Privacy
Merge PDF processes files on FileToolsHub servers for this conversion job. You upload a file, the worker runs the action, then you download the result.
Temporary files are stored only long enough to complete processing and are removed afterward. Do not upload content you are not allowed to process.
For highly sensitive material, prefer offline software or client-side tools on FileToolsHub when a browser-only option exists for your workflow.
Limitations
- Merge PDF has practical file-size and timeout limits. Complex or corrupted files may fail — try a simpler PDF or a smaller upload.
- Merge PDF does one focused job. For multi-step workflows, use the related tools below or the PDF Tools hub.
