MediaForgeDownload and convert media, right on your phone.
MediaForge saves video and audio from the sites you use, and converts your own files. Everything runs on the device: no servers, no accounts, no ads.
What it does
MediaForge shows the formats each site really offers, with their sizes, so you choose before you download. Then it saves the file where you want it.
Video in the quality you pick
From 144p to 4K, in MP4. Paste a link or share it from any app.
Audio only
MP3, M4A, Opus, OGG, WAV or FLAC, with title, artist and cover art. Copied without re-encoding when possible.
Offline converter
Change formats, trim a clip, save a frame as an image, compress a video or convert up to 50 files at once.
Subtitles and playlists
Embed subtitles in the video. Pick videos from a public playlist and download them all.
Background queue
Real progress, cancel, automatic retries and a Wi‑Fi‑only option. A searchable history of everything you saved.
Private and up to date
No analytics, no Google services. The download engine updates itself, verified by signature.
Screenshots
Real screens from version 1.0.0.
