How to svg native filters vs. css filter property: a practical comparison
- Step 1Identify whether you need inline or external SVG — CSS filters (filter: blur(4px)) work on any HTML element. SVG filters only work on inline SVG elements by default — though SVGs referenced via img src also render their internal SVG filters.
- Step 2Assess your effect complexity — Simple effects (blur, drop shadow, brightness): CSS filter is sufficient and simpler. Complex effects (morphology, displacement maps, compositing): SVG filter primitives are required.
- Step 3Consider GPU acceleration — Both CSS filters and SVG filters trigger GPU compositing layers in modern browsers. Performance is generally comparable for simple effects.
Frequently asked questions
What can SVG filters do that CSS filters cannot?+
SVG filter primitives offer: feMorphology (erosion and dilation), feDisplacementMap (texture distortion), feTile (pattern repetition), feConvolveMatrix (custom convolution kernels), and fine-grained compositing with feComposite and feBlend.
What can CSS filters do that SVG filters cannot?+
CSS backdrop-filter applies to content behind an element (glassmorphism effect) — SVG filters cannot target content outside the SVG's own bounds. CSS filter is also simpler to write for basic effects.
Are CSS filters or SVG filters faster?+
Performance is comparable for simple effects. Both are GPU-accelerated in modern browsers. SVG filters with many chained primitives can be slower due to multiple texture passes.
Can I reference an SVG filter from CSS?+
Yes: filter: url(#my-filter) references a filter defined in an inline SVG's defs. This lets you apply complex SVG filter effects to any HTML element via CSS, combining the best of both systems.
