Secure PDF to Excel Conversion Workflow

1

Local PDF Rendering

Your browser uses your device's memory to render the PDF invoice into an image locally. Your original PDF file is never uploaded to any server, completely eliminating the risk of hidden metadata or author information leaks.

2

Pixel-Level Redaction

When you draw black boxes over vendor details or sensitive addresses, the browser physically overwrites the pixels on the canvas. The original business data ceases to exist before any processing begins.

3

Pre-Flight Audit (ZIP Download)

Before any data leaves your browser, you can download the exact redacted images in an Audit ZIP file. You can physically verify that all sensitive information is completely masked and unreadable to the AI. You are in full control.

4

Stateless AI Data Extraction

Only the flattened, redacted image is securely transmitted to our EU-based API. We use a stateless architecture with zero databases and strict zero-model-training guarantees from our enterprise AI provider.

5

Client-Side Excel Generation

The raw line item data returned by the AI is assembled into a secure, structured Excel (.xlsx) spreadsheet directly inside your browser. The final download happens locally, leaving no trace of your financial data online.

How we compare to standard PDF converters

The Standard Market Approach

  • Typically, you are forced to upload your original PDF file to the provider's servers.
  • Servers save the file, including hidden author metadata and timestamps.
  • They run OCR and AI analysis on all your business and financial data.
  • Results are stored in a database to generate a downloadable link.
Risk: High risk of data leaks, usage of financial data for AI model training, and persistent files left on third-party servers.

Our Privacy by Design Approach

  • Your original PDF never leaves your machine. It is never uploaded.
  • Not a single detail of the original PDF metadata is transferred to the image files prepared for submission.
  • The AI only sees the image files you have approved - previously redacted areas are nothing more than empty, black pixels to it.
  • There is guaranteed to be no AI model training, and the final conversion result is saved exclusively on your device.
Result: Only the Excel file you requested is the final outcome - without you or your original document becoming the product.

Frequently Asked Questions

Is it safe to convert my PDF invoice, and do you upload the original file?

Your original PDF file is never uploaded to any server. Our converter uses a strict 'Privacy by Design' architecture. The document is rendered locally in your browser, ensuring your original file and its hidden metadata never leave your device.

Will my business data be used to train AI models?

Absolutely not. We process your redacted images using AI API calls, restricted strictly to EU-only infrastructure. We have contractual guarantees that your submitted data is never stored, logged, or used to train any artificial intelligence models.

How can I verify what data is actually sent to the AI?

We offer a unique "Pre-Flight Audit" feature. Before starting the AI extraction, you can download an Audit ZIP containing the exact flattened, redacted images. This lets you see precisely what the AI will see—proving your blacked-out sensitive data is physically gone.

What output format will I receive, and can it handle multi-page invoices?

The tool extracts your line items and totals, generating a clean, structured Excel (.xlsx) spreadsheet directly inside your browser. It effortlessly handles multi-page invoices, seamlessly merging all extracted line items into a single, sortable table for your accounting needs.

Do I need to create an account, and is this converter free to use?

No registration, email, or password is required. You can use the tool completely anonymously. We provide free Universal Credits every day so you can test the extraction. For larger volumes, you can purchase anonymous, pay-as-you-go Credit Packs that never expire.
