There are many different ways and many different apps that allow you to censor a racy photo and then share it to Instagram or Facebook. If you're in a time crunch and don't have the time or the patience to deal with something like Photoshop, then Snapseed is a great and easy app that will blur out your raunchy images in a quickie.
Snapseed is an app that you should definitely be using not only if you're really serious about photography, but also if you want to ensure that your online work sets the standard for social media. It's a great companion app to Instagram and VSCO, and it will save your day many times over when you find yourself on your phone, on-the-go, needing to edit an image beyond the typical everyday filters.
If you've ever wondered how to import your photos in Snapseed, then you've come to the right place. Snapseed is a wonderful photo-editing app and will provide you with many tools to take your photos to the next level. But you can't get to that next level if you don't know how to get your images into Snapseed in the first place.
