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).

Reduce PNG file sizes by 50-80% using smart compression while maintaining transparency. TinyPNG optimizes images to speed up websites and save bandwidth.

-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.

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.

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.

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.

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

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

ShortPixel is arguably the top WordPress image optimization plugin: simple to set up, it can automatically optimize both your old and new images, as well as PDF files.

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

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

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.

Pngcrush is an optimizer for PNG (Portable Network Graphics) files. It can be run from a commandline in an MSDOS window, or from a UNIX or LINUX commandline.

Clever Compress is a free online tool for image compression and conversion. Optimize JPEG, PNG, WebP, and more directly in your browser, ensuring full GDPR compliance. No images are sent to servers, making it fast, secure, and reliable.
