Finishing a drawing on the grid is only half the job — you usually need it somewhere else: pasted into homework, dropped into a slide deck, printed, or reopened next week to keep working. The Virtual Grid Paper drawing canvas exports four formats, each suited to a different destination.
This guide explains what PNG, SVG, PDF, and JSON each do, which to pick for a given task, and how the JSON format lets you treat your exports as editable projects rather than finished files.
Key Takeaways
- PNG — a flat image for notes, slides, and messaging.
- SVG — a scalable vector file for design software.
- PDF — a document page for printing or sharing.
- JSON — a reopenable project file that keeps your work editable.
- Exports are generated in your browser and downloaded to your device.

1. The Four Export Formats
When you finish a drawing, the canvas offers four ways to take it with you:
| Format | Type | Best for |
|---|---|---|
| PNG | Raster image | Notes, slides, chat, quick sharing |
| SVG | Vector image | Design tools, infinite scaling |
| Document | Printing, formal sharing | |
| JSON | Project data | Reopening and continued editing |
The first three are output formats — finished results. JSON is different: it stores your drawing as data you can bring back onto the canvas.
2. PNG: Images for Everyday Sharing
PNG is the workhorse. It produces a flat, universally supported image that drops into documents, presentations, messaging apps, and websites without fuss. Choose PNG when you want a picture of your drawing that anyone can open, and when scaling to enormous sizes is not a concern.
Because PNG is raster (made of pixels), it looks best at the size it was exported. If you expect to enlarge it later — a wall print, a projected slide — export at the largest canvas size you can first, since scaling a small PNG up introduces soft, blocky edges. For work that must scale crisply to any size without that penalty, SVG is the better choice.
3. SVG: Scalable Vectors for Design
SVG stores your drawing as vector paths rather than pixels, so it stays razor-sharp at any zoom level — a 2 cm diagram and a 2 m banner come from the same file with no quality loss. Open an SVG in a vector editor such as Inkscape (free), Adobe Illustrator, or Affinity Designer, and every line remains an editable object you can recolor, restyle, or reshape.
SVG is the right pick when the drawing will be scaled, incorporated into a design workflow, or edited in professional graphics tools. One caveat: a drawing with thousands of individual strokes produces a large SVG that some apps render slowly — for very dense raster-like work, PNG can be the lighter file. If you specifically need a true-scale vector graph-paper sheet, the A4 graph paper tool also exports pure vector SVG and PDF.
Create something to export
Open the drawing canvas →4. PDF: Documents and Printing
PDF wraps your drawing in a page you can print or share as a formal document. It is the natural choice when you are handing work to someone who expects a document rather than an image file, or when you want a printable copy. For printing blank grid sheets rather than a drawing, use the printable graph paper generator instead.
5. JSON: Keeping Your Work Editable
JSON is the format people overlook and later wish they had used. It saves your drawing as structured project data — every object, position, and setting — so you can load it back onto the canvas and keep editing exactly where you left off.
Think of PNG, SVG, and PDF as snapshots, and JSON as the editable source. A good habit is to export both: a PNG or PDF to share now, and a JSON to preserve the editable version. This pairs well with the canvas’s automatic in-browser save — read saving and recovering your drawing for how local auto-save and JSON export complement each other.
6. Choosing the Right Format
- Sending to a friend or teacher? PNG or PDF.
- Putting it in a slide deck? PNG.
- Editing in design software or scaling large? SVG.
- Printing a document? PDF.
- Coming back to edit later? JSON (plus a snapshot format).
Common Mistakes
- Exporting only a PNG and losing the ability to edit — export a JSON too.
- Using PNG for large-format printing, where SVG scales better.
- Assuming auto-save is a backup — it lives in one browser; exported files are portable.

Conclusion
Exporting is where a grid drawing becomes useful beyond the canvas. PNG shares it, SVG scales it, PDF documents it, and JSON keeps it alive for future edits. Match the format to the destination — and when in doubt, export a snapshot to share and a JSON to preserve. Every export happens in your browser, so your work stays on your device.
Frequently Asked Questions
Which export formats does the drawing canvas support?
The canvas exports four formats: PNG (a flat image), SVG (a scalable vector file), PDF (a document page), and JSON (a project file you can reopen on the canvas to keep editing).
Which format should I choose?
Use PNG for notes, slides, and messaging; SVG for design software and infinite scaling; PDF for printing or sharing a document; and JSON when you want to reopen the drawing later and continue editing it.
Can I reopen an exported drawing to edit it?
Yes. Export as JSON, then load that file back into the canvas. JSON preserves your objects as editable data, unlike PNG, SVG, or PDF, which are finished output formats.
Does exporting upload my drawing anywhere?
No. Exports are generated in your browser and downloaded to your device. Your drawing is not sent to a server as part of exporting.
