Converting a PNG to SVG — also called "raster to vector" or "vectorisation" — transforms a pixel-based image into a resolution-independent vector graphic. The result can be scaled to any size without any quality loss. This is particularly useful for logos, icons, and line art that need to look sharp at both thumbnail sizes and billboard scale.
When to Convert PNG to SVG
PNG to SVG conversion works best for images with simple, distinct shapes and colours — logos, icons, line drawings, and text graphics. It doesn't work well for photographs or images with complex colour gradients, as the vectorisation process approximates shapes and creates simplified colour regions. For such images, keep the PNG and focus on compression instead.
| Best for PNG → SVG | Not suitable |
|---|---|
| Logos and wordmarks | Photographs |
| Simple icons | Complex gradients |
| Line art / diagrams | Realistic illustrations |
| QR codes | Watercolour / textured images |
How to Convert PNG to SVG Online
- Open the Image Converter at imgresizr.com.
- Upload a clean, high-contrast PNG — ideally with a transparent or plain background.
- Select SVG as the output format.
- Download your SVG file and open it in a browser or vector editor to verify the result.
Tips for Better PNG to SVG Results
Start With a Clean PNG
The better the input PNG, the better the SVG output. Use a high-resolution, high-contrast source image with clean edges. Anti-aliasing and compression artefacts in the PNG will be traced as part of the vector, creating jagged or rough edges. Remove the background from the PNG before converting whenever possible.
Simplify the Colours
Vectorisation algorithms work by grouping similar-coloured regions. Fewer distinct colours in your PNG leads to a cleaner, simpler SVG with smaller file size. For logos and icons, this usually means the SVG closely matches the original design with small, manageable file sizes.
