|Full name||Scalable Vector Graphics (SVG) Tiny, Version 1.2|
SVG Tiny 1.2, released in December 2008, is a profile of SVG_1_1 (at the time, often referred to as SVG 1.1 Full) intended for implementation on a range of devices, including cellphones and PDAs. SVG Tiny 1.2 includes a subset of the features included in SVG 1.1, along with new features to extend the capabilities of SVG.
According to Adobe Illustrator Help -- Saving artwork: Save in SVG format, SVG Tiny does not support gradients, transparency, clipping, masks, symbols, patterns, underline text, strike through text, vertical text, or SVG filter effects.
SVG Tiny 1.2 may include animation via internal markup closely related to the Synchronized Multimedia Integration Language (SMIL) 2.1 Specification. The supported animation features incorporated and extended the general-purpose XML animation capabilities described in SMIL 2.1. See 16.2.2 Relationship to SMIL 2.1 Animation.
Examples of features introduced in SVG Tiny 1.2 are listed below, annotated as to whether or how the functionality was expected to be integrated into future versions of SVG based on SVG2 Requirements Input: Features from SVG Tiny 1.2.
SVG Tiny 1.2 can be validated using a normative RelaxNG schema. This is in contrast to SVG 1.1, for which an XML DTD was provided.
See SVG_family for more detail on the structure of SVG files.

|Subtype of||SVG_family, Scalable Vector Graphics (SVG) File Format Family|
|Subtype of||XML, XML (EXtensible Markup Language)|
|Modification of||SVG_1_1, Scalable Vector Graphics (SVG), Version 1.1|
|Has earlier version||
SVG Tiny 1.1, not described separately on this Web site. SVG Tiny 1.2 is a backwards compatible upgrade to SVG Tiny 1.1.
|Has later version||SVG_2, Scalable Vector Graphics (SVG), Version 2.. This update is under development. As of April 2020, a W3C Candidate Recommendation, issued October 4, 2018, is available at http://www.w3.org/TR/SVG2/. The most recent editor's draft can be found at https://svgwg.org/svg2-draft/.|
|LC experience or existing holdings||None|
|Disclosure||Open standard from W3C.|
|Documentation||Scalable Vector Graphics (SVG) Tiny 1.2 Specification, published as a W3C Recommendation on 22 December 2008. SVG document instances must conform to the RelaxNG Schema for SVG Tiny 1.2 in Appendix N.|
See SVG_family for information on adoption of SVG in general.
In 2013, Ben Frain reported, "Furthermore, whilst ‘Tiny 1.2′ is widely supported on mobile devices (including iOS) good ol’ Microsoft don’t support it. Even IE10 on Surface does NOT support SVG Tiny 1.2 profile."
According to the Editor's Draft of the SVG 2 specification as of March 2020, the SVG Working Group considers version Tiny 1.2 to be a deprecated branch of the SVG standard.
|Licensing and patents||No special issues. As of October 2015, the SVG Working Group was not aware of any royalty-bearing patents they believe to be essential to SVG. See SVG Working Group Patent Policy Status|
|Transparency||Based on XML, hence inherently transparent.|
|Self-documentation||Includes <metadata> element designed to hold elements from other XML namespaces. Hence an SVG file can contain rich descriptive or administrative metadata using any other DTD or schema.|
|Technical protection considerations||No issues.|
Good support. See SVG_family
|Clarity (high image resolution)||
|Color maintenance||For SVG Tiny 1.2, colors are specified in the sRGB color space. ICC Profiles do not appear to be supported in this profile of SVG.|
|Support for vector graphics, including graphic effects and typography||Rich support for capabilities found in "draw" and "paint" programs.|
|Specification recommends that gzip-compressed SVG files have the extension ".svgz" (all lowercase) on all platforms.|
|Internet Media Type||image/svg+xml
||Included in specification as https://www.w3.org/TR/SVGMobile12/single-page.html#mimereg-mime-registration and listed at IANA. See|
|Mac OS file type||svg
||Specification recommends that SVG files stored on Macintosh file systems be given a file type of "svg " (all lowercase, with a space character as the fourth letter).|

Motivation for publication of SVG Tiny 1.2:
From Introduction in specification: "Industry demand, overwhelming support in the SVG working group and requests from the SVG developer community established the need for some form of SVG suited to displaying vector graphics on small devices. Moreover, the mission statement of SVG 1.0 specifically addressed small devices as a target area for vector graphics display. In order to meet these demands the SVG Working Group created a profile specification that was suitable for use on mobile devices as well as on desktops. The Mobile SVG Profiles specification [SVGM11] (also known as SVG Mobile 1.1) addressed that requirement and defined two profiles to deal with the variety of mobile devices having different characteristics in terms of CPU speed, memory size, and color support. The SVG Mobile 1.1 specification defined SVG Tiny (SVGT) 1.1, suitable for highly restricted mobile devices; it also defined a second profile, SVG Basic (SVGB) 1.1, targeted for higher level mobile devices. The major difference between SVG Tiny 1.1 and SVG Basic 1.1 was the absence of scripting and styling in SVG 1.1 Tiny, and thus any requirement to maintain a Document Object Model (DOM). This saved a substantial amount of memory in most implementations.
SVG Tiny 1.2 added features requested by SVG authors, implementers and users of SVG Tiny 1.1, not described separately on this website. SVG Tiny 1.2 is a backwards compatible upgrade to SVG Tiny 1.1. SVG Tiny 1.1 content was expected to render the same in conformant SVG Tiny 1.2 user agents as it did in conformant SVG Tiny 1.1 user agents.
Plans for future development: The specification for SVG Tiny 1.2 says, "this specification represents the core for a set of modular extensions, but is named SVG Tiny for historical reasons, as a profile for mobile devices. Future versions of this specification will maintain backwards compatibility with previous versions of the language, in a continuing line of technology, but will bear the name 'SVG Core' to represent this relationship." However, the plan to use the term 'SVG Core' was not implemented. According to the editor's draft for SVG 2.0 on February 16, 2020, "An intermediate version of SVG - named Tiny 1.2 - was released in 2008. However it did not receive wide acceptance and there have been very few implementations of its enhanced feature set. However there are some 1.2 features that have been implemented by many SVG implementations and those have been incorporated as part of this specification. But otherwise, the SVG Working Group consider version Tiny 1.2 to be a deprecated branch of the SVG standard."
