Convert Opus voice files to M4A for Apple Podcasts and iTunes compatibility. Publish voice content where Opus won't play — local FFmpeg work, unlimited saves.
AVIF (AV1 Image File Format) uses lossy or lossless encoding and is best for next-gen web images — royalty-free format with better compression than WebP and JPEG. JPEG (Joint Photographic Experts Group) uses lossy compressed encoding and excels at photographs, web images, and social media where smaller file size matters more than perfect quality. Converting between them lets you take advantage of each format's strengths — for example, using a compressed format for sharing and a lossless format for editing. All conversion happens locally in your browser with no file size limits.
Compatibility — JPG opens absolutely everywhere AVIF still doesn't.
High 80s–90s for photos worth keeping; lower for thumbnails and previews.
No — JPG has no alpha channel, so transparent areas flatten.
No — conversion runs locally in your browser; unlimited saves on local tools.
JPG to AVIF
Convert JPG images to AVIF format in Chromium browsers (Chrome/Edge encode AVIF via Canvas; Firefox/Safari refuse with guidance — use WebP there). Photos never leave your device — processing runs locally.
Bulk Image Format Converter
Convert image batches between JPG, PNG, WebP, and AVIF outputs (JPEG/PNG/WebP/AVIF/HEIC/HEIF/GIF/BMP/ICO/SVG inputs; HEIC via heic2any, SVG rasterized at intrinsic size or 1024px fallback) with a quality slider (10–100, default 80). Pair pages (?from/?to) preset the output. Flat ZIP renamed per file — local, 5-file guest batches, 25 signed-in, 500 Pro.
Batch Image Converter
Convert a batch of images to one output — JPG, PNG, or WebP — at quality 10–100% (default 80%), capped at 4096px longest side, then download everything as a ZIP. Files that fail conversion fall back to their originals inside the same archive — local library work.
