Frequently Asked Questions

Yes, GOM Player is freeware for personal and educational use. The core media player functionality is completely free and does not require a license or subscription.

GOM Player may include optional bundled software or offer premium features through separate licensing, but the basic media player is free to download and use without any cost or time limitations.

GOM Player is licensed for personal and educational use. For commercial use, business licenses, or enterprise deployments, you should review the software's End User License Agreement (EULA) or contact the software publisher for appropriate licensing terms.

Commercial usage may require a separate license agreement depending on the specific use case and jurisdiction.

During installation, GOM Player may offer optional bundled software or additional components. These are optional and can be declined during the installation process.

The core media player application itself is ad-free. However, always review installation options carefully and decline any optional software you do not wish to install. The installer will clearly indicate which components are required vs. optional.

GOM Player supports multiple methods for loading subtitles:

• Automatic: Place subtitle files (.srt, .ass, etc.) in the same folder with the same filename as your video
• Manual: Right-click → Subtitle → Open Subtitle File, then browse for your subtitle file
• Drag & Drop: Drag subtitle files directly onto the GOM Player window
• Menu: Use the Subtitle menu in the menu bar

For detailed instructions, see our Subtitle Guide.

GOM Player provides easy subtitle synchronization tools:

• Keyboard Shortcuts: Press Z/X to delay subtitles by 0.5 seconds, or C/V to advance them
• Sync Tool: Right-click → Subtitle → Subtitle Synchronization for precise millisecond adjustments
• Multiple Adjustments: Hold keys or press repeatedly for larger timing changes

Subtitles that are consistently off by the same amount can be permanently adjusted. See our Subtitle Guide for detailed instructions.

GOM Player supports a wide range of subtitle formats:

• Text Formats: SRT (SubRip), ASS (Advanced SubStation Alpha), SSA (SubStation Alpha), SUB (MicroDVD), VTT (WebVTT)
• Embedded Subtitles: MKV embedded tracks, MP4 embedded subtitles, DVD VOBSUB/IDX, Blu-ray PGS subtitles
• Styled Subtitles: Full support for ASS/SSA with fonts, colors, positioning, animations, and karaoke effects

ASS and SSA formats are particularly well-supported, making GOM Player excellent for anime and styled subtitle content.

GOM Player displays one external subtitle file at a time. However, if your video file (like MKV) has multiple embedded subtitle tracks, you can switch between them using Right-click → Audio/Subtitle → Subtitle Track. To display two subtitles simultaneously (e.g., English + translation), you would need to merge them into a single subtitle file using subtitle editing tools.

No, GOM Player includes built-in codecs for most common video and audio formats. You do not need to install separate codec packs for standard playback.

However, for some newer or less common formats (like AV1, certain HEVC variants, or specialized audio codecs), you may need to install additional codecs. GOM Player will prompt you with a Codec Finder dialog if a required codec is missing, allowing you to download it automatically.

If a video won't play, try these troubleshooting steps:

1. Check if GOM Player shows a "codec not found" error and use the Codec Finder if available
2. Try switching video decoders: Right-click → Filter → Video Decoder
3. Verify the file isn't corrupted by testing it in another media player
4. Check if the file format is supported (GOM Player supports 100+ formats)
5. Ensure you have the latest version of GOM Player
6. Check system requirements and available disk space

For detailed troubleshooting, see our Codec Troubleshooting Guide.

Yes, GOM Player fully supports 4K (3840×2160) and higher resolution playback, including 8K content. For optimal 4K playback:

• Enable hardware acceleration in Preferences → Video
• Use a modern GPU with hardware video decoding support (H.264, H.265/HEVC, VP9)
• Ensure your system meets recommended requirements (see System Requirements)
• Update your graphics drivers to the latest version

GOM Player also supports HDR10 and HDR10+ content when played on compatible displays.

Video lag or stuttering can be caused by several factors:

• Hardware acceleration: Enable GPU decoding in Preferences → Video
• High resolution: Your system may struggle with 4K on older hardware
• Video renderer: Try switching renderers (EVR, VMR9) in video settings
• Buffer settings: Increase buffer size for smoother playback
• Other applications: Close resource-intensive programs
• File source: Network streams or slow storage may cause buffering

See our Performance Optimization Guide for detailed solutions.

Yes, GOM Player is safe and legitimate software. However, you should always:

• Download from the official website or verified software repositories
• Avoid third-party download sites that may bundle unwanted software
• Review installation options carefully and decline optional bundled software
• Verify file integrity using provided checksums when available
• Keep your antivirus software updated

The core GOM Player application itself is clean, ad-free, and does not contain malware. For more information, see our Trust & Security page.

In most cases, yes, this is a false positive. Some antivirus software may flag GOM Player as potentially unwanted software (PUP) due to:

• Optional bundled components in the installer
• File association changes during installation
• Reputation-based detection algorithms

GOM Player is not malware, spyware, or adware. It is trusted by millions of users worldwide and is not classified as malicious by major antivirus vendors in their threat databases. If flagged, you can safely add it to your antivirus exclusion list, or verify the file hash from the official source.

See our Download page for more information on file integrity and antivirus false positives.

GOM Player may check for updates automatically, or you can check manually:

• Automatic: Check Preferences → General → Updates for automatic update settings
• Manual: Help menu → Check for Updates (if available)
• Manual Download: Download the latest version from the official website (Download page) and install over your existing installation

Updating typically preserves your settings and preferences. Always download updates from the official source to ensure security.

GOM Player's privacy practices depend on the specific version and publisher. Generally, the core media player application does not collect personal information or track detailed usage. However, some versions may include:

• Update checking (checks for new versions, may send basic system information)
• Error reporting (optional crash reports, typically anonymized)
• Optional analytics or usage statistics (usually opt-in)

Review the Privacy Policy during installation and in Preferences → Privacy. You can typically disable optional data collection. For detailed information, see our Trust & Security page.

GOM Player is designed specifically for Windows and is not available natively for macOS or Linux. However, you may be able to run it on Mac or Linux using virtualization software or compatibility layers like Wine, though this is not officially supported and performance may vary.

For Mac users, alternative media players like VLC Media Player, IINA, or QuickTime Player are recommended. For Linux, VLC, MPV, or MPlayer are excellent alternatives with similar features.

Yes, GOM Player is optimized for low-end systems and can run smoothly on older hardware with modest specifications:

• Minimum: Windows 7, 512MB RAM, Pentium 4 or equivalent CPU
• For best performance on low-end PCs, disable unnecessary filters, reduce subtitle quality, and use windowed mode
• Hardware acceleration helps significantly if your GPU supports it
