Frequently asked questions
Is there a file size limit?
Each file can be up to 50MB. There is no limit on the number of files you can merge.
Will the merged PDF keep bookmarks and links?
Yes — internal links and bookmarks from each source PDF are preserved in the output.
Are my files stored anywhere?
No. Processing happens on our server only for the duration of the request and files are never saved to disk.
