Classify PDFs

Drop a messy pile of PDFs — AI labels each (invoice, contract, resume, report…) and sorts them into folders inside one ZIP, so a chaotic folder comes out neatly organized. Your files never leave your device.

Classify PDFs — FAQ

How do I use it?

Drag and drop your PDFs — or a whole folder — onto the page, or click "Choose PDFs" / "Choose folder". Press "Sort all" and the AI labels each file with a category (invoice, contract, resume, report and so on). When it finishes, click "Download sorted ZIP" to get one ZIP with your files grouped into category folders. You can sort up to 30 files at a time.

Are my files uploaded to a server?

No — your actual PDF files never leave your device. Each PDF is read right in your browser to pull out its text, and only that extracted text is sent to our AI service to decide the category. The files themselves stay local, and the final ZIP is built in your browser from your originals.

Does it work on scanned PDFs or photos of documents?

Not directly. A scanned or image-only PDF has no text layer, so there's nothing to read — those files come back marked "no text" and land in an "Uncategorized" folder. Run them through OCR first (our "OCR PDF" tool adds a text layer), then sort them here.

Do I need an internet connection?

Yes. The text is extracted on your device, but the actual classification is done by our AI service online, so you need to be connected. The text extraction and the final ZIP packaging happen locally; only the category decision needs the internet.

What do I get back, and are my original files changed?

You get a single ZIP named dockdocs-sorted.zip with one subfolder per category, and your original PDFs placed inside — untouched and unmodified. If two files would end up with the same name in the same folder, we add a "-1", "-2" suffix so nothing gets overwritten.

How accurate are the categories?

The categories are AI-suggested from each document's text, so they're a strong starting point but worth a quick check — especially for unusual documents. To keep it fast, the AI reads only the first 6 pages of each PDF, which is plenty for most files but can miss the point on a document whose type only becomes clear later on.
