IMAGEmini is described as ', a powerful photo resizer and optimizer, allows you to optimize all your photos by 80% ~ 20% comparing to their originals while keeping their original resolution, quality and png, jpg, gif formats' and is an app in the Photos & Graphics category. There are more than 25 alternatives to IMAGEmini for a variety of platforms, including Windows, Mac, Online / Web-based, Linux and Wordpress. The best alternative is ImageMagick, which is both free and Open Source. Other great apps like IMAGEmini are ImageOptim (Free Personal, Open Source), RIOT - Radical Image Optimization Tool (Free), TinyPNG (Freemium) and PNGGauntlet (Free).
ImageMagick is a software suite to create, edit, and compose bitmap images. It can read, convert and write images in a variety of formats (about 100) including GIF, JPEG, JPEG-2000, PNG, PDF, PhotoCD, TIFF, and DPX.
ImageOptim is excellent for publishing images on the web (easily shrinks images “Saved for Web” in Photoshop). It's useful for making Mac and iPhone/iPad applications smaller (if you configure Xcode to allow better optimization).
Saving images for web/email/other media with the best compression ratio and quality is a difficult task if you don’t have the right tools. Choosing the right format then choosing the right parameters are the key factors of smaller files.
TinyPNG uses smart lossy compression techniques to reduce the file size of your PNG files. By selectively decreasing the number of colours in the image, fewer bytes are required to store the data. The effect is nearly invisible but it makes a very large difference in file size!
Experimental, fast Web PNG/JPG optimizer which offer lossless, visually lossless or lossy compression. it performs image reductions over iterations thanks to recursive multi-processing and multithreading systems.
PngOptimizer compresses graphics files and removes extra, unnecessary data without affecting quality. It will update PNG files or converting BMP, GIF or TGA files to the PNG format using simple drag-and-drop.
PhotoBulk is easy-to-use bulk image editor that lets you add text/image watermark, resize, and optimize hundreds and thousands of images or photos in just one click. Just drag and drop your images onto the app, choose desired actions and press start button. Voila!
