How to Merge PDF Files Online
Toolstik · Sat Sep 19 · 1 min read
Merging PDFs is a common task: combining invoices, appendices, scanned pages, or report sections into a single document for sharing or printing.
## Steps to merge PDFs
1. Open the Merge PDF tool. 2. Drop two or more PDF files (up to 50 MB each). 3. Reorder files using the up/down controls if needed. 4. Click **Merge PDFs** and download the combined file.
## Tips for best results
- Merge in logical order before compressing — compress once at the end if you also need a smaller file. - If pages are rotated incorrectly, fix rotation in a dedicated tool before merging (coming soon in Toolstik's PDF cluster). - Password-protected PDFs may fail to merge; remove protection first if you own the files.
## Privacy
PDFs are processed locally in your browser. Nothing is uploaded to Toolstik servers, making this suitable for contracts and confidential documents.
After merging, try JPG to PDF or [PDF to JPG](/tools/pdf-to-jpg) for format conversions in the same workflow.
