FAQ
Is PhotoSTL a free image to STL converter?
30 free credits (≈3 drafts) when you sign in (Google or magic link) — no card required for the trial. After that, Hobby is $9 for 1,500 credits (~$0.06 per draft on our price list). We do not offer unlimited no-account AI conversions.
Why do some free converters need no account?
Many run a local heightmap or silhouette extrude in the browser. That is free forever for reliefs and logos, but it is not single-image AI full 3D. PhotoSTL’s free tier covers AI mesh drafts, which cost GPU time — hence credits after sign-in.
What do I get for free?
30 credits ≈ 3 image to 3D drafts at today’s rate. Each generate uses 10 credits. You can re-download that draft’s STL/3MF anytime. Free regenerate only if the mesh looks incomplete.
Can I try without a credit card?
Yes. Sign in on photostl.com with Google (One Tap or OAuth) or a magic-link email from an allowed major mailbox domain. No card for the trial.
