PDF Merge combines several PDF files into one downloadable document without sending your pages to a remote processor. Pick the files in the order you want them joined, run the merge, and save a single PDF that keeps every selected page.
The tool is built for everyday paperwork: contracts plus appendices, scanned chapters, signed forms, and export packs that still live as separate downloads. Everything runs in the browser with pdf-lib, so the bytes never leave your device during the merge step.
What PDF Merge does
- Accept multiple PDF uploads (up to 10 files)
- Enforce a hard 25 MB cap per file so the tab stays responsive
- Copy pages from each source document into one output PDF
- Download the combined file as
merged.pdf - Surface clear status and error messages when a file cannot be read
Who PDF Merge is for
- Office teams assembling packets before a meeting
- Students stitching lecture notes and assignment PDFs
- Freelancers combining invoices, statements, and attachments
- Anyone who prefers local processing over upload-based converters

Tips and limits
- Keep files under 25 MB each. Very large scans may need compression first.
- Encrypted or damaged PDFs can fail to load; decrypt them locally if needed.
- Browser tabs have memory limits. Extremely page-heavy packs may struggle on low-RAM devices.
- Merge order follows the order of selected files in the picker.
- This tool concatenates pages. It does not edit text layers or form fields.

FAQ
Are my PDFs uploaded to BeeForge?
No. Merge runs in your browser with pdf-lib. Files are read locally and the result downloads from a Blob URL on your machine.
How many files can I merge?
Up to 10 PDF files per run, and each file must be 25 MB or smaller.
Does merge preserve bookmarks and forms?
Page content is copied into a new document. Advanced structure such as bookmarks, annotations, or active form logic may not carry over fully.
What if one file fails?
The status and error areas explain the problem. Remove the bad file or re-export it from the original app, then try again.
Can I reorder pages after merging?
Not inside this tool. Merge again with a different selection order, or use PDF Split to extract the pages you need into a new set.
