TinyPNG is easily the coolest tool I’ve come across recently. I was looking for an easy way to compress images used on LunchBunch’s website to improve load times, and TinyPNG couldn’t have made it any easier. I’ve compressed PNGs and JPGs (it works with both) with average compression results between 40% and 80% depending on the source and original size. The website is very easy to use too–just upload your images and download a zipped file containing the compressed versions (or optionally save directly to Dropbox). And it works just as well on PNGs with transparency.
Compression is awesome, but what about the quality? PNGs are lossless, meaning that an image won’t change when compressed, but the quality of JPGs deteriorates as the file size shrinks. You don’t have to worry about image quality with TinyJPG–see for yourself at the bottom of TinyJPG’s homepage. The compressed version is barely a quarter of the size of the original, but I can’t tell the difference between the two images!
So after learning all of this, I was hooked. I was excited to use TinyPNG for everything, but what if I want to tinify my images programmatically? Lo and behold, the developer API! With libraries for Ruby, PHP, Node.js, Python, and Java, it is very easy to incorporate TinyPNG into any project. For example, my first attempt in Python was just a few lines:
import tinify tinify.key = "<your-developer-api-key>" def tiny(input_filepath, output_filepath): source = tinify.from_file(input_filepath) source.to_file(output_filepath)
And it just worked!
It seems easy to preserve metadata, integrate with Amazon S3, and even crop/resize before compressing (though I haven’t explored these features yet).
Every once in a while you stumble across a tool that’s exactly what you were looking for. For me, TinyPNG was that and more. If you have a website or use pictures in any way, this is a must-have tool for your project. There’s also a WordPress plugin that is super simple and highly-recommended for your blog.
