Choose the right output before you convert
For audio sharing
MP3 is usually the easiest choice when you need a smaller audio file for email, web upload, phones, or class materials. A bitrate around 128-192 kbps is enough for many voice recordings, while music often benefits from 192-320 kbps.
For audio editing
WAV is larger, but it is convenient for editing because many audio programs handle it without extra decoding steps. If you plan to cut, mix, or archive source audio, keep a WAV copy and export MP3 only when you are ready to share.
For images
Compress images when the visual size is already right but the file is too heavy. Resize images when the pixel dimensions are too large. PNG is useful for crisp graphics, JPG is practical for photos, and WebP is efficient for web pages.

FAQ
Are my files handled safely?
Files are processed inside your browser and are not uploaded to a server. The result is not stored on a server either.
Do M4A, FLAC, OGG, AAC, and OPUS conversion work in every browser?
They work when the browser can decode the source codec. Modern browsers usually handle common formats like M4A, FLAC, OGG, AAC, and OPUS well.
Are files uploaded to a server?
No. This MVP runs decoding, editing, and encoding inside your browser.
Can I convert large files?
Yes, but larger files can take more time. Keep the browser tab open while processing is running.
