How does Photos Resizer works?

1. Add Images to Photos Resizer by simply dragging Photos Library, images or folders with images on the main Window.

2. The added Images are presented to be reviewed before proceeding to editing.

3. The next step is to Crop Images. If you do not want to apply Crop settings, you simply need to keep "Skip this Step" checked and proceed to next step using the "Next Button". "Skip this Step" is available on each step and should be unchecked to apply settings from that step.

4. You can select the Crop rectangle or use a pre-specified dimension to apply Crop setting. Once done, you just need to click the blue tick button to apply the selected settings on all the selected images.

5. If you are not happy with the crop settings, you can Reset the settings using the "Cross" button and the images will be reverted on the fly.

6. You can now move to the next step - Rotate where you can rotate the selected images. If you have applied the Crop settings, the images will first be cropped and then the Rotate settings will be applied.

7. After the rotate settings are applied (or the step is skipped), you can move to the next step where you can Resize the selected images.

8. After applying the resizing settings, you can proceed to next step of Renaming the selected images a per your preference to be processed and saved in new names.

9. In the Next step you can change the Output format of the images and can selected from various common formats.

10. If you have selected JPEG format in the previous step, you can optimize the images in the next step.

11. The next step allows you to select the Output folder where the processed images will be saved. You can even save the images to their source location.

12. Once you set the output folder, you can start the batch processing to process the images as per the settings selected on each step and saved to the specified output folder.

13 A summary of the settings applied will be presented after all the images are processed and saved.

Way too clunky

Takes forever to setup a process. Then once I do, it gives a nightmare of a path ot the processed images. I want to resize to a certain width and auto height, but the images are forced to be padded with a color. Definitely not for me. Need major improvements. I'll gladly change my review if improvements are made.

Dear Sir,

When you resize, on the resize settings screen, there is an option to give Background Color. Kindly keep that option unchecked and no background color will be added.
We will be more than happy to fix any and all issues you are seeing.
Kindly reach out to us on and we will take it up for you from there.
Many Thanks!
