Portable FastStone Photo Resizer 3.7 Free

A practical tool that you can use to change the resolution of photos and images while still maintaining their quality and colors


This is the portable version of FastStone Photo Resizer, a tool that lets you modify image files when it comes to their size, extension, name, and others.

Since installation is not necessary, you can simply place Portable FastStone Photo Resizer on an external device, so you can run it on any computer. Plus, your registry items remain intact.

Once you initialize the application, you will be greeted by a simple and intuitive interface in which you can use the Explorer-based layout or “drag and drop” function to add files into the input list.

So, you can select their output format (e.g. JPEG, BMP, GIF, PDF), set rename filters in the “Batch Rename” tab, as well as enable Portable FastStone Photo Resizer to keep their original date and time attributes.

If you access “Advanced Options” you will be able to configure settings when it comes to resizing, rotation, crop, canvas, color depth, effects (e.g. grayscale, negative, sepia, contrast, gamma) and DPI. But you can also add text, watermarks and borders.

Plus, you can save options to file and load them later, reset their values to default, enable Portable FastStone Photo Resizer to ask before overwriting files with the same name, change the interface skin, and more.

The application needs a low-to-moderate amount of system resources, includes a brief help file for newbies and quickly finishes a task without causing any problems. If we had to mention a negative aspect, it would be the interface’s appearance, since it looks a little outdated. Otherwise, we strongly recommend Portable FastStone Photo Resizer to all users.
