WebPconv

WebPconv is a straightforward application that targets users in need of a quick tool for converting large image collections to WebP format. This can greatly minimize the impact of your digital albums on the HDD space, due to the high compression ratio involved in the process.

WebP is a relatively new image format that relies on lossy and lossless compression algorithms in order to optimize digital photos. The compression level can go up to 30% without significant loss in quality, which is a tremendous gain in terms of space and even sharing, since many email or hosting services are conditioned by size restrictions.

WebPconv adopts an elegant interface that hosts two tabs: one belonging to the compression engine, which converts image files to WebP format and one for reverting the process – that is, decompressing the WebP images to their original form.

With WebPconv, you will be able to compress and decompress multiple files at a time. Images can be added by drag and drop exclusively and are listed together with details such as type, original size, new size and status (the last two fields are filled in after the conversion is finished, reflecting the gain achieved through the process).

By default, the program is set to a compression factor of 75, which is a pretty high value that might result in quality loss. However, you may choose a custom factor using the Options menu.

Also from this section, you will be able to turn the lossless mode on or to set the application to seek for a well-balanced quality level through the Auto Filter option.

WebPconv is a great asset if you need a fast image compressor. Conversion speeds are variable, depending on the size of the originals and on the number of files in the queue.
