Today’s mobile devices take incredibly beautiful photos, but all that detail comes at a price — size. Therefore, you need a good image resizer app that will re-size your photos instantly without losing any quality.

The Problem: Great Pictures Sized Too Large

Let’s face it; our entire lives are now cataloged digitally due to mobile devices everywhere. That means a lot of photos, and because of the high level of quality, these photos have gotten huge! Most pictures taken on a typical phone camera are at least 2000 pixels wide and some clock in much larger.

The problem is that many of us post regularly to social media, and these photos are too big to fit the platform’s requirements. Therefore, every photo you take, before uploading it to Facebook, Instagram, or other social media sites, has to be cut down and sized accordingly.

The Solution: Free Photo Resizer Apps

The good news is, there are dozens of photo resizer apps out there to make that job quick and easy. Most of them are free but may include some in-app purchases such as additional filters or features to enhance your photo editing capabilities. If all you want to use it for is to resize your pictures for social media, most free offerings will suffice.

What Features Make a Good Picture Resizer App?

When evaluating what makes a good image resizer app, good, we had to look at a few different things. Most image resizers will, of course, allow you to resize your image. However, if you know anything about the way image sizing works, you know that it’s not always that easy.

Sometimes a photo doesn’t fit well into the new chosen size. In that case, you need to crop or fill that size canvas with a portion of your photo. These types of things are essential and shouldn’t be overlooked when picking an image resizer. Other features we like to see in a good, free photo resizer are:

  • A rotate feature.
  • Easy-to-use interface.
  • Adjustments for color, light, and balance.
  • Filters for fun to enhance already great photos.
  • Blemish correction or retouching for red-eye.
  • Special effects.
  • Presets for size or combo effects.
  • Available on both Apple and Android devices.

1. Resizing.app

One of our favorites is an online image resizer, called Resizing.app. The company has a straightforward website and process to resize images online within seconds. One of the coolest features is the ability to export your newly sized image into a different format.

Resizing.app couldn’t be easier to use. You simply drag and drop your images into the box on the home page. Then you select how you want to resize your image (width only, height only or custom). You can choose to optimize your image for quality assurance and then just pick your new file format (jpg or png). Once you hit the save button, your new image is saved to your computer. Voila’ all done. No frills but also no hassles.

Unfortunately, this online service does not have any additional photo editing capabilities to go along with resizing. But hey! It’s free, and we like free and simple.

If you resize your images and photos regularly, we highly recommend you to add the Resizing extension to your Google Chrome; it is also entirely free.


2. Instasize Photo Editor

Used by almost 150,00 people, this app is very easy to use. It opens to a white screen with a black plus button. Just tap the plus to select a photo from your device and then start editing. The built-in filters are stunning. We also love their preset crop sizes for Instagram, Facebook, Pinterest, and Twitter. It’s a breeze to navigate and change settings for exposure, contrast, Lux, brightness, sharpness, and dozens of other settings. You can also add text (using different fonts) and a colored border.

What we don’t like about Instasize is the free version is good for only seven days, and then you must buy the full version to continue using it. What this app lacks in retouching and effects, it makes up for in easy resizing for photos to post on social media.


3. Image Size Photo Resizer

This photo resizer app is fantastic in so many ways. First, the interface is super easy to use. You don’t have to guess where to go to start editing. One of the most delightful features is that you can enter in an exact size in pixels, mm, cm or inches, and your photo is instantly resized. This one also includes tools like color overlay, filters to enhance your photo, adjustments for color and brightness, fun effects, blur, and focus, flip, and you can even draw on your images to add more panache.

The downside to Image Size is that the free version includes ads and you have to watch a 30-second ad before saving your edited image. However, this app is so good; we think it’s worth purchasing the pro version.

4. ReSIZER - Simple Photo Resizer

If you want the simplest, free picture resizer on the market, then this one is for you! The plain interface offers a big plus button on a white screen to begin. Once you select your image, you have only three options: rotate, crop, and resize. That’s it! Using this app is so quick and easy. It does the job without any fancy add-ons, but it does allow you to share your resized image with others.

Other than having very few options to choose from, the only other downsize to Resizer is that it only works on Apple phones. Sorry, no Android version is available yet.


5. Photoshop Express: Photo Editor

Clearly, a lot of people like and use this app. Although Adobe is not often known for ease-of-use with their applications, we found this photo editor to be very easy to use. Adobe makes it a snap to quickly resize your images using templates for many popular social media platforms like YouTube, Facebook Cover photo, ETSY cover photo, Pinterest, and more. This app also supplies a bunch of custom sizes and device options for sizing. However, the one negative is you can’t specify your own size in pixels or inches. For us control-freaks this is a big deal.

Photoshop_Express

That being said, Photoshop Express: Photo Editor is truly a full-featured, free photo editor. Not only do they pack in some great special effects to turn ordinary photos into masterpieces in seconds, but they also check all our boxes with rotation, color and brightness controls, photo retouching, the ability to add text and much more!

This is a great application but might be more than you need if all you want to do is resize your photos. Keep in mind though, it is completely free so if you don’t mind preset sizes, this one is a gem.

User ratings: 4.8 stars from 480k Apple users.


Conclusion

Although we reviewed a few solid options for image resizing, it’s really a matter of personal taste. If you want no-frills and no hassle, Resizer is your tool. If you are on the computer and don’t have access to your images on a mobile device then Resizing.app is definitely the way to go. However, our favorite pick for the mobile device apps would have to be Adobe’s Photoshop Express. The combination of features and powerful effects was intoxicating and it’s free to boot!

However, Image Size came in at a close second, and we love the ability to micro-manage the image size using a number for height and width.
