How to Resize Images Online
Use this free image resizer to change the dimensions of JPG, PNG, and WebP images directly in your browser. Select one or more images, choose your resizing method, and download the resized files when processing is complete.
Choose custom dimensions or a percentage
With custom dimensions, enter a target width or height in pixels. When Keep aspect ratio is enabled, the other dimension adjusts proportionally to help prevent stretching. You can also choose percentage resizing to scale an image relative to its original dimensions: 100% keeps the original dimensions, while a lower percentage makes the image smaller.
Will resizing affect image quality?
Resizing changes the number of pixels in an image. Reducing dimensions may remove detail, and enlarging an image cannot recreate detail that was not present in the original. For best results, choose dimensions that suit where you plan to use the image and keep a copy of the original file.
Supported formats and privacy
MARBPixel supports JPG, PNG, and WebP images. The resizer processes images in your browser, and you can download files individually or together as a ZIP archive. Your selected images are not uploaded to a MARBPixel server by this tool.
