Smartphone cameras are professional digital cameras for your pocket. You can make the best of photos with it. There are many reasons why you should edit your photos before you publish them. Whether you're an amateur or a professional photographer, you will find a photo editor app extremely useful for photo retouching, color correction, old photo restoration, resizing etc. 

How to choose the best photo editing app for you 

It’s a question of balancing your needs with the complexity of the interface and how much in-depth editing you want to do. There are some superb apps that will give you better-looking photos with just a few taps, but if you want to go beyond that and control every aspect of your photo’s tone and intensity, you’ll need something with more tools and features.

I've chosen the top 3 best free photo editor that you can use without paying a hefty price.

1. Snapseed
Snapseed is one of the best free online photo editor app developed by Google. The app has 29 tools and filters to enhance your photos, including Healing, Brush, Structure, HDR, Tune image, Perspective, Details, and lot more. You can also share your creations with its export tool.

2. Adobe Photoshop Express
Photoshop Express Collages gives you flexibility and control of images ranging from border size, color, individual pan, and zoom. If you just want to quickly give some punch to your picture, Photoshop Express is the app for you. It offers a selection of “Looks”, which are single-tap filters with a simple strength control to adjust the intensity of the effect. While some Looks are a bit outlandish, most have subtle, flattering effects, which don’t make your picture look too obviously processed.
You will be able to remove red-eye, resize images, make color corrections, and more.

3. Adobe Photoshop Lightroom
Adobe Photoshop Lightroom CC is my favorite desktop application for serious photography. It's a free, powerful, yet intuitive solution for editing, sharing and capturing your best photos. The mobile version – available for iPhone, iPad and Android devices – serves as a companion app, allowing photographers to access and edit their photo libraries via the cloud.

The great benefit of Lightroom is that you can edit large quantities of image files simultaneously without destroying the quality of individual photos. Though designed for professional photographers, it is very easy for amateur and semi-professional photographers to learn Lightroom, and they can get benefits from using this program.
