for exact dimensions with stretching.
Things to know
Up to 15 MB and 30 MP input. Output dimensions: 1–6,000 pixels each, up to 20 MP total. PNG output preserves transparency. Enlarging an image does not create new detail.

Need a horizontal post? Choose a 1,200 × 630 bounding box with aspect ratio preserved to keep the whole image.
