How to merge PDF
It takes less than a minute with PDFHeron.
Add your files
Select or drop multiple PDFs and images together. They’re combined in the order you chose them.
Add more anytime
Use Merge in the editor to append more PDFs or images to the document.
Arrange the pages
Drag thumbnails in the Pages panel to reorder, and rotate or delete pages as needed.
Download
Save the merged PDF.
Quality stays intact
Pages from your PDFs are copied as-is, without re-rendering, so text stays selectable and vector graphics stay sharp. Images are added as full pages at their original resolution.
Edit while you merge
Because the merger is part of a complete editor, you can also annotate, sign, number pages or add a watermark before you save.
Why use PDFHeron to merge PDF?
Private by design
PDFHeron processes files on your device. No uploads, no cloud copies, no one else ever sees your documents.
Real editing
Change existing text and delete content from the file itself, not just paint boxes on top of it.
Instant & offline-ready
No queues or upload waits. Big documents open in seconds, and editing keeps working without a connection.
True redaction
Redacted areas are permanently removed from saved PDFs, so hidden text can’t be copied back out.
Standard PDF output
Saved files are regular PDFs with selectable text that open in Acrobat, Preview, Chrome and every other reader.
Free, or $2 once
Use every tool for free. Remove the footer forever with a one-time Pro license, with no subscription.
Merge PDF: FAQ
How many files can I merge?
There’s no fixed limit. Very large documents depend on your device’s memory, since processing happens in your browser.
Can I merge JPG and PNG images with PDFs?
Yes. Images become pages in the merged document.
Are my files uploaded?
No. Files are merged locally in your browser.
