Before you upload a PDF to an online converter

Updated

This is a thirty second decision that nobody makes, because the upload button is right there and the question does not present itself until afterwards.

Question 1

Open the PDF and try to select a line of text. What happens?

This one test separates the three fundamentally different cases, and it takes five seconds. Everything downstream depends on the answer.

What the upload is

If the file contains personal data and you upload it to a service to convert, that service is processing personal data on your behalf. That makes it a processor and you the controller.

UK GDPR Article 28 requires processing by a processor to be governed by a contract binding the processor. It sets out the subject matter and duration, nature and purpose, type of personal data, categories of data subjects, and the controller's obligations and rights.

Terms of service are not that contract

Clicking through terms on a free site is not the same as having an Article 28 contract in place, and it is generally not written to be one.

Nor does it usually answer the practical questions: where the file is stored, for how long, who can see it, and whether it is used for anything else.

The simpler answer

Do it locally. Desktop applications and command line tools do this job well, offline, on a machine you already control, and the spreadsheet you are converting into is on that machine anyway.

For an occasional single file this is not slower than uploading, and it removes the question rather than answering it.

Where a service is genuinely needed

At volume, or where recognition quality matters, a service may be the right answer. Use one your organisation already has a data processing agreement with, which is usually one it already pays for.

The test to apply is simple: if you would not email this file to a stranger, do not upload it to one. It is the same act with a friendlier interface.

Have a lot of these, or one that will not behave?

Tell us what the documents are and how many. Data extraction suppliers who handle that kind of file will contact you directly.

Next: where to reach you.

  • Free, no obligation
  • We never ask you to upload a document here
  • No marketing lists, ever

One selection test, and you know the route

What happens when you select the text, what the data looks like, and whether it is personal. Three answers.
