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.

imgproxy - Fast and secure standalone server for resizing and converting remote images

•    Go

---

imgproxy is a fast and secure standalone server for resizing and converting remote images. The main principles of imgproxy are simplicity, speed, and security. imgproxy can be used to provide a fast and secure way to replace all the image resizing code of your web application (like calling ImageMagick or GraphicsMagick, or using libraries), while also being able to resize everything on the fly, fast and easy. imgproxy is also indispensable when handling lots of image resizing, especially when images come from a remote source.

Sharp - High performance Node.js image processing

•    Javascript

---

The typical use case for this high speed Node.js module is to convert large images in common formats to smaller, web-friendly JPEG, PNG and WebP images of varying dimensions.Resizing an image is typically 4x-5x faster than using the quickest ImageMagick and GraphicsMagick settings.

lilliput - Resize images and animated GIFs in Go

•    C++

---

lilliput resizes images in Go. Lilliput relies on mature, high-performance C libraries to do most of the work of decompressing, resizing and compressing images. It aims to do as little memory allocation as possible and especially not to create garbage in Go. As a result, it is suitable for very high throughput image resizing services.

Fast Image (JPG) Resizer for Java

•    Java

---

The quot;Fast Image Resizer for Java Toolquot; has following features: resize all JPEG/JPG images of a directory, generate web galleries, store resized images in a ZIP file, add text or image watermark. The Tool is available in German and English.

imaginary - Fast, simple, stateless HTTP microservice for high-level image processing with first-class support for Docker & Heroku

•    Go

---

Fast HTTP microservice written in Go for high-level image processing backed by bimg and libvips. imaginary can be used as private or public HTTP service for massive image processing with first-class support for Docker & Heroku. It's almost dependency-free and only uses net/http native package without additional abstractions for better performance.Supports multiple image operations exposed as a simple HTTP API, with additional optional features such as API token authorization, gzip compression, HTTP traffic throttle strategy and CORS support for web clients.

react-native-image-resizer - 🗻 Resize local images with React Native

•    Objective-C

---

A React Native module that can create scaled versions of local images (also supports the assets library on iOS). Note: on latest versions of React Native, you may have an error during the Gradle build on Android (com.android.dex.DexException: Multiple dex files define Landroid/support/v7/appcompat/R$anim). Run cd android && ./gradlew clean to fix this.

Batch Image Converter Features: 1. Convert multiple images. 2. Rename images while converting. 3. Resize images. Supported Formats: jpg png bmp gif

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.

grunt-contrib-imagemin - Minify PNG and JPEG images.

•    Javascript

---

Select optimization level between 0 and 7. The optimization level 0 enables a set of optimization operations that require minimal effort. There will be no changes to image attributes like bit depth or color type, and no recompression of existing IDAT datastreams. The optimization level 1 enables a single IDAT compression trial. The trial chosen is what OptiPNG thinks it’s probably the most effective. The optimization levels 2 and higher enable multiple IDAT compression trials; the higher the level, the more trials.
