At Argo, we’re boaters first. We know that the data you collect on the water—your routes, tracks, and favorite waypoints—represents more than just coordinates. It represents real time, real fuel, and real experience.
But we also know a frustrating truth: this data doesn’t always “fit” the way you need it to.
Maybe you recorded a high-resolution track that’s too “heavy” to share. Maybe you built a complex route that exceeds the memory limits of your Garmin or Raymarine chartplotter. Or maybe you have a “Track” that your device insists must be a “Route.” That’s why we created SimplyGPX by Argo—a dedicated utility designed to reshape your GPS data to fit the task at hand.
The Problem: One Size Doesn’t Fit All
GPS devices are excellent at collecting data, but they often collect more than most hardware can comfortably handle. When you try to move that data between systems, you quickly run into “The Size Wall”:
- Hardware Limits: Most chartplotters have a hard cap on points per route. If your file is too big, the unit might reject it outright or, worse, fail mid-voyage without explanation.
- Digital Clutter: High-density tracks often contain “jitter”—clusters of points created while drifting or at the dock—that add bulk without adding clarity.
- Format Mismatch: Sometimes you have a recorded Track of where you went, but you need it to behave like a Route you can follow (or vice versa).
SimplyGPX is the tailor for your data. It bridges the gap between raw recordings and reusable navigation.
How SimplyGPX Makes it “Fit”
We built SimplyGPX around four essential operations to solve the most common GPX headaches:
1. Fit to Your Hardware (Point Reduction)
If your helm unit only accepts 250 points but your file has 2,000, SimplyGPX uses intelligent algorithms to “thin” the data. It removes redundant points while preserving every critical turn and waypoint. You get a file that fits your plotter perfectly without sacrificing the shape of your path.
2. Fit to Your Navigation Style (Route ↔ Track Conversion)
This is a game-changer for cross-platform compatibility. Some devices handle “Tracks” (the recorded trail of where you’ve been) differently than “Routes” (the planned path of where you’re going). SimplyGPX allows you to swap these formats instantly. Turn a Sunday cruise into a plan for next weekend, or turn a complex planned route into a lightweight track.
3. Fit to Your Segment (Auto-Splitting)
Some trips are simply too long for one file. SimplyGPX can automatically split a massive track into sequential segments (e.g., Part 1, Part 2, Part 3). By using our “Overlap” feature, you ensure the end of one segment matches the start of the next for seamless navigation.
4. Fit to Your Standards (Simplification & Denoising)
Strip away the GPS “noise” from when you were idling or slow-trolling. Our simplification slider lets you clean up the jitter, leaving you with a professional-looking line that accurately reflects your actual travel.
A Tool for the Entire Boating Community
Argo is committed to making navigation better for everyone. That’s why SimplyGPX is free and standalone. You don’t need an Argo account to use it, and your data never leaves your computer—all processing happens locally in your browser for total privacy.
Whether you’re an Argo power user or a navigator using dedicated hardware, SimplyGPX is here to make sure your data works as hard as you do.
Why use SimplyGPX?
- Universal Compatibility: Works with GPX files from any source (Navionics, Garmin, Raymarine, etc.).
- Privacy First: Your secret spots and favorite fishing grounds stay on your machine.
- Zero Cost: A purpose-built utility from the Argo team to support the broader boating community.
Make Your Data Fit
Don’t let “File Too Large” or “Memory Full” errors stop your next adventure. Before you head to the boat, run your plans through SimplyGPX and make sure your data is sized exactly for the task.
