Frequently asked questions
Answers before you buy.
No hidden small print: operation, limits and future versions are explained clearly.
Is it really a one-time payment?
Yes. Core and Pro are perpetual licenses for the LottiePilot 1.x branch. There is no monthly subscription. A future major 2.0 release may be offered separately without disabling your 1.x version.
Does Free require an account or credit card?
No. Free works without a license key and includes three successful conversions, Preview, Doctor Lite and local Web checks.
What is the main difference between Core and Pro?
Core removes the conversion limit for one-file-at-a-time work. Pro adds creation and editing in Motion Studio, batch automation, full Doctor, protected optimization and Runtime testing.
Can my original file be overwritten?
No. Conversion uses safe output names and Motion Studio exports a new JSON or dotLottie copy. You can undo, redo or return to the loaded document.
Does LottiePilot guarantee compatibility everywhere?
It provides real Web render proof and, in Pro, a native Android device test. On Windows, iOS and React Native remain static analyses: final confirmation requires an external native build.
Can I use my license on two computers?
Yes. Core and Pro are planned with two activations. An internet connection is required for activation; file processing then remains local.
Can I upgrade from Core to Pro later?
Yes. The plan is for you to pay only the difference between the editions: €30 during founder pricing, then €50 at the regular price.
Why are some features marked as partial?
Because complex gradients, some morphs, structured SVG import and a complete state-machine graph still need broader coverage. LottiePilot flags a limit instead of silently flattening or altering your animation.
