Reduces image file size to a specific target — 50 KB, 100 KB, or 200 KB — by automatically adjusting JPEG quality, reducing pixel dimensions, or stripping EXIF metadata. Ideal for government forms, job applications, and upload portals with strict file size limits.
AIFF (Audio Interchange File Format) uses uncompressed lossless encoding and is best for Apple professional audio — Logic Pro, GarageBand, and macOS music production workflows. Opus (Opus Interactive Audio Codec) uses lossy compressed encoding and excels at voice-over-IP, real-time communication, and streaming at very low bitrates with excellent 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.
64-128 kbps is recommended for music. 32-64 kbps works well for speech. Higher bitrates preserve more detail but produce larger files.
Opus supports 8kHz to 48kHz. AIFF files at higher sample rates (96kHz, 192kHz) are resampled to 48kHz maximum during conversion.
All modern browsers support Opus natively in WebM containers. For standalone .opus files, most media players (VLC, foobar2000) support them.
Yes. All conversion runs in your browser using FFmpeg WASM. No audio files are uploaded.
