Why You Resize Images?

Make a Passport Size Photo

As you may already know, passport images have specific size requirements. In most cases, authorities will take nothing less than 2 x 2 inches. In other words, your passport picture should be at least 600 x 600 pixels and not exceed 1200 x 1200 pixels. In addition, you can also change the photo size to fit the brand-new frame you've just bought on Amazon.

Resize a YouTube Thumbnail

A YouTube thumbnail is a must to attract the viewer's attention on YouTube and tease them to open the video. However, you can't just upload any photo. A YouTube thumbnail should measure 1280 x 720 pixels with a minimum width of 640 pixels. For this reason, use Image Resizer to change photo size quickly and easily.

Resize Facebook Profile Photo

With Facebook becoming more and more of an online biography like Linkedln, it's paramount to make sure that the profile photo you add meets the requirements. Using a profile picture that's too small can crop out important parts of the image. Therefore, it's recommended to use the highest possible resolution of 2048 x 2048 pixels. The minimum recommended size is 761 x 761 pixels.

Resize Photo for Instagram

Knowing the required Instagram image size can also help you rake in more views and followers. That's because Instagram compresses your photos when you upload them. For horizontal posts, your image size should be at least 1080 x 1080 pixels, whereas vertical posts should measure 1080 x 1350 pixels. In addition, the photo can be square, vertical, or horizontal.
