Home / Free Image Resizer
Set image dimensions in pixels and download resized PNG images without sending them to a server.
Select an image, enter the maximum width and height, and process it. With aspect ratio enabled, the image is scaled to fit inside the requested dimensions without stretching. The resized image is exported as PNG. Larger images take more memory, so process very large batches in smaller groups.

If resizing is only one step in a larger editing job, GramFile has a guide to photo editing software for Windows with tools for broader image adjustments.
Pixel dimensions describe an image's width and height. To preserve its proportions, calculate the new width and height using the same scale factor rather than stretching one dimension independently. A resized image can be useful for profile photos, website thumbnails, forms and social media uploads.
Follow the exact pixel requirements published by the website or form you are uploading to. If no dimensions are specified, use a size appropriate to the display area and avoid enlarging a small image unnecessarily, because upscaling cannot restore missing detail.
