How to resize an image
Choose, drop or paste an image, then enter the width or height in pixels, or use a quick size: 75%, 50%, 25% or the original size. Press Resize image. The result shows the size measured from the real file, and the file name includes the new size, such as photo-800x600.jpg.
Keeping the aspect ratio
With the aspect ratio locked, changing the width updates the height (and the other way round), so the image is never stretched. If you unlock it and set a ratio that differs from the original, you're warned that the image will be stretched or squashed.
Making images larger
You can set a size larger than the original, but enlarging doesn't add detail: the image may look softer and the file may get bigger. You're told when a size enlarges the image.
File size, format and quality
Keep the original format, or save as JPEG or WebP; the quality setting applies to JPEG and WebP. Making an image smaller in pixels doesn't always make the file smaller, especially for PNG. To shrink the file without changing its dimensions, use the Image Compressor.
Privacy, orientation and limits
Images are resized in your browser and never uploaded. Sizes follow the orientation you see (already rotated by camera data). The new file has no metadata such as GPS location. The new size can be at most 16,384 pixels per side and 40 megapixels.
Frequently asked questions
What size should I use for a website or profile?
Use the size the platform asks for. If you don't know, 1,200–2,000 pixels on the long side usually suits a web page.
Will portrait phone photos be rotated wrongly?
No. The orientation you see is the one that is saved.
