About this app

RetroViewer is the Android app for opening the image and animation formats
time forgot.

Old DOS pictures, Amiga demos, Atari ST art and childhood CD-ROMs left behind thousands of files in formats no modern app can open. FLIC animations from Autodesk Animator. Deluxe Paint files from the Amiga. Degas and NeoChrome pictures from the Atari ST. Smacker videos from 90s games. And more...

Until now, opening them meant firing up an emulator or giving up.

RetroViewer opens them directly on your phone.

HOW IT WORKS

Open any supported file directly from your file manager, or browse a folder
you select. RetroViewer detects the real format by reading the file itself —
not by trusting the file extension, which is often wrong or missing on old
archives.

Some old formats can contain an image, an animation, or multiple pages
depending on what's actually inside — RetroViewer figures it out and shows
you the right viewer automatically.


FEATURES

- Direct playback — no emulator, no PC, no conversion needed first
- Frame-by-frame navigation for animations
- Pinch-to-zoom on images, including tiny 320×200 retro resolutions
- Tap for full screen
- Full metadata display: resolution, color depth, palette size, frame count
- Export to PNG, WEBP, GIF, MP4, or APNG (Premium)
- Works completely offline — your files never leave your device


WHO IT'S FOR

- Amiga, Atari ST and DOS retro-computing enthusiasts
- Digital preservation and archiving communities
- Collectors of old demos, game assets, and CD-ROM content
- Developers curious about legacy graphics formats
- Anyone who just found an old floppy disk backup

RetroViewer doesn't try to be everything. It does one thing: bring forgotten
image and animation formats back to life, right in your pocket.

Have a file that won't open? Formats are being added over time — feedback is
welcome.
