Eluna Media
Video, audio and photo converter that runs entirely on your phone.
Eluna Media converts and compresses video, photos and audio directly on your phone. Nothing is uploaded, there is no account to create and there is no server queue to wait in — every conversion runs locally through a bundled FFmpeg engine, so your files never leave the device.
What it converts
- Video: MP4, MOV, MKV, AVI, WebM and more, with codec and bitrate under your control
- Audio: MP3, AAC, FLAC, WAV, OGG — including pulling the sound out of a video
- Photos: HEIC, JPEG, PNG, WebP, AVIF, with batch conversion
- GIFs, from a clip or from a burst of photos
What it does besides converting
- Compress to an exact file size — useful when a form refuses anything above a limit
- Trim, crop, rotate and merge clips
- Hundreds of files in one queue, processed while you do something else
You do not have to take privacy on trust
- The release build ships without the INTERNET permission on Android
- Your phone’s own app info screen will confirm the app has no network access at all
- No account, no analytics, no watermark on the result
Questions
Are my files uploaded to a server?
No. Conversion runs on the device through a bundled FFmpeg engine. On Android the release build has no INTERNET permission at all, which your phone will confirm.
Does it add a watermark?
No. The output is the file you converted, nothing added.
Can it hit an exact file size?
Yes — you set the target size and the app works out the bitrate.
Is it free?
Yes, with no subscription and no export limit.
