Web & Browser Format Guides
Browser support is the web’s compatibility layer. These guides connect Chrome/Safari realities to Format Convertly converters so you can ship modern formats with safe escapes.
Quick take: WebP and AVIF win on size; JPG/PNG remain fallbacks. SVG powers logos. MP4/WebM cover video. Support pages and converters keep shipping unblocked.
Web & browsers guides
Best Image Format for Chrome
Chrome handles WebP and AVIF excellently. Use them for performance; keep JPG/PNG fallbacks only when you must support ancient clients.
WebP Browser Support
WebP is supported in all modern evergreen browsers. Convert to JPG/PNG only for legacy apps, email clients, and old enterprise browsers.
AVIF Browser Support
AVIF works in current Chrome, Firefox, and Safari. Provide WebP/JPG fallbacks for older clients and convert assets when editors cannot open AVIF.
SVG Browser Support
All modern browsers render SVG. Prefer SVG for logos/icons; rasterize to PNG when a channel rejects SVG (some email, CMS, or social crops).
Best Video Format for Browsers
MP4 (H.264/AAC) is the safest browser default. WebM is excellent on Chromium. Convert MKV/MOV sources to MP4 before embedding.
Images
Prefer WebP/AVIF with JPG/PNG fallbacks. Use SVG for logos and icons.
Video
MP4 (H.264) is still the universal embed; WebM is strong on Chromium.

FAQ
Do I need fallbacks for WebP still?
For very old browsers, yes. Most modern traffic is fine with WebP/AVIF plus a JPG fallback on critical heroes.
