How to Use：

1. **Format Conversion**: Select video/audio conversion, import the file, set the output format (MP4/MP3, etc.), and customize the resolution/bitrate. Start the process.

2. **Video Compression**: Select the compression function, import the video, and automatically compress it to high definition or manually adjust parameters to quickly reduce file size.

3. **Batch Processing**: Add multiple files in batches, set parameters uniformly, and start batch conversion/compression with one click.

4. **Storage Settings**: Defaults to saving to the media library; you can customize the save path (e.g., SD card) in the settings.

5. **Tips**: When adjusting resolution, check "Maintain Aspect Ratio" and "Prioritize Quality"; when compressing large files, reserve 1.5 times the storage space; supports pause and resume download; select MP4/MP3 format for cross-device use.

FAQs

### 1. Will selecting "Custom Resolution" when converting a video cause blurring? Can I manually adjust the image quality parameters?

As long as the resolution is set appropriately, blurring is generally not noticeable, and manual image quality optimization is supported. Forcibly stretching a low-resolution video to a higher resolution may cause the image to appear out of focus. However, when converting from a high-resolution to a low-resolution, selecting "Maintain Aspect Ratio" and enabling "Prioritize Image Quality" mode will maximize detail preservation. Additionally, some versions allow manual adjustment of the frame rate and bitrate on the "Custom Resolution" page to further balance image quality and file size.

### 2. Will compressing large videos consume a lot of phone memory? Can I pause the compression process?

Compression primarily uses temporary storage space, not permanent memory consumption, and it can be paused. Before compressing large files, it's recommended to ensure that your phone has at least 1.5 times the file size remaining. Temporary files are automatically deleted after compression is complete, leaving no remaining files. If you need to pause the compression process midway, simply tap the "Pause" button. The next time you open the app, you'll be prompted to "Continue where you left off" without having to start over.

### 3. Can I batch convert multiple audio/video files? For example, I could convert 10 FLAC audio files to MP3 at once.

Batch conversion is supported, making it highly efficient. On the "Audio Conversion" or "Video Conversion" page, select "Batch Add" to import multiple files of the same type. Then, set the output format and parameters. Click "Start Conversion" and the app will automatically process them one by one, eliminating the need to manually process them one by one. This makes it ideal for batch processing.

### 4. Where are the converted files automatically saved? Can I customize the save path?

By default, they are saved to a dedicated folder in the phone's "Media Library," but custom paths are supported. In the app's "Settings - Storage Location," you can manually choose to save to the phone's internal storage, SD card, or a specific folder for easy access later. Some versions also support "Automatically share after conversion," allowing you to directly send files to cloud storage or social media apps, reducing manual file transfer steps.

### 5. After compressing videos using this app, can I guarantee that they will play properly on my phone, tablet, and TV?

As long as you choose a universal output format, it's generally compatible with multiple devices. We recommend using MP4 and MP3 as the preferred compression format, as these two formats are universally compatible with devices like phones, tablets, TVs, and projectors. To play on a specific device, select a supported format in "Output Format" or check "Device Compatibility Recommendations" within the app.
