Frequently Asked Questions
How do I merge PDF files online?
Upload two or more PDFs, confirm the upload order, and merge into one combined PDF. The merged file is generated in your browser workflow and then ready to download.
Does PDF merge order matter?
Yes. Pages are merged in the same order as upload, so upload files in the exact sequence you want.
Can I merge more than two PDFs?
Yes. The tool supports merging multiple PDF files in one run.
What is the file size limit for PDF merge?
Each uploaded PDF can be up to 25MB.
Will the merge process alter my pages?
The tool combines documents in order without rewriting page layout. Interactive behavior from source files can vary between PDF viewers.
Can I merge scanned PDFs and normal PDFs together?
Yes. You can combine scanned documents, exported reports, and regular PDFs into one final file.
What if merge fails or gets stuck?
Retry with fewer files per batch or smaller source files, then merge batches together. Very large scans can increase processing time.
Are my files stored after merging?
No. Files are processed temporarily to generate your output, then deleted automatically. Tiny File Tools does not require signup for these tools.
Can I use this PDF merger without creating an account?
Yes. This free PDF merge tool works without signup.
