About this tool
The Merge PDF tool stitches two or more PDFs into a single document. It's for anyone assembling reports, contracts, invoices, class packets, onboarding docs, application attachments or project files who'd rather not open a full PDF editor to do it.
Merging keeps related pages together and makes handoffs cleaner. Instead of firing five separate files at a client, you send one organized PDF. Instead of uploading a handful of attachments to a form, you give the portal the single document it's expecting.
It works best when your PDFs are already in the right order. Upload them, let Convertit do its thing, and download the combined file. It's a practical way to tidy up document delivery whether you're on a laptop, a phone or a shared computer.
Why Merge PDFs?
One merged PDF just reads better. A report can carry its cover page, charts, appendices and signed forms in a single file. An HR packet can bundle policies, forms and checklists. A freelancer can send a proposal, terms and invoice as one document instead of a scattered handful of attachments.
Combining files also cuts down on mistakes. When someone has to download several attachments, it's easy to skip one or read them out of order. A single PDF lays out one clear path through the material — which helps a lot when documents get reviewed, printed, approved or archived.
Preparing Files Before You Merge
Rename your files or upload them carefully so the order is obvious. Cover pages first, supporting files next, signature pages or appendices last. If one PDF has pages you don't want, split or clean it before merging so the final document stays focused.
Once it's merged, open the download and skim the first few pages, the page breaks and the final section. That quick look catches ordering slip-ups before the file lands in front of a client, school, court, employer or online portal.
Frequently asked questions
Everything you need to know about this tool.
How many PDFs can I merge?
You can merge up to 20 PDF files at once.
Can I rearrange the order of PDFs?
Yes, simply drag and drop the files to reorder them before merging.
Are my files secure?
Yes, all uploaded files are encrypted in transit and automatically deleted after 2 hours.
Will merging change the content of my PDFs?
No. The merge process combines pages into one document and does not intentionally rewrite text, images or layout inside each source PDF.
Can I merge scanned PDFs?
Yes. Scanned PDFs can be merged like normal PDFs, although very large scanned files may take longer to process.
What order will the pages appear in?
Pages appear in the same order as the uploaded files. Upload a cover page first, then supporting documents, then appendices or signature pages.
Can I merge password-protected PDFs?
Protected PDFs may fail if they cannot be opened by the processor. Remove password protection before uploading if you have permission to do so.
Can I reduce the size after merging?
Yes. If the merged document is too large, use the Compress PDF tool after merging.
Should I review the merged PDF?
Yes. Open the final PDF and check the first page, section breaks and final pages before sending or submitting it.
