Use the "Local file" or "Online file" buttons to specify how to upload the image to the server. Use the "local file" if you need to convert a file from your computer, in order to specify a file on the Internet, select "Online file" and in the appeared field paste the link to the file. We do not set any limits on the size of the image file, but the larger the file, the more time it will take to convert. Just be patient and everything will turn out.
If you need to change its size, then just specify the size in the "Change the size" field the width and height of the image. If you need exact adjustment in height or width, then just specify it and set the flag "Save proportions", in this case the converter will convert the file according to your condition, the second one will be calculated automatically.

Compare XWD with WEBP
Format introduction
In the X Window System, the program xwd (X Window dump) captures the content of a screen or of a window and optionally saves it into a file.
WebP is an image format employing both lossy and lossless compression. As a derivative of the VP8 video format, it is a sister project to the WebM multimedia container format. WebP-related software is released under a BSD license.
Technical details
xwd runs in one of two ways: if a user specifies the whole screen or the name or identifier of a window as an argument, the program captures the content of the window; otherwise, it changes the shape of the cursor and waits for the user to click in a window, whose content is then captured.
Google has proposed using WebP for animated images as an alternative to the popular GIF format, citing the advantages of 24-bit color with transparency, combining frames with lossy and lossless compression in the same animation, and as well as support for seeking to specific frames.
