よくある質問

Quick answers.

Does splitting a file reduce its quality?

No. This is a lossless binary split that preserves every byte of the original data. Rejoining the chunks will produce an identical copy of the source file.

How do I rejoin the split files?

Switch to the Joiner tab, select all the chunk files at once, and ensure they are in the correct numerical order before clicking Join. The browser will then prompt you to save the reconstructed file.

Is there a limit on file size?

The maximum size depends on your browser's available memory. For extremely large files (several gigabytes), ensure you have enough free RAM and disk space for the output.

Are my files uploaded to your server?

No. The splitting and joining processes are executed entirely within your browser's local environment. Your files stay on your machine Throughout the entire process.
