SVG vs PNG: Which Should You Use?
Choose between scalable SVG vectors and fixed-pixel PNG files for logos, icons, screenshots, documents and websites.
The structural difference
SVG describes shapes, text and transformations using XML; PNG stores a fixed grid of pixels with lossless compression. That makes SVG resolution-independent and PNG resolution-dependent.
| Need | SVG | PNG |
|---|---|---|
| Scale a logo | Excellent | Limited by source pixels |
| Photographic pixels | Poor fit | Possible but often large |
| Screenshot | Poor fit | Excellent |
| Transparency | Supported | Supported |
| Bitmap-only upload form | Often rejected | Usually accepted |
How to choose
- Ask whether the artwork consists of vectors or captured pixels.
- Check whether the destination accepts SVG.
- For a vector master, keep SVG and export PNG only at required dimensions.
- For screenshots, use PNG at the intended scale.
- Verify fonts, linked assets, filters and transparent edges after conversion.
Rasterizing SVG correctly
Choose output dimensions before conversion. A 256-pixel PNG will not remain sharp when enlarged to 1200 pixels. The SVG to PNG converter creates a raster copy; it does not modify the SVG master.
Common mistakes
- Using PNG as the only logo master.
- Embedding a large photograph inside SVG and expecting vector-like efficiency.
- Rasterizing before knowing the required dimensions.
- Depending on external fonts or linked images that are unavailable during conversion.
- Assuming every upload destination permits scriptable SVG content.
Frequently asked questions
Is SVG always smaller than PNG?
No. Complex SVG artwork can be large, while a tiny simple PNG can be compact.
Can PNG be converted back into true vectors?
Not through ordinary format conversion. Vectorization requires tracing and interpretation.
