You already know the big free-image sites. Unsplash, Pixabay — I rounded those up last time. This is a different shelf. Smaller, more specialized, the kind of thing you reach for mid-project: 3D icons, PSD mockups, Figma UI kits, open-source fonts. Eight of them. I picked on one thing above all — whether the license is clean.
One note up front. “Free” doesn’t mean the same thing twice. Some of these you use with no strings at all; some give you only a slice for free; some let you use the file but not resell it. It varies by site, so I’ve put the condition next to each one.
Start with the cleanest licenses
The easiest license to live with is CC0 — the maker waived copyright, so you use it commercially with no credit. Two of these are exactly that.
3dicons (3dicons.co) is a 3D icon library. Two hundred designs rendered from several angles, so it runs past 1,500 files, all CC0. Vijay Verma built it, and it has crossed ten million downloads. There’s a paid Pro editor for recoloring and re-angling online, but the library you download is free, no conditions attached.
Khagwal 3D (3d.khagwal.com) is also CC0 3D, but illustrations rather than icons — around 45 of them, in five colorways and five angles. Nitish Khagwal made them in Blender, and you duplicate them straight from the Figma community. One wrinkle: the license is CC0, so legally anything goes, but the maker asks that you not redistribute or sell them. That’s a request, not a rule.
If your icons lean line-style, look at css.gg. It is 704 icons in pure CSS, SVG, and Figma, under the MIT license — which also means no attribution and commercial use is fine. A developer named Astrit built it, and you pull it in with one line of npm or a CDN. Handy if you work with icons in code.
Icons, mockups, fonts — know the line
From here the tools are free with a boundary. Know the boundary and you’re fine.
Lineicons (lineicons.com) is a line-icon library of roughly 28,000 icons. The catch is that only a slice is free. The base set ships under MIT, so you can use it commercially without credit, but the full library and the extra styles sit behind Pro. The free set covers most jobs — just check whether the icon you need is in the free column first.
For mockups, Mr.Mockup (mrmockup.com) hands you PSD mockups of t-shirts, business cards, device screens, and the like, free. Commercial use is allowed and no attribution is needed. One condition: you can’t resell or redistribute the raw PSD as-is. Opening it, dropping your design in, and shipping the result is fine. The nicer mockups are paid, around $29 to $49 each.
For fonts, I’d point you to Collletttivo (collletttivo.it) — yes, three L’s. It’s Italy’s first open-source type foundry, started in Milan in 2017, and every typeface ships under the SIL Open Font License. OFL lets you use fonts commercially, with two rules: you can’t sell the font file on its own, and if you modify and redistribute one under a reserved name, you rename it. Setting the font in a site or in print trips none of that.
The “curated” sites are convenient, but the conditions scatter
The last two are a different animal. They don’t make the assets — they gather good ones from around the web and point you at them.
Figma Elements (figmaelements.com) collects Figma UI kits, icons, mockups, and design systems. UI Store Design (uistore.design) hand-picks free UI kits — 648 of them, across Figma, Sketch, XD, and Webflow. Both are genuinely useful.
Here’s the point I made last time, again. A curator isn’t the one granting the license. The same way a font aggregator didn’t draw the font, these sites didn’t make the resource — they linked to it. Figma Elements isn’t even affiliated with Figma. So when you grab something you like, check what the person who actually made it asked for. Curation saves you the hunt; it doesn’t erase the conditions.

How I’d pick
In a hurry and don’t want to think about conditions? Start with CC0. 3dicons and Khagwal you just download and use. For icons, css.gg being MIT keeps it easy, and if you need more line styles, the free Lineicons set. Mockups from Mr.Mockup, fonts from Collletttivo. Use the two curated sites to browse, but check the original terms when you download.
For what it’s worth, this blog barely touches stock or mockups. The cover image on each post is a title card we make ourselves. When an icon is needed, I start from open-source sets that carry no attribution. Picking the no-strings option up front beats hunting for something pretty and getting tied to a credit line. The bigger picture on free images and fonts is in the earlier piece.
