Frequently asked questions

Is there a file size limit?
There is no fixed limit, but because processing happens in your browser, very large files depend on your device's memory.
Are my files uploaded?
No. The merge is performed locally in your browser.
Will the quality change?
No. The pages are joined without being recompressed.
Is there a limit to how many files I can merge?
Very large files or many files can be slow. Split the job into smaller groups if needed.
