Frequently Asked Questions

PDF Inspector vs Smallpdf: which should you choose?

Pick Smallpdf if you need a Swiss-army knife for everyday PDF tasks—converting, compressing, editing, and signing—especially if you work across web and mobile. Choose PDF Inspector if your goal is transforming complex PDFs into clean Markdown for LLM pipelines or knowledge bases, and you value privacy through local processing. Don't buy either for advanced form creation or batch-heavy workflows.

Can I use Smallpdf offline?

No, Smallpdf is web-based—you need internet. PDF Inspector also runs in-browser but processes locally, so after page load, you can work without an active connection for device files.

Does PDF Inspector support OCR for all scanned PDFs?

Yes, but its selective OCR only applies to image-based pages. For mixed documents, it routes only the pages that need OCR, preserving accuracy and speed.

Which tool handles tables better?

PDF Inspector is built for table recovery—it reconstructs tables from drawing operations and text alignment, handling bordered and borderless layouts. Smallpdf converts to Excel but may not preserve complex table structure as cleanly.

Is my data secure with these tools?

Smallpdf uses 256-bit TLS and is ISO/IEC 27001 certified, GDPR/CCPA compliant, but files upload to the cloud. PDF Inspector never uploads device files—everything stays local, which is better for sensitive documents.

Can I convert PDF to Markdown with Smallpdf?

Smallpdf doesn't list Markdown as an output format. PDF Inspector's primary output is Markdown, making it the clear choice for that need.

How do free tiers compare?

Smallpdf's free tier offers a limited number of tool uses per day (e.g., compress, convert). PDF Inspector's free tier allows basic conversions but caps file size or OCR usage—exact limits vary by plan.

Which tool supports e-signatures?

Smallpdf integrates with Sign.com for e-signatures. PDF Inspector has no signing features—it's solely for analysis and conversion.

Can I use these tools on mobile?
