You can resize JPG, PNG, and WebP images, and download the result in the same format you uploaded.
Yes, resizing images is completely free, with no signup and no watermark added to your files.
Resizing changes an image's width and height, not directly its file size in KB. If a form asks for both a specific pixel size and a maximum file size (common for job or exam applications), resize to the required dimensions here first, then run the result through our image compressor to bring it under the KB limit.
No, the resized image keeps its original format (JPG stays JPG, PNG stays PNG) unless you choose to convert it separately.
Resizing changes the image's width and height (its dimensions). Compressing reduces the file size in KB or MB while keeping the same dimensions. If you need both, resize first, then compress.
