Neon Sign Designer: Free Online Tool for CNC Files, DXF Export & Client Mockups

Design neon signs in the browser and export the files you need for production: SVG for laser cutting acrylic, DXF for CNC routing and tube bending, preview PNG for client sign-off. No software to install, no account required.

Why Production Shops Use This Tool

Before any acrylic gets cut, you need several files per job: a sign layout, a centerline path for LED flex routing, an outline file for the laser cutter to shape the acrylic backing board, and a preview to send the client. Most shops pull those from different programs, and something goes wrong in the handoff almost every time, a scaling issue, a wrong file format, or time wasted rebuilding the same design twice.

This is a neon sign design tool for that workflow. Not for social media graphics or decoration mockups. The outputs are DXF and SVG files your machines can read, plus a preview PNG for the client. All from the same design.

Works in the browser, nothing to install

Open it on any computer or tablet you have in the shop. No software to buy, nothing to install, no conflicts with your existing CAD setup.

One design gives you the full file set

Design the sign once and download everything: centerline DXF for CNC groove routing, SVG for the laser cutter, filled outline DXF for reference, shaped border SVG for the backing board, and a PNG mockup for the client. No rebuilding the same job in a second program.

Free to use, no account needed

Open the page and start working. No sign-up, no trial, no exports locked until you pay.

How It Works

Step 1: Design Your Sign

Type the sign text, pick a font, set the neon color. The canvas shows a live preview as you go. For logo work or anything that is not standard text, switch to the Draw Centerline editor and trace the path by hand on the canvas.

Step 2: Generate the Acrylic Backing Outline

Once the design is set, a smooth outer border is generated automatically around it. You can extend this border up to 50mm from the design edge. That outline becomes the laser cut file for your acrylic backing board. Most shops draw this by hand in a vector editor for every job. Here it is done in one click.

Step 3: Export Your Production Files

Step 4: Cut, Route, Mount

Load the DXF into VCarve, Aspire, or RDWorks. Load the SVG into LightBurn or RDWorks. Cut the acrylic backing board, route the LED flex channels, mount the strips. DXF files are exported in a standard format and stay fully editable, so you can scale the design to your required production dimensions in VCarve, Aspire, RDWorks, LightBurn, or AutoCAD before machining.

Export Formats

Single Line DXF: Centerline for CNC Routing and Tube Bending

One path, the centerline of the letter or shape, representing the exact route your LED flex strip or glass tube follows. Load it into VCarve, Aspire, or RDWorks and build the groove toolpath from it. For glass neon, plot it at 1:1 scale and use it as the bending pattern on the bench. Worth noting: if you send a filled outline DXF to the CNC router, it cuts the letter boundary, not the channel groove. The single line DXF is the file the router needs.

SVG: Laser Cutting Acrylic Backing Boards

Closed-path SVG, ready to open in LightBurn, RDWorks, or LaserCAD. Set your cut speed and power for the acrylic thickness you are running and go. No path repair needed.

Smooth Stroke Border SVG: Shaped Backing Board Boundary

A separate SVG of the outer boundary of the sign. This is what you use to cut the acrylic backing board to its finished contour shape, so the board matches the sign rather than being a plain rectangle with the neon sitting on top of it.

Filled / Outline DXF: Reference and Plotting

The full letter outline as a DXF file. Good for dimensional checks, proofing prints, or shops that route from outline paths rather than centerlines.

Client Preview PNG

A rendered preview of the sign glowing in your chosen color on a dark background. Send it by WhatsApp or email before you cut anything. Much easier to make changes at this stage than after the acrylic is already cut.

Common Problems This Tool Solves

Fonts do not give you a centerline path
Every font is a closed outline shape. To get the single line DXF your CNC router or tube bender needs, you have to draw the centerline yourself. The Draw Centerline editor is built for exactly that.
The acrylic backing board file is always a separate task
Getting a clean laser cut file for the backing board usually means redrawing the sign outline somewhere else. Here it comes out of the same design automatically as a separate SVG export.
Manually tracing a border around the design for the acrylic cut
Drawing a smooth offset border around a neon sign in a vector editor takes time, especially on jobs with curved lettering. The backing board outline here is generated automatically with a configurable border up to 50mm, ready to send straight to the laser cutter.
Client mockups mean opening another program
The preview PNG comes from the same design session. No switching apps, no rebuilding the layout in a mockup tool just to get an image to send.
DXF files importing at the wrong scale
DXF unit mismatches are a common problem when files move between design software and CNC machines. These files export in a consistent format that loads at the correct scale in VCarve, Aspire, RDWorks, and AutoCAD.
Paying for CAD software just to export DXF
A lot of shops keep a CAD or vector software subscription running just for the DXF export step. All five export formats here are free, with no account or license required.

Frequently Asked Questions

What is the difference between a single line DXF and a filled outline DXF for neon signs?

A single line DXF is one path tracing the centerline of the letter or shape, with no fill. A filled outline DXF is the closed boundary of the letter with inner and outer edges. CNC routers and tube bending guides need the centerline because that is what defines the routing groove for LED flex channels and the bending path for glass tubes. If you send a filled outline to the CNC router, it cuts the letter edge, not the channel.

What CNC and laser software can read these files?

DXF exports are standard AutoCAD-format files that open in VCarve Pro, Aspire, RDWorks, LightBurn, AutoCAD, CorelDRAW, and Inkscape. SVG exports work with LightBurn, RDWorks, LaserCAD, and Inkscape.

Can I use the Draw Centerline editor for logo-based neon signs, not just text?

Yes. The Draw Centerline editor works for any path you want to draw on the canvas, whether that is text, a logo, or a custom shape. Draw it, then export directly as a single line DXF.

Does this work for glass tube neon as well as LED flex neon?

Yes. The single line DXF works for both. LED flex shops use it as the CNC routing path for the acrylic channel. Glass tube benders print it at 1:1 scale and use it as the bending pattern on the bench, the same way a hand-drawn pattern would be used.

Is the tool free to use?

Yes, fully free with no login. All export formats (Single Line DXF, Filled DXF, SVG, and Preview PNG) are available without an account.
