Online OCR is convenient: no install, no GPU, works on a Chromebook. It also means a document leaves your device for processing. That is fine for many files and unacceptable for others. Use this checklist to decide quickly.

Questions to ask before any upload

Am I allowed to process this file with a third party?
Work contracts, school policies, and client NDAs sometimes forbid external processing.
What is the worst case if this content leaked?
Public blog screenshots ≠ medical forms.
Can I redact first?
Black boxes on account numbers take thirty seconds and remove the worst risk.
Do I need the whole document?
Crop to the paragraph you need.
Is there an on-device alternative required?
Some environments mandate local-only tools.

If you cannot answer (1) with “yes,” stop.

What Textify Image does with files

In plain terms (see the full Privacy Policy):

Files are processed to perform the conversion you request.
Uploaded files and extracted text are not kept after the conversion completes.
There are no user accounts on the tool itself.
Advertising partners may process technical data for ads, separate from your document contents.

You should still only upload content you are permitted to process.

Practical redaction tips

Use your OS markup tools to black out sensitive fields before upload.
Prefer solid black rectangles over blur — blur can sometimes be reversed.
Watch for reflections and second pages visible under a thin sheet of paper.
Remember metadata: file names like ClientName_SSN_scan.pdf leak data even when the pixels are redacted. Rename files.

Network and device hygiene

Prefer HTTPS sites (Textify Image is served over HTTPS).
Avoid OCR tools that appear only as random short links with no policy pages.
On shared computers, note that browser downloads of results may remain in the Downloads folder — delete local copies you do not need.

Advertising, cookies, and your browsing data

Ad-supported tools may use cookies or similar technologies for ads and measurement. That is different from “the OCR vendor trains on my PDF,” but it is still data collection about your browser session. Use the cookie banner choices, review the privacy policy, and adjust Google ad settings if you use Google services across the web.

Special categories of data

Be extra cautious with:

Government IDs
Health information
Full financial statements
Children’s data
Credentials and API keys visible in screenshots

Often the right move is local OCR, a trusted enterprise vendor under contract, or manual transcription of the few sensitive lines.

A short yes/no flow

Situation	Suggestion
Public flyer photo	Online OCR is usually fine
Your own notes	Online OCR is usually fine
Work doc with clear policy allowing tools	Follow policy; redact if needed
Client confidential under NDA	Confirm NDA; often local-only
Medical / government ID	Default to local or specialized vendor

Convenience and privacy are a tradeoff you control at upload time. A thirty-second checklist prevents most regrets.
