Frequently Asked Questions (FAQ)
The Privacy Trade-off, Concretely
Upload-based services move your document: the file travels to their servers, gets processed there, and is deleted according to their retention policy. For a restaurant menu that is irrelevant. For an employment contract, an ID scan or a medical report it is the whole decision — you are trusting a third party's storage and staff with a copy of your document, however briefly.
Local processing removes that trust step: the file never leaves your device, so there is no upload to intercept, no server log containing your pages, and no retention policy to read. The trade is capability — server farms can run heavy OCR and e-signature workflows that a browser cannot. Match the tool to the sensitivity: convenience features for public documents, local processing for anything you would not tape to a lamppost.
Concrete Scenarios
- Converting a signed contract to images for records. Local processing — the document has personal data and a signature.
- Merging twelve brochures before a marketing launch. Either works; the upload route's automation may save clicks on files with nothing sensitive in them.
- A batch of scanned ID cards for an HR process. Local, without question.
Is WebToolsHUB's PDF to image conversion really free?
Yes — completely free with no upload limits and no registration required.
Are my PDF files uploaded to a server?
No. All processing happens locally in your browser, so your files never leave your device.
Which tool should I use for sensitive documents?
Choose a local-processing option such as WebToolsHUB for image conversion, or PDF24's desktop app in local mode for full-featured editing.
Is local processing genuinely safer, or just marketing?
It is a structural difference, not a policy promise: with no upload there is no server copy to leak, subpoena or misconfigure. Marketing would be claiming it fixes everything — heavy server-side workloads genuinely do need the cloud.
What can iLovePDF do that browser-local tools cannot?
Server-scale OCR for scanned books, legally managed e-signature workflows, and deep integrations with cloud drives. If you need those specific features, the upload trade-off may be worth it for non-sensitive files.
Are there file size limits with local processing?
Only your device memory. There is no upload cap because there is no upload — the practical ceiling is how large a PDF your browser can hold open comfortably.
