The following tables compare SVG compatibility and support for a number of layout engines. Please see the individual products' articles for further information. Unless otherwise specified in footnotes, comparisons are based on the stable versions without any add-ons, extensions or external programs.

Explanation of the tables

Engine nomenclature

Rather than the names of web browsers, the names of the underlying engines are used. The browsers that use the various engines are listed below.

Layout engine	Release version	Preview version	Used by
Amaya	11.4.7^[1]	N/A	No longer developed; Amaya
Blink	537.36	source code^{[note 1]}	Chromium/Chrome (28+), Opera (15+), Yandex and Liebao.
Gecko	37.0.2 (April 20, 2015 (2015-04-20)^[2]) [±] ESR 31.6.0 (March 31, 2015 (2015-03-31)^[3]) [±]	Beta 38.0 Beta 9 (April 30, 2015 (2015-04-30)^[4]^[5]) [±] Developer Edition 39.0a2 (April 3, 2015 (2015-04-03)^[6]) [±] daily release Nightly 40.0a1 (March 30, 2015 (2015-03-30)^[7]) [±] daily release	All Mozilla software, including Firefox; SeaMonkey and Galeon; Camino; K-Meleon; Flock (up to 2.x); Debian IceWeasel; GNU IceCat (formerly GNU IceWeasel); Cyberfox; Icedove, Iceape and Iceowl; Fennec.

Values

Values indicate the level of support in the most recent version of the layout engine, or (if a version number is given) in the specified version. Version numbers without any other value indicate the version at which the layout engine first fully supported the feature.

Value	Meaning
Yes	Indicates that the layout engine fully supports this property/element when valid values are used.
No	Indicates that the property/element is completely ignored.
Partial	Indicates that the property/element is understood, but that not all values are supported. Supported values are implemented correctly.
Incorrect	Indicates that the property/element is understood, but that it is not implemented correctly in all cases.
Experimental	Indicates that the property/element is understood, but supported under an alternate name. May be incomplete or buggy.
Dropped	Indicates that the property/element is no longer supported.
Nightly build	Indicates that the property/element is supported to some extent in an experimental/nightly build. Future support is expected.
Depends	Indicates that the property/element is supported only on certain platforms, or if certain settings are configured.

Notes

↑ KHTML does not have any native image support. This is by design: in Konqueror, multimedia files are handled by KParts. The KDE project also developed an SVG plugin for Konqueror, known as KSVG.^{[o 1]}
↑ <embed> — Presto does not scale the image properly if its size is given in relative units.
↑ <embed>, <object> — KSVG does not scale the image properly if its size is given in relative units.
↑ list-style-image — WebKit does render the image if its size is given in relative units.^{[w 1]}
↑ Renesis 0.7 supports that feature, but because of the rewrite of the plugin Renesis 1.0 doesn't support this any longer.^{[o 2]}
