Resize your photos in batches with Fotosizer

Once we run Fotosizer we check that it contains a clean and intuitive design where we can import photos using its navigation button or drag and drop support. In addition, it is possible to add the content of a complete folder and delete all the elements that we have selected.

The program allows us to create a list of elements that we want to process in batches and switch between different view modes (Preview Panel, Details and Thumbnails, as well as choose the columns that are revealed in the main window such as size, creation date, camera, ISO speed, copyright, aperture, copyright, among others.

Once we have added the photographs, on the right side we find a column with the different options that we can carry out on them.

Configure resizing

From this section we will be able to make the necessary adjustments for resizing these images. Here we find the possibility to Fit, Stretch, Border, Fill with and Crop. We will also be able to select the custom size for Width and Height, either in pixels, percentages, centimeters, millimeters or inches.

Fotosizer performance settings

We also have the Preset size option, with different default size settings such as the screen size of different devices such as PSP, iPhone, iPod or different Android mobiles. Of course, it must be said that the models that appear are quite old and most of them are already in disuse or obsolete, so they will not be very useful either.


The next section will give us the possibility of giving our photos different effects. In total they are 15 effects available in the free version such as Black and White, Negative, Sepia, Spine, Pixelate, Vignette, Monochrome, Polaroid, Old Photo, Soft Color, Vibrant Color, Gotham, Cool, Warm and Dark. Perhaps in this section we miss the possibility of seeing a preview of how the final result looks.

Rotation, Miscellaneous and Destination Settings

Next, we go to the “Rotation” section, from where we can make adjustments to rotate images 90 degrees counterclockwise, 90 degrees clockwise, and 180 degrees. We can also rotate the photos horizontally or vertically.

Right after we find the “Various” section, from where we will be able to modify the image quality, change the print resolution and apply image optimization. We can also copy the EXIF ​​(JPEG) information from the metadata of the images, as well as keep the creation date of the original file and save the modified file the original date.
