FORMAT COMPARISON
SVG vs PNG: which should you use?
The web’s most common format decision has a clean answer: SVG for graphics, PNG for pixels. Here’s the full comparison – scaling, size, transparency, compatibility – and the edge cases where the rule bends.
The one-question test
Could a designer redraw it with shapes and curves? SVG. Is it made of photographic pixels? PNG. That single question resolves 95% of cases.
Both directions, free
Trace PNGs into vectors with PNG to SVG, or render SVGs to pixels with SVG to PNG – both in your browser.
Performance angle
A logo as SVG is often 10× smaller than its PNG and stays sharp on every display density – free Core Web Vitals points.
Why SVG wins for graphics
A PNG logo is a snapshot at one resolution: enlarge it and the browser interpolates pixels into blur; ship it at retina density and the file quadruples. The same logo as SVG is a set of drawing instructions – every screen renders it fresh at native sharpness, the file is usually a few kilobytes, and you can recolor it with one attribute or a line of CSS.
SVG’s text nature brings quieter wins too: it gzips beautifully, versions cleanly in git, can be styled by your design system (currentColor), and its text content is machine-readable. For interfaces, the only real reason to use PNG for a graphic is a platform that refuses SVG.
Why PNG wins for pixels – and gatekeeping
Photographs are inherently pixels – a vector “version” of a photo is a stylized poster, not a copy (try it: image to SVG). Screenshots, scans, and digital paintings are the same story. PNG stores them losslessly with full transparency.
PNG also passes every upload gate on the internet, while SVG – being scriptable XML – is blocked by WordPress, most email clients, e-commerce platforms, and forums. When the destination says no to SVG, exporting a 2× PNG is the answer, not a workaround.
SVG vs PNG at a glance
| SVG | PNG | |
|---|---|---|
| Type | Vector (mathematical shapes) | Raster (pixel grid) |
| Scaling | Infinite, always sharp | Blurs/pixelates when enlarged |
| Best for | Logos, icons, illustrations, charts | Photos, screenshots, complex art |
| File size (graphics) | Usually tiny (1–20 KB) | Grows with dimensions |
| Transparency | Yes | Yes (full alpha) |
| Editability | Recolor/restyle with code or editor | Pixels only – repaint to change |
| Animation | Yes (CSS/SMIL) | No |
| Upload acceptance | Often blocked (security) | Accepted everywhere |
| Browser support | All modern browsers | Universal |
VERDICT
Use SVG for anything drawn – logos, icons, UI graphics, illustrations. Use PNG for anything photographed or screenshotted, and as the fallback when a platform refuses SVG uploads.

FAQ
Frequently asked questions
Is SVG better than PNG?
For drawn graphics – logos, icons, illustrations – almost always: infinite scaling, smaller files, editability. For photos and screenshots, PNG (or JPG/WebP) is correct; vectors can’t represent photographic detail efficiently.
Why do websites still use PNG logos?
Legacy habits and platform restrictions, mostly. Modern sites serve logos as SVG; PNG logos persist where CMSs block SVG uploads or teams lack the vector source – recoverable via tracing.
Which is better for SEO?
Indirectly SVG: smaller files improve page speed metrics, and sharp rendering improves UX signals. Both formats need proper alt text either way.
PNG or SVG for Cricut?
SVG, decisively – Cricut cuts vector paths. PNG requires Design Space to trace it first, with worse results. Details: SVG vs PNG for Cricut.
Can I convert between them losslessly?
SVG → PNG: yes, at any chosen resolution. PNG → SVG: it’s tracing, which is faithful for flat graphics and stylized for photos.
