Is it safe to upload bank statements to online converters?
Updated 2026-10-10
A bank statement contains your name, address, account number, often a sort code or routing number, every merchant you paid and your balance. That is exactly the kind of data that is valuable to fraudsters and that privacy laws treat as sensitive.
What happens when you upload a file
Most online converters work by uploading your file to their servers, processing it there (sometimes with third-party OCR or AI services), and returning the result. Reputable services encrypt files in transit and delete them after a while — but you have to trust their policies, their subcontractors and their security. If you are an accountant, the data belongs to your client, which raises the bar further.
Questions to ask before uploading
- Where are the files stored, and for how long?
- Are files used to train models or shared with processors?
- Does the service hold a security certification relevant to you?
- Would your client be comfortable with this service having their statements?
The alternative: convert locally
LocalLedger is a web page that does the conversion inside your browser with JavaScript. The PDF is read on your device and the result is generated on your device. You can verify this yourself: open the browser's developer tools (Network tab) while converting — you will see no upload of your file. You can even disconnect from the internet after the page has loaded and it keeps working.
Local processing is not a cure-all: keep your computer up to date, and store the exported files as carefully as the statements themselves.
Try it with your own statement. LocalLedger reads the PDF or CSV in your browser, shows every transaction for review and checks the totals against the statement balances.
Convert locally — nothing is uploaded
