Private by design, not by policy.
Decoding, colour picking, tracing and export all happen in your browser's memory. Close the tab and the image is gone.

Privacy, enforced
Your images stay in the harbor.
Most converters say they delete your file after an hour. We never receive it in the first place, and you don't have to take our word for it: the browser itself blocks the converter from sending anything.

Works offline
Load the page, switch on airplane mode, convert. Same result.
No account
Nothing to sign up for, so there is no profile, password or email address to leak.
Fast anywhere
Pages load from the nearest server in a global network. Your images never go there.
No cookie banner
You didn't see one because there is nothing to consent to.
How it works
Four steps, all inside your browser tab.
The same pipeline runs on every image, in about a second for a typical logo.
- #1F3D36#F1E6CF#E07A3F
Pick the colours
k-means finds the main colours, then snaps each to an exact pixel from your image, so your brand orange stays #E07A3F.
Split into layers
Every colour becomes its own mask. Toggle, recolour or remove a layer before anything is traced.
Trace the outlines
Each mask becomes the simplest polygon that follows it, then smooth Bézier curves, with sharp corners kept sharp and as few nodes as possible.
Stack without gaps
Lower layers run under the ones above, so edges overlap instead of meeting. No white hairlines when you scale, print or cut.
Before / after
Drag the line. Zoom in on the edges.

Cricut-ready cut files
The Cut file preset outputs clean, closed shapes that Design Space and laser software accept.

Once the page has loaded, the network is optional. Pro installs it as an app.
Use cases
From a blurry PNG to something you can print, cut or ship.
Your logo, ready for print
Signage, business cards and t-shirts need a vector. Get one from the PNG you already have.
Logo to SVGCricut, Silhouette & laser
Clean closed shapes that weed well, with speck removal tuned for vinyl and wood.
SVG for CricutIcons for the web
Small, optimised SVG you can paste straight into your code. Copy it in one click.
PNG to SVGEmbroidery & vinyl
Few flat colours, one layer each, so digitising and plotting software can follow them.

FAQ
Questions, answered plainly.
Still unsure? The privacy page shows how to check every claim on this page yourself.
Is SVG Harbor really free?
Yes. The converter is free forever, with no signup and no watermark. Pro adds batch conversion, larger images, saved presets and an offline app, and removes sponsor slots. You never need it to convert an image.
Do you ever see my images?
No. We never receive your images. The conversion runs in your browser, and the page's Content Security Policy blocks the converter from making network requests. You can confirm it in your browser's Network panel.
Why is there no cookie banner?
Because we don't set cookies or load third-party scripts. Visitor numbers come from our host's aggregated dashboard, so there is no analytics script and nothing to consent to.
Which files can I convert?
PNG and JPG. Logos, icons, line art and illustrations with flat colours give the cleanest results. Photos work with the Photo poster preset, which reduces them to a handful of colours.
How does the tracing work?
SVG Harbor splits your image into its main colours, makes one mask per colour and traces each mask into the polygon with the fewest edges that still follows it. Every bend then becomes either a sharp corner or a smooth Bézier curve. It all runs in your browser tab.
Will the SVG work in Cricut Design Space?
Yes. Use the Cut file preset: it outputs closed paths, removes specks and keeps one layer per colour, which Design Space imports as separate cut layers.
