Iconstack

What is Iconstack?

Iconstack is a free icon library and search tool for finding and downloading SVG icons. It offers a large collection of icons from multiple popular icon sets, including Material, Tabler, Phosphor, Lucide, Remix, and Bootstrap-related sources, and supports downloading assets in several formats.

The core purpose is to help designers and developers quickly locate the right icon, adjust basic presentation details like color and stroke, and download the result for use in projects without requiring a login.

Key Features

Search a large free library of SVG icons to quickly find icons by name and/or set, reducing time spent browsing manually.
Browse and download icons sourced from well-known icon collections (e.g., Material, Tabler, Phosphor, Lucide, Remix, Bootstrap and more).
Customize visual properties such as color and stroke before downloading, so icons can match the styling of a UI.
Download icons in multiple formats, including SVG, PNG, and XML, depending on how you plan to use them.
No login required, making it straightforward to use the tool ad hoc while building or iterating on a design.

How to Use Iconstack

Open Iconstack and use the search to locate an icon you need.
Review the available results and select the icon that matches your use case.
If necessary, customize the icon’s color and stroke.
Download the icon in the format you need (SVG, PNG, or XML) and place it into your project.

Use Cases

UI development: Find an icon that matches common UI actions (e.g., navigation, settings, status) and export SVG/XML assets to integrate directly into components.
Design system styling: Customize icon color and stroke so icons align with a brand’s color palette and visual weight.
Marketing/landing pages: Download PNG versions for static assets where SVG integration may be unnecessary.
Rapid prototyping: Use the no-login flow to grab icons quickly while iterating on mockups or wireframes.
Cross-tool handoff: Export SVG or XML depending on whether the next step is vector editing or importing into another workflow.

Alternatives

Other SVG icon libraries (general approach): Use a dedicated icon gallery with search and direct downloads; differences typically come down to available icon sets, customization options, and supported export formats.
Icon packs with theming support: Choose an icon pack that emphasizes consistent styling and built-in variants; workflow may focus more on selecting from predefined weights rather than ad hoc customization.
Design tool icon libraries: Use an integrated icon library inside a design tool for faster design-to-export; the primary difference is where you customize and export (within the design environment vs. a standalone icon site).
Developer-focused icon packages: Opt for icon distributions geared toward codebases (e.g., imports/consumption in projects); these may reduce manual download steps but vary in how they handle color/stroke customization.
