PDNob Online

Free, with no watermarks, no ads and no signup, PDNob Online is an online PDF tool that runs in your browser and handles OCR, merging, compression, signing, conversion and password protection.

Nothing needs to be installed.

The core features are available without limits, which is not something every free PDF site can say.

The OCR is powered by ABBYY and pulls editable text out of scans and images in multiple languages.

That makes PDNob Online a practical AI scanner for paper documents and photographed pages.

Batch processing lets you convert, compress, merge or OCR several files in one session instead of repeating the steps for each one.

Output quality is a stated focus: layout, fonts and images are preserved when you convert or merge.

On privacy, uploads are encrypted with SSL, stored temporarily and deleted automatically within hours.

Still, since files are uploaded to a server, think twice before sending highly sensitive documents.
