Great for doing basics like crop, rotate, contrast, etc.

I use Sly for quick and dirty image manipulation. It has enough features to do basic stuff like brightness, contrast, saturation, noise reduction, sharpness, rotation and so on. But I miss a feature to change the size of the picture or the canvas.

Sly is interesting, because it tries to do a photo editing app, but it just doesn't understand any basic photo editing principal, so the final result is sub-par with any other photo editor. I am a professional photo editor, and I use darktable for precise color adjustments, and this app is just worst than lightroom in that regard. BUT if you want something simple and basic, it is a great option, just be aware, that it is really limited and the available tools are based on old and outdated photo editing practices...

What is Sly?

Sly is a friendly image editor that requires no internet connection or preexisting expertise. Just open a photo and have at it.

The app allows you to adjust simple attributes like brightness or contrast as well as effects like a vignette or a border. It also allows you to flip, rotate and crop the image to your heart's desire.

When you're done, just export the photo as a JPEG or a PNG with the quality settings of your choosing. You also get a choice in whether or not to keep metadata such as location information.
