Free Image Vectorizers Compared: Inkscape vs Online
Try the free PNG to SVG toolTurn logos, drawings and photos into clean, scalable vector files.Open →You can turn a PNG into an SVG for free in several ways. They differ in quality, convenience and what happens to your image. Here’s how the main options compare.
Inkscape’s Trace Bitmap
Inkscape is a free, open-source vector editor for Windows, Mac and Linux. Its Path → Trace Bitmap feature converts images to vectors with several modes: brightness cutoff, edge detection, colour quantisation and multiple scans for colour images.
Pros: free with no limits, very configurable, works offline, and you can edit the result in the same app.
Cons: a large desktop install, and the interface has a learning curve. Getting good colour results takes some experimenting with scans and smoothing.
Best for: people who’ll edit the vector afterwards and are comfortable with design software.
Online converters that upload your image
Many websites convert images to SVG on their servers. Some use excellent AI-assisted tracing.
Pros: often very good results with no setup.
Cons: your image is uploaded and processed on someone else’s computer. Free tiers commonly add watermarks, limit downloads, reduce resolution or require an account, with the full-quality file behind a subscription.
Best for: occasional conversions of non-confidential images where the very best automatic quality matters most.
In-browser converters that don’t upload
Our PNG to SVG converter runs the VTracer engine inside your browser using WebAssembly.
Pros: free, with no watermark, limit or account. Your image never leaves your device. A live side-by-side preview with sliders for colours, smoothing and speck removal, plus modes for colour logos, black-and-white cut files and line art. Vector PDF export.
Cons: less hands-on editing than Inkscape; very complex photos still need manual cleanup.
Best for: quick, private conversions of logos, drawings and cut files.

Getting the best result from any vectorizer
- Start with the biggest, cleanest image you can find.
- Reduce colours to what the design really has.
- Remove noise before or during tracing.
- Compare at large size. Zoom in on curves and corners.
- Touch up in an editor if needed — Inkscape is free and excellent for this.
Recommendation
For quick, private conversions, start with an in-browser tool. If you need to refine the result, open the SVG in Inkscape. Reserve upload-based services for non-sensitive images when you’ve tried both and need a different style of tracing.
