Questions

Good to Know.

Is my uploaded photo sent anywhere?
No. It's read locally in your browser using the File API and never uploaded to a server. Refreshing or closing the tab clears it completely.
Is the price shown a real quote?
No — it's a transparent estimate based on typical flex-LED neon pricing (size, text length, backing and add-ons), calculated the same way every time with no inflated "original price" or fake discount. It's meant as a ballpark, not a binding quote from any manufacturer.
What do I get when I download?
A PNG image of exactly what's on your screen — your text, glow, backing and background scene — rendered at 2x resolution for a crisp export.
Can I use my own font or wall photo?
You can upload any photo as the backdrop. Fonts are currently limited to the ten curated neon-style styles in the panel, chosen to render clean glow at any size.
Does this build or sell physical signs?
No — Neon Builder is a free, independent design and mockup tool only. It isn't affiliated with any single sign manufacturer. Use "Copy Design Summary" to take your finished spec to whichever shop you choose to buy from.
