Comparison of browser engines (graphics support)

From EverybodyWiki Bios & Wiki

This article compares graphics support for several browser engines.

Explanation of the tables[edit]

Engine Status Embedded in
WebKit Active Safari browser, plus all browsers hosted on the iOS App Store
Blink Active Google Chrome and all other Chromium-based browsers like Opera and Microsoft Edge

KHTML Discontinued Konqueror browser
Presto Discontinued formerly in the Opera browser
EdgeHTML Discontinued formerly in the Microsoft Edge browser
Trident Discontinued Internet Explorer browser and Microsoft Outlook email client


These indicate the level of support for the given item in each engine. By default, the most recent version of the engine is implied. However, a specific version number can be listed; when this indicates full support, it's the initial version of the engine fully supporting the item.

Value Meaning
Yes Fully supported
No Has never been supported
Partial Only some values are supported
Incorrect Not implemented correctly in all cases
Experimental May be incomplete or buggy
Nightly build Currently in development; full support is expected
Depends Only supported for the specified conditions
Dropped No longer supported

See also[edit]


  1. 1.0 1.1 1.2 1.3 KHTML did not have any native image support. This was by design: in Konqueror, multimedia files were handled by KParts.
  2. JPEG 2000 support was only available on the macOS platform prior to the release of 10.15 Catalina, and required QuickTime 7, since Safari 12 dropped official support for NPAPI plugins (including QuickTime).[2] (Note that the referenced link leads to the Mozilla Bugzilla, where this was brought up and confirmed.)
  3. MSHTML only displayed progressive JPEGs after they were completely downloaded.
  4. There are 15 combinations of the color modes in PNG but not all modes are available in every image editor.
  5. Webkit incorrectly applies gamma correction to unlabeled PNGs.[14]
  6. Presto supported gamma correction for all color profiles except for ICC-profile.[16]
  7. In MSHTML, interlaced PNGs were displayed progressively, but in 1D instead of 2D.
