Select multiple PDF files · Drag to reorder after
upload
Combine multiple PDF files into one. Upload your PDFs, arrange their order, then merge and download. Perfect for combining marksheets, offer letters, certificates, and application documents. 100% browser-based — files never leave your device.
A PDF merger combines selected documents into one PDF while preserving the order you choose. This is useful for applications, reports, study material, invoices and document packs where several separate files need to become a single submission.
Add the PDFs you want to combine, review their order, rearrange or remove files when necessary, then start the merge. Open the resulting PDF and check the page count, order and readability before sending or uploading it.
Each PDF is made of one or more pages. The merger places the pages from your files into one new PDF in the order you choose. Special features such as forms or annotations can sometimes look different in the merged file.
Name files clearly before adding them, put the first document at the top of the list, and verify the final document after export. For sensitive files, prefer browser-local processing where available and avoid uploading confidential documents to services you do not trust.
Common questions about the PDF Merger.
Merging multiple PDFs — cover letter, resume, and certificates, for example — into a single document is a common requirement for online applications that only accept one file upload. Beyond simply combining files, the order of pages and the resulting file size both matter for a clean, portal-friendly submission.
Because merging happens on your device, UTILBIT sets no file size limit — only your device's own memory. If the merged file is too large for a portal, run it through the Image Compressor or PDF Splitter first to make the individual parts smaller.
