Was macht PDF Merge?

Local merge protects document transfer
Use local merging for sensitive or moderately sized files. A server service may handle larger documents but requires upload and a separate retention assessment.
Wie wird es verwendet?
- Choose at least two PDF files with a combined size no greater than 100 MB.
- Arrange the file order and remove unwanted documents.
- Merge, verify the page count, and download merged.pdf.

| A PDF cannot be opened. | The file is encrypted, damaged, incomplete, or not actually a PDF. | Use an authorized unlocked and valid exported copy. |
| The tab runs out of memory. | The selected files exceed available browser memory. | Merge smaller batches on a device with more available memory. |
PDF structure can block a merge
Konkrete Grenze dieses Werkzeugs: Encryption, damaged page objects, unsupported security handlers, or insufficient device memory can stop processing. The browser does not upload the file for diagnosis.

PDF Merge — FAQ
Are PDFs uploaded?
No. Selected files are read and merged in the current browser tab.
Does merging change page quality?
Pages are copied rather than rasterized, so content is not intentionally recompressed.
Can encrypted PDFs be merged?
Not reliably. Use an authorized unlocked copy before merging.
