Combine separate scans into a single PDF file

1 min read·25 July 2026

A contract scanned in multiple sessions, receipts saved one at a time, identity documents as separate files — PDFrust helps you combine all those individual scans into one organised PDF.

Merge scans step by step

Upload all separate scan PDFs to the merge tool. Drag them into the correct order (you can reorder after uploading). Click "Merge" — all scans become one PDF. Download the result.

Convert images (JPG/PNG) to PDF first

Got scans as image files rather than PDFs? Use the jpg2pdf tool to convert multiple JPG or PNG files to PDF in one step. Then merge the resulting PDFs normally.

Improve quality after merging

Scanned documents can be crooked or have inconsistent contrast. Use the rotate tool for skewed pages. Use the grayscale tool to harmonise inconsistent colours across scans. Use the compress tool to reduce the final file size.

Add OCR to the merged scan

After merging, apply OCR to make the text searchable. Upload the merged PDF to the OCR tool. The result is a searchable PDF with the original scanned layout preserved.
