The codec to encode the video track. Codec "Without reencoding" copies the video stream from the input file into output without re-encoding if possible.
CQ ensures that every part of the video gets the number of bits needed to achieve a certain perceptual quality level regardless of scene complexity.
Set an output video resolution by selecting one from the predefined set of the most popular resolutions or manually entering a custom resolution.

gif

GIF (Graphics Interchange Format) was introduced by CompuServe on June 15, 1987 as a platform-independent image format for transmitting color graphics over the CompuServe online service's modem-speed connections. The format uses LZW (Lempel-Ziv-Welch) lossless compression on indexed-color images with a palette of up to 256 colors selected from a 24-bit RGB color space. GIF's most distinctive capability is animation: multiple image frames can be stored sequentially within a single file, each with independent delay timing, disposal methods, and local color palettes, enabling short looping animations without any video codec or player. The format also supports binary transparency (one palette entry designated as fully transparent) and interlaced display for progressive rendering. GIF became synonymous with web culture — animated GIFs proliferated across early websites, messaging platforms, and social media, evolving into a communication medium in their own right. One advantage is universal animation support — GIF animations play natively in every web browser, email client, messaging app, and social platform without plugins, codecs, or compatibility concerns, a level of ubiquity no other animation format has achieved. The lossless compression on palette-based images provides another strength: graphics with flat colors, text, and sharp edges (logos, diagrams, UI elements) compress efficiently without the artifacts that affect JPEG. Although the LZW patents that once threatened GIF's use expired in 2004, and newer formats like WebP and AVIF offer superior compression with full-color animation, GIF's cultural entrenchment keeps it irreplaceable for casual animated content.

webm

WebM is an open, royalty-free multimedia container format developed by Google and launched at the Google I/O conference in May 2010. The format pairs the Matroska container (a subset of MKV) with VP8 or VP9 video codecs and Vorbis or Opus audio codecs, creating a fully open media stack designed specifically for web use. Google released WebM alongside the VP8 codec under permissive BSD-style licensing, removing patent and royalty barriers that hindered the adoption of H.264 for open web video. The WebM container inherits the efficient binary structure of Matroska while restricting it to web-optimized profiles, ensuring fast parsing and lightweight implementation in browsers. WebM with VP9 achieves compression efficiency competitive with H.264 High Profile and approaching HEVC, making it practical for delivering high-quality video at reduced bandwidth. Major web browsers including Chrome, Firefox, Edge, and Opera support WebM playback natively, and YouTube uses VP9 in WebM as a primary delivery format for much of its content. The format supports features such as alpha channel transparency in video, making it valuable for compositing web graphics and overlays. More recently, WebM has been extended to support AV1 video, continuing its evolution as a vehicle for open codec adoption. The combination of competitive compression, zero licensing costs, and universal browser support makes WebM a cornerstone of royalty-free web multimedia delivery.

Extreme Compression

VP9 codec in WebM compresses animated content far beyond what GIF can achieve — expect 80-95% smaller files with smoother playback and no color banding.

Video Controls

Adjust codec settings, output resolution, and quality level to shape the final WebM exactly how you need it for your website or project.

Cross-Platform Playback

WebM plays in all major browsers and most media players. Convert once and share your animation across desktops, tablets, and phones.

Frequently Asked Questions

Why convert GIF to WebM?

WebM uses VP9 compression for dramatically smaller files than GIF while keeping full color depth and smooth animation at any resolution.

What plays WebM videos?

Chrome, Firefox, Edge, and Opera support WebM natively. VLC and MPV play it on desktop. Safari added WebM support in recent versions.

Does WebM support transparency?

Yes — WebM with VP9 supports alpha channel transparency, making it a genuine animated GIF replacement for web overlays and graphics.

How much smaller is WebM vs GIF?

A typical animated GIF can shrink by 80-95% when converted to WebM, thanks to VP9 video compression versus the antiquated LZW used in GIF.

Can I embed WebM on a website?

Definitely — use the HTML5 video tag to embed WebM directly. It loads faster and uses less bandwidth than an equivalent GIF animation.
