Image resizing
Resizing App offers a high degree of freedom in image resizing and is easy to use. It provides custom width, custom height, custom length, percentage, and various options for all customization:

The Resizing App Chrome browser extension supports importing images in PNG, JPEG, BMP, TIFF, HEIC, GIF and WEBP formats. As for the transferred images, you can choose JPG, PNG, WEBP, BMP and TIFF formats:
