Submitting multiple attachments as one file
Portals often accept only one file for a submission. Merging allows you to combine the required pages into a single PDF and reduce upload mistakes.
Merge PDF
Combine multiple PDF files, or only selected pages from each file, into one document instantly. Secure and works in your browser.
How to merge PDF files When a portal only accepts one attachment, combining multiple PDFs is usually the fastest fix. This tool merges files in your browser with no installation. You can also merge only selected pages from each PDF, which is useful when you need a clean submission pack without sending entire source documents. Useful when: submitting multiple documents, building a job application packet, bundling appendices, combining scanned pages, or merging only selected pages from each PDF.
How to use
Add PDFs, optionally enter page ranges for files that should contribute only selected pages, confirm the order, merge, then verify the result before sharing it.
- Click 'Select Files' or drag and drop your PDF files
- Optionally enter page ranges for any file if you only need selected pages
- Reorder files by dragging them to your preferred order
- Click 'Merge PDFs' to combine all files
- Download your merged PDF document
Why this tool is useful
Many submissions and sharing workflows require a single PDF file. When documents are split across multiple files—scans, appendices, receipts, or separate pages—sending them individually increases the risk of missing pages or confusing order.
Merging PDFs helps you produce one coherent document that is easier to review, upload, archive, and share. In some workflows, you do not want the entire source document in the final bundle. Being able to merge only selected pages from each PDF keeps the output focused and avoids oversharing.
What this tool helps with
A single merged file reduces overhead for both the sender and the reviewer. It also makes naming and storage easier: one file per submission or case is simpler to track.
When you can control ordering, you can build a clear document flow (cover → body → appendix), which improves readability and reduces back - and - forth requests for clarification. If you can also select exact page ranges per source file, you can prepare tighter submission bundles without editing the original documents first.
Examples
Creating a readable sequence for review
Reviewers expect a logical order and consistent flow. Reordering and merging helps you avoid confusion caused by scattered documents and inconsistent naming.
Combining only the pages you actually need
Sometimes each source PDF contains extra pages you should not include. Selecting specific page ranges lets you merge only the relevant pages into one focused file.
Recommended for
Recommended if you: - need to upload one PDF instead of multiple files - combine scans, appendices, or receipts into a package - want a clear cover/body/appendix flow - need only selected pages from each source PDF - reduce page loss and ordering mistakes
