MADE SIMPLE
Change JPEG dimensions in a few clicks
JPG is widely used for photographs because it balances detail with compact files. To resize a JPG, enter exact pixel dimensions or choose a percentage. The aspect ratio lock helps avoid distorted faces and stretched objects.
For a quick JPEG dimension change, drag the blue handle on the image or the horizontal size slider to reduce or increase the photo dimensions while preserving proportions. For a custom shape, select Crop or Pad. When exporting a JPEG, you can lower the quality setting to reduce its file size. JPEG does not support transparency; any transparent areas are filled with your selected background color.

GOOD TO KNOW
Frequently asked questions
How do I change the pixel dimensions of a JPG?
Choose the image, enter the new width and height in the pixel fields, then click Download resized image to save the actual resized file.
Can I make a JPG bigger?
Yes. You can increase the width and height, but enlarging cannot restore detail that was not present in the source.
How do I change the aspect ratio of a JPG without stretching?
Select Crop to fill to remove edges, or Pad to exact size to add a border. For a proportional resize, drag the horizontal size slider with the ratio preserved.
Can I upsize JPG images online?
Yes. Drag the resize control to the right or enter a larger pixel width. The resulting JPG has more pixels, but does not gain missing original detail.
Is JPG the same as JPEG?
Yes. JPG and JPEG refer to the same image format; they are different filename extensions for the same encoding.
