Apps with 'PNG Optimization' feature

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).

pngquant is a command-line utility and a library for lossy compression of PNG images.

Make your website faster and save bandwidth. TinyPNG optimizes your PNG images by 50-80% while preserving full transparency!.

Oxipng is a multithreaded lossless PNG compression optimizer in Rust. It can be used via a command-line interface or as a library in other Rust programs.

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.

OptiPNG is a command-line PNG optimizer that recompresses image files to a smaller size, without losing any information. This program also converts external formats (BMP, GIF, PNM and TIFF) to optimized PNG, and performs PNG integrity checks and corrections.

-Combines PNGOUT, OptiPNG, and DeflOpt to create the smallest PNGs -No image quality is lost — only file size -Converts JPG, GIF, TIFF, and BMP files to PNG -Ultra-configurable

PNGGauntlet is a .NET program that uses Ken Silvermans PNGOUT, OptiPNG and DeflOpt to optimize PNG fil.

C++ file optimizer. It supports PNG, JPEG, GZIP, and ZIP files.

Minuimus is a file optimizer utility script: You point it at a file, and it makes the file smaller without compromising the file contents.

TruePNG is one of the most advanced PNG optimizers available. It does the most exhaustive checks for reductions, that lets it to optimize further, even if it uses a less efficient compression algorithm than others tools.

You can use PNGOUTWin, an easy-to-use PNG optimizer, to create smaller image files and speed up your website, reach more potential customers, and decrease your bandwidth costs. You can convert and compress to PNG from TIFF, GIF, BMP, and other formats, or optimize your existing...

Pngyu is simple PNG image file compression tool. Pngyu use pngquant as a compression engine.

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.

Color quantizer is a small program allows you to easily optimize images for web.

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.
