Frequently Asked Questions

Is there a maximum file size limit? ▾

There is no hardcoded server limit since all merging leverages your device's local memory. Generally, most modern browsers handle merging documents totaling up to ~100 MB without performance degradation.

Are my sensitive documents uploaded to a server? ▾

No. Unlike traditional online PDF tools, this application processes the entire merge operation locally within your browser tab using JavaScript. Your files are never uploaded, ensuring complete data sovereignty.

Can I choose the order in which the files are merged? ▾

Yes, after uploading your initial batch of files, you can visually drag and drop the file list items to perfectly arrange their sequential order before clicking the 'Merge' button.
