What it is
DummyLogo is a free SVG placeholder logo generator. Give it a company name and it returns a square, self-contained company mark you can use in wireframes, product screens, slide decks, and frontend prototypes.
Unlike a random color square, each result looks like a real identity system: a geometric mark, a wordmark, or a lockup, set in one of 14 typefaces and 23 palettes. Unlike a human-designed logo, the output is deterministic. The same name, seed, variant, and size tier always produce the same file.
The default seed is oak-7. Embed /api/logo?name=Northwind or download the SVG. See the generator notes or the HTTP API.
9 styles, 38 marks, 24 variants, and sizes from 32 to 2048 pixels.
The same company name, seed, variant, and size tier always produce the same SVG. The default seed is oak-7.
Choose mark, lockup, stacked, wordmark, badge, monogram, crest, seal, or split — or let auto pick a style that fits the name.
Icon (≤64px), compact (≤128px), and full tiers change composition so 32px favicons stay readable and 1024px lockups keep their wordmarks.
Text is converted to paths and fonts are not required at display time. Safe to drop into Figma, HTML <img> tags, or email mockups.
GET /api/logo?name=Northwind returns an SVG logo. GET /random-headshot?size=64 returns a random avatar JPEG; add round=1 for a circular PNG. Pretty paths, JSON metadata, CORS, and cache headers are built in.
Names like Harbor Legal, Helix Labs, or Fraiche Cafe bias toward related marks — scales, hexes, leaves — instead of a generic icon every time.
Step 1
Type any brand name. Optional descriptors such as Labs, Capital, or Legal become a subtitle.
Step 2
Choose 32–2048px, one of 9 styles (or auto), and one of 24 variants.
Step 3
Keep seed=oak-7 (or your own string) so the logo stays identical. Download the SVG or embed the API URL.
Fill dashboard sidebars, login screens, and marketing comps with believable brand marks instead of gray boxes.
Show how a header, favicon, and app icon behave at 32, 64, 128, and 256 pixels from one seeded name.
Download an SVG or paste a stable URL so placeholders stay consistent across files and revisions.
Point <img src> at the API. Same query string, same logo — useful for Storybook, tests, and seeded demos.

DummyLogo is a free placeholder logo generator that creates realistic, square SVG company logos for mockups. You give it a company name and an optional seed; it returns a deterministic mark, wordmark, badge, crest, or lockup that you can download or embed.
Yes. The studio and HTTP API are free to use for mockups, prototypes, documentation, and design comps. Generated logos are placeholders, not real trademarks.
Yes. DummyLogo hashes name + variant + seed + size tier. The same inputs always produce the same SVG. Omitting the seed uses the default seed "oak-7".
Every logo is a self-contained SVG. Letterforms are outlined as paths, so the file does not depend on webfonts when you embed or download it.
Use GET /api/logo?name=Your+Company&size=256, or the pretty path /api/logo/Your-Company.svg. Responses include CORS and cache headers so you can use the URL in an <img> tag or download the SVG into Figma.
Sizes range from 32 to 2048 pixels. Styles are mark, lockup, stacked, wordmark, badge, monogram, crest, seal, split, plus auto. There are 24 variants per name and seed, 38 geometric marks, 14 typefaces, and 23 color palettes.
Yes. GET /api returns a machine-readable spec. GET /api/logo returns SVG logos; GET /random returns a new logo each time; GET /random-headshot returns a random AI avatar for profile mockups. Add meta=1 or format=json for metadata. GET /docs is the human-readable reference.
Use GET /random-headshot?size=64 for a square JPEG avatar, or GET /random-headshot?size=128&round=1 for a LinkedIn-style circular PNG. Each request returns a new face proxied from thispersondoesnotexist.com. Responses include CORS headers for cross-origin <img> embeds.
No. DummyLogo is a placeholder generator for fictional or temporary brands in mockups. It is not a trademark search, identity system, or replacement for a designer.
Generate deterministic square SVG company logos for mockups, wireframes, and prototypes. DummyLogo creates marks, wordmarks, badges, crests, and lockups from a company name and seed — no signup, embeddable via URL or HTTP API.
