"Batch Image resizing made easy"


Resizing images is not very uncommon, therefore a lot of tools exist on the web that do this exact job. Fotosizer is one of them and gives you the power to tweak many settings before performing batch conversion operations, such as resizing by percentage, set custom height and width, keep aspect ratio, rename output files using custom rules, add effects and view thumbnails.


It’s only a matter of seconds to finish the installation procedure as there are not many or difficult steps throughout it. No additional software will be installed alongside Fotosizer, and the setup package is clean from any types of malware (view report).

Supported operating systems are Windows 98, ME, 2000, XP, Vista, 7 and 8. No special requirements are needed.


In substance, the main window of Fotosizer is split into two vertical parts. The left part is where you add the photos you want to convert, with a small thumbnail next to each one. The right part has all the available settings split into sliding categories that you can hide and unhide by clicking on the arrow located on the top right corner of each one. At the bottom of the window are a few buttons for importing files and folders, as well as for starting the conversion process and exiting the program.

At the top is the logo of the program along with some useful links (online help, check for updates and donate) and a button which opens the options window.


No matter how many images you add, Fotosizer will resize them without questions and crashes. You can resize images by percentage or by setting custom values for width and height. If you’re not sure which dimensions would be good for your images you can select one of the preset sizes. If you’d like to maintain aspect ratio just enable the corresponding checkbox located with the rest of the settings.

Some extra features include adding effects (black and white, negative and sepia), rotating the images by 90 degrees clockwise/counterclockwise or flipping them horizontally/vertically, changing quality and printing DPI to a specified percentage as well as copying EXIF and XMP information (for JPEG images only).

But Fotosizer is not just a resizing tool; it can also convert images between the following supported file formats: BMP, JPEG, PNG, GIF and TIFF.

Output files can have a filename defined by the available masks, so for example their name can be their dimensions in pixels, their percentage width/height or the conversion date.


Well, as long as the additional features don’t confuse inexperienced users who just want to resize their photos, everything is good.


Phatch is a freeware application for Windows, Linux and Mac operating systems with the main purpose of processing tons of image files easily. It can resize, rename and perform other operations on images you give it without having to configure it much. Other substitutes are FastStone Photo Resizer (paid), Image Tuner (free) and Fast Image Resizer (free).


There is nothing that will make this program stand out from the rest, as it does pretty much most of the things other tools do. Nevertheless, it fulfills its reason of existence wonderfully.
