iconmonstr is a free icon library by designer Alexander Kahlkopf. Icons come as fill and outline, in SVG and PNG, drawn on a 24-pixel grid. The homepage listed more than 4,700 icons in 316 collections.

Is iconmonstr free for commercial work?

Yes. The license allows commercial and non-commercial use without attribution. You still cannot resell the files, use an icon as a logo, or make the icon set the main thing you distribute. Accept the license on iconmonstr before you download.

When should I skip iconmonstr?

Skip it when you need an MIT set you can redistribute, when the icon has to be a logo, or when you want operating-system icon guidelines. Feather Icons, Heroicons, and Lucide are open SVG sets on Uwarp. Icônes searches several of those sets at once.

What is iconmonstr?

Browse thousands of free fill and outline icons on a 24px grid. Download SVG or PNG for commercial projects under a single-creator license.

What it costs

The catalog is free. The limit is the license, not a checkout.

Free tier: Yes
Pricing summary: Every icon is free for personal and commercial projects, with no attribution required and no paid plan on the site. Alexander Kahlkopf grants a perpetual, non-exclusive, non-transferable single-user license. The icon has to stay part of a larger design. You cannot sell, share, or redistribute the files, use an icon as a logo or trademark, or download the whole library at once. Each download asks you to accept that agreement. The homepage listed more than 4,700 icons in 316 collections when this page was reviewed.

What iconmonstr provides

What the public catalog actually hands you.

Fill and outline pairs
Releases ship both a filled version and a lined version, drawn on a 24-pixel grid.
SVG and PNG
Each icon page offers SVG and PNG, plus inline SVG and Base64 snippets for a page.
A size and color generator
The about page describes a generator for size, color, and background shape before you copy.
Collections and favorites
Icons are grouped into collections. You can mark favorites on the site. There is no bulk zip of the whole library.

How to use iconmonstr

From search to a file you can place in a layout.

Search or open a collection
Start on the homepage and look for a single icon. The set is large, and the style is one designer’s, not an OS guideline.
Accept the license
The site asks you to accept the license before use. Read the ban on redistribution and on using an icon as a logo.
Pick SVG or PNG
Download the file, or copy the inline SVG or Base64 snippet if the icon is going straight into HTML.
Keep the icon inside a larger design
Place it in a UI, document, or ad. Do not resell the file or ship a template whose main asset is the icon set.

Who iconmonstr is for

People who need a few simple icons and a short license, not an npm icon package.

Interface designers
Need matching fill and outline symbols for a screen, without installing a package.
Freelancers on client work
Can use icons commercially without a credit line, as long as the files stay inside the deliverable.
Writers and deck makers
Want a PNG for a slide or a document when SVG is awkward to place.

When iconmonstr is the right pick

Choose iconmonstr when you want one designer’s fill and outline icons as SVG or PNG inside a website, deck, or ad. Skip it when you need to redistribute the files, sell a template whose value is the icon set, or follow an operating-system icon style.

License and catalog notes

Limits that matter after the download.

Custom license, single user: The grant is perpetual and non-transferable. You may adapt an icon. You may not sublicense or pass the file to someone else as a standalone asset.
Not a logo: The license bars use as a logo, trademark, or service mark. The iconmonstr wordmark has the same kind of limit.
No full-library download: The Q&A says a download-all feature is unavailable because it would break the license.
Independent, Germany: Run by Alexander Kahlkopf in Hamburg. The site uses cookie consent, Google Analytics, and ad cookies. There is no paid account.
