PDFs and photos in the same file
There's no need to convert your photos first. You can mix PDFs with JPG, PNG or WEBP images and everything ends up in the same document, in the order of the list.
PDF pages are copied without being compressed again, so the text stays selectable and the quality doesn't change. Each photo goes on its own page.
Private by design
Most online tools upload your files to their servers. Not here: everything is processed in your own browser and nothing is ever sent anywhere. That's why you can safely use it with your ID, passport, payslips, medical reports or contracts.

Frequently asked questions
Are my files uploaded to a server?
No. Everything is processed inside your browser. Your files never leave your device.
Is it free?
Yes. No sign-up, no watermark and no usage limits.
How many PDFs can I merge?
There's no fixed limit. It depends on your device's memory. Dozens of ordinary documents merge without trouble on any recent computer or phone.
Do PDFs lose quality when merged?
No. PDF pages are copied as they are, without being compressed again. The text stays selectable.
Can I merge a password-protected PDF?
If it needs a password to open, no: remove it first. If it only has copy or print restrictions, its pages are added as images.
The final PDF is too big. What can I do?
Run it through the PDF compressor and enter the maximum size you've been given. It shrinks the file until it fits.
