Image Format Comparison

SVG vs JPG: Vector vs Raster Images

SVG and JPG solve completely different problems. SVG (Scalable Vector Graphics) stores images as mathematical descriptions of shapes — paths, lines, curves, and fills. JPG stores images as a grid of pixels with lossy compression. That fundamental difference determines everything: scalability, file size, editability, and which content each format can represent at all.

Quick Verdict

Use SVG when…

Use SVG for logos, icons, illustrations, diagrams, and any graphic that must look sharp at any size — from a 16px favicon to a 4K billboard. SVG also stays editable and compresses well for simple graphics.

Use JPG when…

Use JPG for photographs, product images, and any complex scene with millions of colours. SVG cannot represent photographic content — it is fundamentally a vector format for geometric shapes.

SVG vs JPG: Feature Comparison

Feature	SVG	JPG
Scalability	Infinite — crisp at any resolution	Fixed pixels — blurs when scaled up
Best for	Logos, icons, illustrations, diagrams	Photographs, product images, complex scenes
File size (logos)	Small — typically 2–50 KB	Larger — JPEG compression still applies
File size (photos)	Not suitable — huge or impossible to encode	Small — excellent for complex imagery
Editability	Fully editable XML — open in any code editor	Binary format — needs image editor
Browser support	Universal since 2011	Universal — decades of support

Frequently asked questions

Can I convert a JPG photo to SVG?

You can, but the result is not a true vector SVG — it's a raster image embedded inside an SVG container, which gives you the SVG file format without any of the benefits. True vector conversion (tracing) works only on simple graphics with flat colours. Tools like Inkscape can auto-trace simple logos from JPG with reasonable results, but photographs cannot be meaningfully vectorised.

Which is better for a website logo — SVG or PNG?

SVG is usually better for logos. SVG logos are smaller files for simple graphics, scale perfectly on retina displays, and can be styled with CSS. PNG logos work fine but need separate sizes for different densities and don't benefit from CSS customisation. Use PNG only if your logo is too complex for SVG (e.g., contains photographic textures).

Can SVG be used for Open Graph or social media images?

No. Social media platforms (Facebook, Twitter, LinkedIn) require raster images — JPG or PNG — for Open Graph images and profile pictures. SVG is not supported for these use cases. Convert your SVG to PNG or JPG first.
