Batcher is a smart local utility tool that quickly batch converts large volumes of files (such as SVG vector images and WAV audio files) directly in the browser. It operates completely in your browser without requiring complex dev environments or software installations and supports diverse convenient features for designers and developers.

No, never! This site utilizes the latest browser File System Access API along with client-side rasterization and audio decoding modules to process all file reading, conversion, and downloading 100% locally inside your web browser (Client-Side). No network transfer is performed, so you can safely use it without worrying about leaks of confidential projects or personal media assets.

Modern browsers like Google Chrome and Microsoft Edge that support the WICG File System Access API can export files directly into your original local directories, maintaining directory structure. For browsers that do not support this API (such as Safari or Firefox), files are automatically zipped in a virtual archive and offered as a single ZIP download, keeping the folder structure intact.

If left blank, the converted files will be **generated directly within the original subdirectory where each source file is located**. This preserves your directory structure, placing converted files right next to their corresponding source files.

Different configuration options are provided depending on the active tab. For **Images**, you can toggle scale options (1.0x, 1.5x, 2.0x), select the target format (PNG/JPG), and customize filename suffixes. For **Audio**, you can select the target output bitrate (e.g., 128kbps, 192kbps, 320kbps) to control encoding quality.

Once the export is successful, it will **automatically delete the original files (.svg, .wav, etc.) from your local directories**. This is convenient for organizing your files post-conversion, but since this action is permanent and irreversible, we **strongly recommend backing up important data** beforehand. (This experimental local-only feature is not supported in the ZIP download fallback mode.)

**Images (PNG/JPG)**: Choosing PNG preserves the alpha channel (transparency) of your original SVG without any loss. Choosing JPG automatically fills transparent background areas with solid white (#FFFFFF).
**Audio (WAV/MP3)**: WAV audio files are decoded in-browser and converted into standard MP3 format with your chosen bitrate.

Yes, absolutely! This tool and its internal conversion modules are built on fully open-source packages (MIT, BSD-3-Clause, SIL OFL 1.1) that have no commercial restrictions. We impose no licensing terms on your outputs. You are free to use and distribute them in any environment, including personal portfolios, commercial design kits, or paid application assets.
