Questions and answers

Which files can I upload?

Each tool lists its supported formats. Files can be up to 25 MB each. Merge PDF accepts 2–10 PDFs; JPG to PDF accepts 1–10 JPG or PNG images. Other tools accept one file at a time. Input PDFs can contain no more than 500 pages in total.

Are my files uploaded to NuBox?

Files are stored only temporarily. Input files are deleted when processing finishes, and the result is deleted after the server sends your download. Undownloaded results and leftover temporary files are removed by cleanup, which runs every five minutes for files older than 30 minutes. Keep your originals.

What can change during conversion?

Layout, fonts, images and interactive features can change. Each tool explains what to check in the finished file. Keep your original and review the result before using it.
