Is It Safe to Upload Bank Statements to an Online Converter?
What to look for — and what to avoid — when choosing a converter.
A bank statement contains your account number, transaction history, and counterparty details. It's one of the more sensitive documents you'll ever upload. Here's what to check before you trust any converter with yours.
Minimum bar
- TLS 1.3 in transit. A padlock in the URL bar is not enough — check the cert.
- A stated retention window. "We delete files after X hours" is a real commitment; silence is not.
- No AI training. Some tools reuse your data to train models. Look for a written policy that says they don't.
- A company behind it. A contact address, terms, and a privacy policy. Not a random GitHub link.
Nice-to-haves
- SOC 2 or ISO 27001.
- Regional data residency (EU-only processing for GDPR-heavy users).
- Encryption at rest on the server (redundant after deletion, but a good hygiene signal).
What we do
Uploads are TLS-encrypted, PDFs are processed in memory and deleted within 24 hours, and we don't retain your content beyond your download. We never feed statements to third-party training pipelines.
