Frequently asked questions
About PDF Merger and how Tarumak Studio works.
How many PDFs can I merge at once?
There is no hard limit. You can merge as many files as your browser memory allows. Very large files may be slow.
Can I reorder files before merging?
Yes — drag the files into the order you want before clicking Merge. The final PDF follows that sequence.
Is the merged PDF stored anywhere?
No. All processing happens locally. The merged file is generated in your browser and downloaded directly.
Is PDF Merger really free?
Yes — completely free, with no usage limits, no watermarks and no premium wall. Every tool on Tarumak Studio is free to use.
Do I need to create an account?
No. There is no sign-up, no login and no email required. Open the tool and use it immediately.
Are my files uploaded to a server?
No. PDF Merger runs entirely in your browser — your files are processed locally and never uploaded, which also makes it faster than server-based alternatives.
What formats does it support?
PDF Merger works with PDF.
Does it work on mobile?
Yes. The tool runs in any modern browser on desktop, tablet or phone — no app install needed.
