Gradia review
Free, open-source Linux app for decorating and marking up screenshots.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Gradia is a free, open-source desktop application for Linux users who want to annotate screenshots and prepare images for sharing. Its ten annotation modes include text, arrows, and censoring, so it covers both explanatory markup and hiding sensitive image content. The app can also initiate screenshots from within its interface, making it relevant to solo users and small teams who want capture and decoration in one desktop workflow. It is a focused option rather than a broader collaboration workspace.
Presentation controls are a notable part of the workflow: users can add optional image or gradient backgrounds and adjust settings such as shadow, padding, and auto-balance. Gradia also converts code snippets into high-resolution images, which suits developers who need to share formatted snippets alongside annotated screenshots. A quick upload flow supports sharing images through services such as Imgur. Those features make the app useful when the goal is to create a polished image and pass it along, but they do not amount to team collaboration; the product is not positioned around shared review or coordinated annotation.
Gradia is distributed as a desktop app, with Flatpak and Snap availability described for the project. Its free, open-source model avoids a paid tier decision, and documentation is the listed support channel. The platform scope is Linux, with no browser extension or team collaboration feature, so people working across operating systems or needing review inside a browser should look elsewhere. Choose Gradia for free Linux screenshot markup, censoring, and presentation adjustments; choose another tool if your workflow depends on cross-platform access or collaborative review.
