darktable

This open source alternative to Adobe’s Lightroom manages your digital negatives in a database, lets you view them through a zoomable light table and enables you to develop raw images and enhance them.

digiKam

Photo management app rivals Lightroom with ability to organize and optimize. Can handle libraries of more then 100,000 images. Processes raw files, edits JPEGs and publishes to social media

Gifski

Convert videos to high-quality GIFs.

Giphy Capture

Capture videos, or anything else that moves on your screen, as an animated gif with one-click stop and start. Allows for precision editing and sharing with friends.

Hugin

Assemble a mosaic of photographs into a complete immersive panorama, stitch any series of overlapping pictures and much more.

iBooks Author

Create and publish multi-touch books for iPad with this free tool from Apple. Start with a template and use drag-and-drop to customize it with photo galleries, movies, slideshows and 3D objects. Preview it on an iPad, then submit it to the iBookstore.

Iconverter

Choose a program and convert its icon to an image. Formats include PNG, TIFF, JPG, GIF, ICNS and ICO. Batch processing is available and you can decide on the background colour. This tool is invaluable if you need to post the image of an icon on a website — in a software review, for example. Unfortunately, it seems to have been abandoned by the developer, but you can use the link below as a direct download from thriftmac.

ImageOptim

Drag and drop .jpeg, .png and .gif images and see them instantly slim down. My pic of a baby relaxing in a tub on a hot day lost 15 per cent of its bulk. This open source app works by finding the best compression parameters and removing unnecessary comments and colour profiles. Which is just what you want to make websites load faster.

Linear

Use a ruler to measure stuff on your screen in pixels or ems. Make as many rulers as you like. Great for web designers.

Meme Generator

Have mindless fun taking bizarre photos that have been circulating around the Internet — annoying Facebook girl, for example — and applying your own slogans to them. Or, as the website version puts it: “Bluntly offensive statements and careless advice with animal icons.”

Scribus

This open source alternative to the likes of QuarkXPress and InDesign supports CMYK colour, separations, ICC colour management and versatile PDF creation. It may take some getting used to, but there is a strong community of users to offer support.

System Color Picker

A nice app version of the color picker that comes with your Mac. It can be invoked from the menu bar or record your own shortcut. It gives values in hex, hsl and rgb.

Th-MakerX

Drag and drop one image, many images or a folder of images to be resized and output as jpeg or png. Options for margin, canvas, destination, resolution, watermark and more.

Windowed

Stripped down mobile browser allows you to upload photos to Instragram directly from your Mac desktop.

XnConvert

Batch image-converter and resizer supports common formats such as JPG, PNG, TIFF, GIF, Camera RAW, JPEG2000, WebP and OpenEXR in addition to over 500 other image formats. Operations include rotating, adding watermarks, adding text, and adjustments for brightness, shadows and more.
