Flameshot is a free and open-source, cross-platform screenshot tool with built-in editing features. Users select an area to capture, then annotate it with arrows, text, blur, borders and counters before saving. It offers a configuration dialog, a command-line interface for scripting, and downloads for Windows, macOS and Linux.
G'MIC is a full-featured open-source framework for digital image processing, distributed under free software licenses. It processes generic image datasets, from 1D signals to 3D+t volumetric sequences, and offers several interfaces: a command-line tool, the G'MIC-Qt plug-in for image editors, a C++ library, an online web service and the ZArt video tool.
DocFetcher is an open-source desktop search application that searches the contents of files stored on a computer. It runs on Windows, Linux and macOS under the Eclipse Public License. Users create indexes for folders to search, and results include a text-only preview with highlighted matches and filters by filesize, file type and location.
Twine is an open-source tool for telling interactive, nonlinear stories. Simple stories can be made without writing code, and stories can be extended with variables, conditional logic, images, CSS and JavaScript. Twine publishes directly to HTML, and creations are free to use, including for commercial purposes. It is available as a desktop app or in a browser.
CompressImage is a browser-based tool for compressing JPEG, PNG, GIF and WebP images. The site states that compression runs offline in the browser and that images are not uploaded to a server. It offers settings for quality, maximum width or height, conversion to WebP, metadata stripping and IDs removal. Files can be downloaded individually or together as a ZIP.
ImageFoo is an image optimizer that compresses images using advanced algorithms that detect and analyse images, then compresses them to a quality chosen by the user. Users drag or click to add images and hit optimize. It supports both Windows and Android devices and compresses multiple types of images.
RIOT is a free image optimizer for Windows, macOS and Linux. It offers automatic image optimization, multi-core batch processing and a live original-versus-optimized preview. The project supports JPEG, PNG, WebP and GIF, and its first public release was in 2008.
