Convert and manage your game ROMs directly on Android – unleash the power of CHD!
CHDroid is your mobile-first tool for converting, extracting, repacking, verifying and managing game ROMs into the CHD (Compressed Hunks of Data) format — all directly on your Android device. It’s built for retro gamers who want to keep their library tight and portable.
Key features include:
- Batch processing of folders of files (select a folder → choose action → done)
- Background service: conversion continues while you use other apps, with persistent progress notifications
- Automatic saving: converted files are placed in the same directory as original source files
- Support for multiple operations: compress → CHD, extract CHD → BIN/CUE, repack, verify integrity, get CHD info
- Automatic detection & handling: CUE/BIN parsing, multi-disc support (generates
.m3uwhen needed) - Landscape-optimised interface (great for tablets and handhelds)
- UI customization: light/dark theme + accent colour selection
- Multi-architecture support: ARMv7, ARM64, x86, x86_64 (including Android on PC)
- No data collected and no third-party sharing (privacy-first)
For classic gamers and emulation enthusiasts:
- Free up storage by compressing large CD/DVD ROM sets into CHD format
- Keep everything mobile — no PC required
- Simplify multi-disc game management via playlist generation
- Stay portable: your entire game library travels with you
- Use offline: no constant internet connection needed
- Optimised and stable — built by a retro gamer, for retro gamers
- Install CHDroid from Google Play.
- Launch the app, grant required permissions (file access).
- Navigate to the folder containing your ROMs.
- Tap the “Select Folder” button → choose action (Compress, Extract, Verify…).
- Let CHDroid process your files in the background — you’ll get notified on progress.
- Once done, load the resulting CHD files or playlists in your emulator (eg. RetroArch, DuckStation, etc.).
Input formats: BIN/CUE, ISO, GDI/BIN/RAW
Supported actions:
- Compress → CHD
- Extract CHD → original format
- Repack CHD
- Verify CHD integrity
- Info: view CHD metadata (compression ratio, original size, etc.)
- If you have multiple discs, store them in a single folder before conversion for smooth
.m3uplaylist generation. - Use the “Pause” button if you need to temporarily stop and resume processing later.
- For large libraries, start with smaller folders to test conversion speed and accuracy.
- On Android 12+ and scoped storage environments, ensure CHDroid has access to the correct parent folder (grant permissions when prompted).
- Keep your original files until you’ve confirmed the converted CHDs work with your emulator.
CHDroid does not collect any personal data, and does not share data with third-parties. Your ROMs and conversions remain fully offline and local.
