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.

vips - Go Bindings for Vips (a super fast image processor)

•    Go

---

This package is powered by the blazingly fast libvips image processing library, originally created in 1989 at Birkbeck College and currently maintained by JohnCupitt. The typical use case for this high speed package is to convert large images of many formats to smaller, web-friendly JPEG, PNG images of varying dimensions.

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.

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.

image-resizer - On-the-fly image resizing using Node.js and GraphicsMagick. Heroku Ready!

•    Javascript

---

image-resizer is a Node.js application that sits as a custom origin to your CDN and will resize/optimise images on-the-fly. It is Heroku ready, but can also be deployed easily to any cloud provider (has been used with success on AWS). The primary goal for this project was to abstract the need to set image dimensions during the upload and storage phase of images in a modern web application.

Aqua-Resizer - Resize WordPress images on the fly

•    PHP

---

This small script will allow you to resize & crop WordPress images uploaded via the media uploader on the fly. It relies on WP's native functions to resize the images, and checks if there is an already resized version of the image so that it won't be wasting your server's resources to regenerate the images. There are a couple of image resizing scripts out there that already have this function. Some authors simply use the add_image_size() function to define custom image sizes that will be generated for each image uploaded via the media uploader. I mostly find these methods somewhat a little complicated to use, or having some limitations or too resource intensive.

gulp-responsive - gulp-responsive generates images at different sizes

•    Javascript

---

gulp-responsive depends on sharp. Sharp is one of the fastest Node.js modules for resizing JPEG, PNG, WebP and TIFF images. If you are using Mac OS then before installing gulp-responsive you should install the libvips library. Further information and instructions can be found in the sharp installation guide.

serverless-image-resizing - CloudFormation template to resize images on-the-fly using Amazon API Gateway, AWS Lambda, and Amazon S3

•    Javascript

---

Resizes images on the fly using Amazon S3, AWS Lambda, and Amazon API Gateway. Using a conventional URL structure and S3 static website hosting with redirection rules, requests for resized images are redirected to a Lambda function via API Gateway which will resize the image, upload it to S3, and redirect the requestor to the resized image. The next request for the resized image will be served from S3 directly.Use the Amazon Linux Docker container image to build the package using your local system. This repo includes Makefile that will download Amazon Linux, install Node.js and developer tools, and build the extensions using Docker. Run make all.
