Phew - FLIF image viewer and QuickLook plugin for macOS

  •        46

Phew is an open-source FLIF image viewer and QuickLook plugin for macOS. The Free Lossless Image Format or FLIF is a novel lossless image format which outperforms PNG, lossless WebP, lossless BPG, lossless JPEG2000, and lossless JPEG XR in terms of compression ratio.

Crunch - Insane(ly slow but wicked good) PNG image optimization

  •    Python

Crunch is a tool for lossy PNG image file optimization. It combines selective bit depth, color type, and color palette reduction with zopfli DEFLATE compression algorithm encoding using the pngquant and zopflipng PNG optimization tools. This approach leads to a significant file size gain relative to lossless approaches at the expense of a relatively modest decrease in image quality (see example images below). Historical benchmarks with the files included in Cédric Louvrier's PNG Test Corpus versus other commonly used PNG optimization software are available in BENCHMARKS.md.

ImageMagick

  •    C++

ImageMagick is a software suite to create, edit, and compose bitmap images. It can read, convert and write images in a variety of formats (over 100) including DPX, EXR, GIF, JPEG, JPEG-2000, PDF, PhotoCD, PNG, Postscript, SVG, and TIFF. Use ImageMagick to translate, flip, mirror, rotate, scale, shear and transform images, adjust image colors, apply various special effects, or draw text, lines, polygons, ellipses and Bézier curves.


JPNG - JPNG is a bespoke image file format that combines the compression benefits of JPEG with the alpha channel support of a PNG file

  •    Objective-C

In iOS and Mac OS apps there is typically a choice of two image formats: PNG format allows transparency but produces large image files and is unsuited to compressing images like photographs; JPEG is great for creating small files and provides a range of compression qualities to suit the subject matter, but doesn't allow for transparency. JPNG is a new image format that combines the best of both of the other formats. JPNG is not really a format in its own right, it's a simple file wrapper that combines a JPEG and PNG image within the same file. JPEG is used to efficiently compress the RGB portion of the image and PNG is used to store the alpha channel.

Flyimg - Microservice to resize and crop images on the fly

  •    PHP

Image resizing, cropping and compression on the fly with the impressive MozJPEG compression algorithm. One Docker container to build your own Cloudinary-like service.You pass the image URL and a set of keys with options, like size or compression. Flyimg will fetch the image, convert it, store it, cache it and serve it. The next time the request comes, it will serve the cached version.

iOS-WebP - Google's WebP image format decoder and encoder for iOS

  •    Objective-C

Google's WebP image format offers better compression compared to PNG or JPEG, allowing apps to send/retrieve images with smaller file sizes, reducing request times and hopefully provide a better user experience. #Usage Don't forget to #import <iOS-WebP/UIImage+WebP.h>. There are 3 methods in iOS-WebP, converting images to WebP format, converting images from WebP format, and setting an image's transparency.

  •    C++

Gwenview is an image viewer for KDE. Gwenview can load and save all image formats supported by KDE. It can accurately control the way images are scaled. It supports image manipulations like rotation, mirroring, cropping, resizing and red eye reduction. When browsing JPEG images with EXIF information, Gwenview automatically rotates them according to the EXIF Orientation tag.

intense-images - A simple library to view large images up close using simple mouse interaction, and the full screen

  •    Javascript

A stand alone javascript library for viewing images on the full, full screen. Using the touch/mouse position for panning. Here's a demo! You can also play with the code live on CodePen. Intense images is a stand alone library (no jquery, or the likes) so usage is pretty straight forward. All styling of image elements is up to the user, Intense.js only handles the creation, styling and management of the image viewer and captions.

Scrimage - Scala image processing library

  •    Scala

Scrimage is a consistent, idiomatic, and immutable scala library for manipulating and processing of images. The aim of the this library is to provide a quick and easy way to do the kinds of image operations that are most common, such as scaling, rotating, converting between formats and applying filters. It is not intended to provide functionality that might be required by a more "serious" image processing application - such as face recognition or movement tracking.

AmazeKit - AmazeKit is a library for rendering beautiful images in your iOS app.

  •    Objective-C

AmazeKit is an image rendering library for iOS. Its goal is to retain the performance of using .png-formatted images in UIKit classes, while avoiding the chore of creating these images in Photoshop, as well as the extra download size of bundling the images in the app. Images are rendered according to a collection of “image effects,” ranging from a simple gradient or corner radius to blurs, masks, and inner shadows. AmazeKit also offers convenient UIKit support, automatically using the correct images as your controls change size. Retina displays are supported automatically, and AmazeKit aggressively caches rendered images to maintain optimal performance levels. The recommended way to get AmazeKit is to use CocoaPods.

imgp - Multi-core batch image resizer and rotator

  •    Python

imgp is a command line image resizer and rotator for JPEG and PNG images. It can resize (or thumbnail) and rotate thousands of images in a go, at lightning speed, while saving significantly on storage. Powered by multiprocessing, an intelligent adaptive algorithm, recursive operations, shell completion scripts, EXIF preservation (and more), imgp is a very flexible utility with well-documented easy to use options.

pngquant - Lossy PNG compressor — pngquant command and libimagequant library

  •    C

pngquant is a PNG compresor that significantly reduces file sizes by converting images to a more efficient 8-bit PNG format with alpha channel (often 60-80% smaller than 24/32-bit PNG files). Compressed images are fully standards-compliant and are supported by all web browsers and operating systems.This is the official pngquant repository. The compression engine is also available as an embeddable library.
