Frequently Asked Questions — Merge PDF
How many PDF files can I merge at once?
HashmiTools Merge PDF tool allows you to merge unlimited PDF files in a single session. There is no restriction on the number of files you can combine. You can merge 2 PDFs or 50 PDFs in one click. Simply add all the files you need, arrange them in order, and click Merge.
Will the merged PDF have a watermark?
No. HashmiTools adds absolutely no watermarks, logos, or branding to your merged PDF output. The resulting file is a clean, professional PDF containing only your original content. This is different from some free tools that add their branding to free outputs.
Is there a file size limit for merging PDFs?
HashmiTools handles each PDF file with no fixed size limit. For very large combined documents, the processing time may vary based on your device performance. Most business and personal PDF files are well within comfortable limits for our merger tool.
Can I reorder pages when merging PDFs?
Yes. When you upload multiple PDFs, you can drag the file cards to change the order in which they appear in the final document. For example, if you want PDF B to appear before PDF A, simply drag PDF B's card to the top position before clicking Merge.
Are my PDF files uploaded to a server when I use this tool?
No. The HashmiTools PDF Merge tool works entirely in your web browser. All processing is done locally on your device using JavaScript libraries. Your PDF files are never uploaded to any HashmiTools server, never stored in any cloud system, and never accessible to anyone else.
Can I merge password-protected PDFs?
To merge a password-protected PDF, you first need to unlock it. Once unlocked, you can add it to the merger along with your other files and combine them normally.
Does merging reduce the quality of my PDFs?
No. HashmiTools combines PDF files without any re-rendering or compression, preserving the original quality, resolution, fonts, and formatting of every page exactly as they appear in the source files.
Can I merge PDFs on my phone?
Yes. The HashmiTools Merge PDF tool is fully mobile-responsive and works on iPhone, Android, and tablets directly in the mobile browser. No app download is required and all features work with touch controls.
