Merge PDF
Merge multiple PDF files in your browser, reorder them before combining, and download one PDF without uploading documents to WebToolMint.
What this tool solves
Drag multiple PDFs into order, merge them in the browser and download one file for contracts, scans or study material.
Input: two or more local PDF files in the order you want to combine.
Output: one merged PDF containing the selected documents.
How to use it
- Choose two or more PDFs and use the up/down controls to arrange the final reading order. Touchscreen users do not need to drag files.
- Merge in the selected order and keep the tab open. Encrypted or damaged files may fail; keep the originals.
- Open the downloaded PDF and check the total pages, first/last pages, document order and orientation. Merging does not compress large scanned pages.
Common use cases
- Combine scanned documents into one file
- Join contracts, appendices or reports before sending
- Merge study notes or handouts in a chosen order
Privacy, accuracy and limits
Encrypted, damaged or very large PDFs can fail or use significant memory. Merging does not automatically optimize file size or repair source documents.
WebToolMint keeps this workflow local in the browser where the feature allows it. Network-dependent tools are labelled separately. Keep originals and independently verify results that affect legal, financial, medical or business decisions.
Frequently asked questions
Can I reorder PDFs before merging?
Yes. Put the files in the order you want before creating the combined document.
Are my PDFs uploaded?
The merge workflow is designed to run in the browser for supported files, reducing the need to send document content to a server.
Why is the merged PDF larger than expected?
Merging generally preserves the source pages. Large scans and embedded images remain large unless they are separately optimized.

Worked example and limits
Use two nonsensitive test PDFs: A has two pages and B has one. Merging A then B should produce three pages; reversing the file order should put B first. Reopen the download and check orientation, text and forms on every page. Rebuilding the document may affect digital signatures or interactive forms. Encrypted files may fail, and large documents need sufficient device memory.
