Free imagery, icons and fonts

The agency calls this the premier source of public domain wildlife imagery, and it is the obvious first stop for a conservation organization. Free to reuse for any purpose; credit to the photographer and the Service is asked for, not required

Start here for any US species photo, since nothing you take will need permission

Public domain marine imagery by group: fish and sharks, corals and invertebrates, dolphins, sea turtles, seals. NOAA's National Ocean Service runs a separate coastal gallery at oceanservice.noaa.gov/gallery

Search by species group when you need a free marine animal photograph

Photos, video and audio across wildlife, landscapes, geology and water science. Public domain unless an item says otherwise, with the crediting format on the page

Grab landscape, geology and water imagery, plus audio you can drop into a video

Earth observation and Landsat imagery for habitat and land-cover context, not close-up wildlife: deforestation before and after, coastline change. Free with a source acknowledgement. The NASA insignia itself is protected separately

Pull before-and-after satellite views to show habitat loss a ground photo cannot

Ocean and marine wildlife photography from The Ocean Agency, endorsed by the UN Ocean Decade and curated for conservation communication rather than incidentally licensed. Free for non-commercial use

Use it for outreach rather than anything commercial, since the license stops there

Enormous community archive, but most of it is attribution and share-alike, so a crop for a banner has to carry the same license forward. Good for embedding with credit, awkward if you want to edit and rebrand

Check the license on each image, because share-alike terms will follow your crop

Thousands of nature and conservation icons in SVG, PNG, EPS and icon-font formats. Free with attribution, paid to drop the credit line. The one to reach for when building an infographic or a threat-category key

Build one consistent icon set for threats or habitats instead of mixing sources

Web and desktop typefaces, most of them under the SIL Open Font License, free for commercial use with no attribution needed

Pick two typefaces and stay with them, which is most of what a house style needs

The license itself, from the nonprofit that wrote it. Worth reading once: it allows logos, books, apps and 3D prints freely and only forbids reselling the font files

Read it once before putting a font in a logo, so you know what is permitted

General free stock photography with large wildlife and nature collections, no attribution required. Not vetted for conservation framing or species accuracy, so confirm what the animal actually is before you caption it

Use it for mood and landscape shots, never where a species must be identified

Free stock photos and video, commercial use allowed, no attribution required. Same caveat as Unsplash on species accuracy

Search here when you need video rather than stills and have no budget

Free stock photos, video, illustrations and vectors under a blanket permissive license. Useful as a fallback when a specific species or region is not in the government galleries

Try it when a specific region or species is missing from the government galleries
