Keep aspect ratio
With “Keep aspect ratio” on, changing the width automatically updates the height so your image is never stretched.
Resize vs compress
Resizing changes the width and height in pixels; compressing reduces the file size in KB. A form that asks for “200 × 230 pixels” needs resizing, while one that asks for “under 50KB” needs compression. For both, resize first and then compress.
Pixels, inches and DPI
Printed size depends on DPI (dots per inch). At 300 DPI, a 600 × 600 pixel image prints at 2 × 2 inches — the standard US passport photo size. For screens, only the pixel dimensions matter.
Frequently asked questions
Can I resize to an exact size without stretching?
Turn off “Keep aspect ratio” to set any width and height. If the shape differs from the original, the image will be stretched, so crop first if you need to keep proportions.
Does resizing reduce quality?
Making an image smaller keeps it sharp. Enlarging beyond the original size can make it look soft, because new pixels have to be created.
Which output format will I get?
You can choose JPG, PNG or WebP.
Are my files uploaded to a server?
