When using the online image compressor, my files download as TXT files

If you use our online image compressor, there is a possibility that you will encounter a strange problem: Your files are downloaded as TXT files or files without extension.

This is a rare problem that occurs on certain operating systems when image filenames contain spaces and/or special characters like '#'. To solve the problem, simply  rename your image file before uploading so that it does not contain spaces or special characters.

For example, rename featured image #CF7399.png to featured_image_CF7399.png.
