Free invoice OCR tool
Free Invoice OCR Tool: Extract PDF Invoices to CSV
Upload up to 5 PDF, JPG, or PNG invoices. Extract supplier details, line items, tax, and totals into one CSV. No account required.
New batch
Add your invoices
5 files per batch
We check first
We identify each file before extracting. Invoices get the full treatment; anything else gets told what it is.
One bad scan won't stop the rest
Once a batch is accepted, every file is read separately. A blurry scan won't hold up your other four.
Come back later
Results wait for you. You get a link back to them when your files are accepted.
What happens to your files
Deleted after 48 hours
Your files and results are removed automatically — that window exists so you can come back to them, not so we can keep them.
Never used for training
Your documents don't train any model, ours or anyone else's.
No account required
We use one random browser ID to apply the daily limit. Your job ID is not sent to analytics or used for advertising.
Encrypted in transit
Files travel over TLS and are stored encrypted until they expire.
Where your files go
Files are stored in Germany (Oracle Cloud, Frankfurt) and processed on our own servers in the EU (Contabo). Everything is deleted after 48 hours. Read the privacy policy

This page is for invoice OCR and invoice-to-CSV work. It helps AP teams turn supplier files into structured rows for review. It does not pretend to replace invoice approval workflow, exception routing, or payment controls around the invoice.

FAQ
Invoice extractor questions
What is invoice OCR?
Invoice OCR reads an invoice file and turns visible fields into structured data. This tool extracts supplier details, invoice number, dates, currency, line items, subtotal, tax, and total from PDF, JPG, and PNG invoices.
What is an invoice parser?
An invoice parser turns invoice text and table structure into named fields. This PDF invoice parser returns supplier details, invoice identifiers, dates, currency, totals, and line-item rows that you can review before downloading to CSV.
Can I convert a PDF invoice to CSV?
Yes. Upload a PDF invoice, run the extractor, then download one CSV containing the extracted invoice fields and line items. The CSV output is meant for review, spreadsheet cleanup, and the next step in an AP workflow.
Does the tool extract invoice line items?
Yes. When line items are visible, the extractor returns item description, quantity, unit price, and line total where available.
Is invoice OCR the same as invoice processing automation?
No. Invoice OCR is the intake step. Invoice processing automation also covers validation rules, exception routing, invoice approval workflow checks, evidence capture, and audit trails before posting or payment release.
Do I need to create an account?
No. You can upload invoices and download the CSV without creating an account or entering payment details.
