Assetizr

Assetizr lets you crop, resize, and convert your images so you can optimize them for various purposes, including social networks, web tools, and mobile apps.

The cropping and resizing features are quite outstanding, giving you the ability to get perfect-sized new pictures out of desired image areas.

The tool allows you to import multiple files at once for batch processing. Loading files is done either by drag-and-drop or by browsing your computer from within the app. Adding an entire folder of files is also supported, as the utility is smart enough to select only images. Each loaded file support individual customization in terms of width, height, and output format. If your intention is to optimize images for uploading to social networks, you can use the available presets, specially configured for Facebook, Instagram, Twitter, LinkedIn, Pinterest, and Snapchat.

In addition, you can make custom and suggestively-named presets for later use.
Besides the wide range of presets, you will also appreciate the ability to save multiple crops out of the same picture. Each cropped area can be converted into the same format or saved with a different file extension.

To conclude, Assetizr is a reliable picture resizer, specialized in optimizing images for easy file upload. The utility supports the most common image formats, such as JPEG, PNG, TIFF, BMP, GIF, and WEBP, with the remark that it doesn't support converting each format into all the other formats - depending on the input, it will convert the image only into one or two related formats.
