Photos come in all shapes and sizes, but sometimes, you may need to resize them for best results.However, manually resizing a photo is easy and straightforward, but not so when you have thousands of photos to process.

How to Bulk Resize Photos by Mail Recipients in Windows 10

Most Microsoft Windows built-in photo editors, such as Paint and Photos, allow you to resize individual photos.Unfortunately, they don't yet support batch resizing of images.

Thankfully, you can easily batch resize photos in Windows 10 using a little-known mail recipient hack that tricks the system into thinking you want to email the photos.

4. Select the mail recipient from the fly-out menu.

5. Click the Image Size drop-down menu and select your preferred image size.There are only four options to choose from.

6. When finished, click Attachments.

7. The Microsoft Outlook Email Composer will start.Once it starts, click on the first picture.

How to configure PowerToys to display preset image sizes

If you regularly resize all your images to a specific size, you can configure PowerToys to display that image size by default without having to customize it each time you want to batch resize images.

In addition to image size, you can also configure encoding and file settings for the Image Resize tool in PowerToys. PowerToys also has a color picker that lets you find any color anywhere on the screen.

How to configure image size in PowerToys

1. Launch PowerToys from the desktop or Start menu, scroll down to the "General Settings" option, and click "Picture Resizer".

4. Click the pen icon to rename the new preset size and set the parameters.You can customize fit, width, height and pixels.

5. When done, just click anywhere outside the dimension editor.You can create unique preset sizes for different things, such as NFTs, Etsy, and Shopify.

6. To delete a profile, click the trash can icon to your right, then click Yes.

How to configure encoding options in PowerToys

By default, the image resizer will save the adjusted image in the source format, i.e. the same format as the original image.If this fails for any reason, Image Resizer will attempt to save the resized image in the format specified in Fallback encoding.

To configure encoding settings for Image Resizer, do the following:

1. While still in the Image Adjuster settings, scroll down to the Encoding section.

2. Click the Backtrack Encoding drop-down menu to your right and choose your preferred option.


3. By default, the JPEG quality level is set to 90%.You can adjust this with the slider.

4. Both PNG interlacing and TIFF compression are set as default.You can change these using the appropriate drop down buttons.

How to Profile Settings PowerToys Image Resizer

You can also specify how Image Resizer should name your resized images.The method is this.

1. Scroll down to the "Files" section of the Image Resizer settings.

2. Under File name format, click the space provided and specify how Image Resizer should name your resized image.For example, Etsy 1 (Etsy 2).This will help you differentiate between the original image and the adjusted image, as both are saved in the same folder.


3. Under File modified timestamp, you can click the drop-down list to select the preferred timestamp setting for the resized image.You can set it to be the time to resize or the time to create the original image.

Although these image resizer configurations are optional, they can help you improve and optimize your image resizing results.
