Quick Summary: Merge PDF
Merge multiple PDF files or images into a single PDF document. Simply upload your files and arrange them in the order you want. Siliph's Merge PDF is a free in-browser PDF utility featuring a built-in AI assistant to optimize formatting, suggest settings, and answer compliance questions.
What does Merge PDF do?
Merge PDF combines multiple PDFs and images into one document in the order you choose. Drag to reorder, then download a single combined file.
When to use Merge PDF
- Combining invoices, contracts, or ID scans into one submission packet
- Building a portfolio or application bundle in a specific page order
- Mixing PDF pages with JPG/PNG scans from your phone
- Preparing a single file for e-signature or printing
Job applications, loan packets, and legal bundles often require one consolidated PDF instead of scattered attachments. Merge saves time and prevents reviewers from opening files in the wrong order.
Images (JPG, PNG) are converted to pages automatically, so you can mix phone scans with native PDFs. The merged output follows your thumbnail list exactly.
No watermarks on the free tier. Processing is encrypted and files are removed from servers shortly after completion.
Siliph merge and page-organize tools reorder and combine documents in the browser, using encrypted uploads so multi-file packets stay private. Output is purged within two hours on the free tier, and you can build ordered PDFs with no account required.
