Frequently asked questions
Are my files uploaded anywhere?
No. Merging happens entirely in your web browser using your local device resources. The files never leave your computer, ensuring total privacy.
Is there a file size or count limit?
The practical limit depends entirely on your device memory. Very large files (hundreds of MB) may be slightly slower but typically process without issues.
Can I reorder the files before combining them?
Yes. Once you add files, you can use the up and down arrows to perfectly sequence them before merging.
