The free tool Jpeg.io lets anyone convert their existing images into optimized JPEG files without any software. You simply upload your images and the website does everything for you on the backend.
You can’t see any of the source code but the optimization is powered by Kraken. You’ll be blown away how small your images can get when you run them through this tool.
It accepts any common image filetype like PNGs, SVGs, TIFFs, even PSDs or existing JPG files. Once you upload a file(or files) you’ll see each one processed in real time.
The final results display in a table with the image’s original file size next to it’s converted file size. I uploaded a 560KB JPEG and it shrunk down to 256KB in a matter of seconds. That’s a 46% decrease in file size just by using this webapp!
Also instead of uploading from your computer you can import images from your cloud storage accounts for Dropbox, Google Drive, or Box.com. Images can be imported directly, converted, then either saved locally or re-uploaded to your cloud accounts.
When you upload multiple images you also get the option to download all of them in one large ZIP file. This can save a lot of time in the long run, especially if you’re working with large batches of images.
Jpeg.io is free, easy to use, and one of the most practical methods for reducing image filesizes on the web. Since you can only get output files in JPEG you should make sure that you’re OK using that filetype in your final project.
But with the option to upload layered docs like EPS and PSD files, this is truly a one-of-a-kind application that should be a staple for site optimization and image compression.
