PDF to OFX converters:
online upload vs on-device.

What a PDF-to-OFX converter actually does

A PDF bank statement is a picture of a table, not data. Every PDF-to-OFX tool — online or on-device — runs the same three-stage pipeline: recognize the transaction table on the page, turn each row into a typed transaction (a date, a description, a signed amount), then write those transactions out as an OFX file your finance software can import. The differences between tools are in where that pipeline runs and how well it handles a messy statement, not in what the pipeline is doing.

PDFs make that harder than it looks. Bank statements repeat their header row on every page, which a naive parser reads as extra transactions. Many banks write a negative amount in parentheses instead of with a minus sign. Some split debits and credits into two separate columns that a converter has to merge into one signed amount, and get the sign backwards for a credit-card statement, where a charge and a payment run in opposite directions from a checking account. A converter that handles these correctly on the first try, without you fixing anything by hand, is doing the actual hard part of the job.

Where your statement goes: three models

However the parsing works, your statement has to be processed somewhere, and there are three places that can happen.

• Web upload. You upload the PDF to a provider's server, it is processed there, and you download the result. What happens to the file after that is whatever the provider's own retention policy says — some state a specific retention period, some do not.
• Desktop software. You install an application on a Windows PC or a Mac, and the file is processed locally by that program. It stays on your computer, though the software itself may still need occasional internet access for licensing or updates.
• On-device mobile. The conversion runs inside an app on your phone or tablet, using the device's own frameworks, and the file never leaves it. This is where Filemorph sits — the on-device option, on iPhone, iPad and Mac rather than a Windows desktop.

Comparison

When Filemorph is not the right tool

An honest comparison includes the cases where the other column wins. Filemorph is not the right tool if:

• You need QFX or QBO output. Filemorph writes plain OFX 1.02 only. QFX is a licensed variant it does not produce, and it does not write QBO either. If your software strictly requires one of those, check its import menu first — many also accept plain OFX.
• You're on an older device. The conversion requires iOS 26, iPadOS 26 or macOS 26. An iPhone or iPad still on iOS 18 or earlier, or an Intel Mac that cannot run macOS 26, cannot use it.
• You want a Windows desktop workflow. Filemorph is an Apple-platform app — iPhone, iPad and Mac. There is no Windows version.
• You process a high volume of statements. Filemorph shows a review sheet for every statement so you can confirm the columns and sign convention before exporting. That's a deliberate accuracy check for one or a handful of statements a month; it's a poor fit for hundreds of statements a month, where a batch pipeline with no per-file review is what you actually need.

Privacy checklist for any converter

Whichever tool you use, ask the same four questions before you hand over a bank statement:

• What is the stated retention period? "Processed and deleted" is a claim you can hold a provider to; "we may retain data" is not.
• Are there named sub-processors? A privacy or terms page that lists who else touches the file — a cloud host, an OCR API, an analytics vendor — tells you how many parties actually see it.
• Does the free tier keep files longer than the paid tier? Some services use free-tier uploads to improve their own models. Check whether that applies before using the no-cost option for anything sensitive.
• Is there an offline mode at all? If a tool needs a network connection to function, the file is going somewhere outside your device by definition.

The tie-breaker is the Airplane Mode test: turn on Airplane Mode and try the conversion. If it still works, nothing left your device. If it doesn't, something needed a network — which means your statement did too. Filemorph passes that test, because there's no server in its conversion path to reach. See exactly what the app can and can't send over a network on the transparency page.

How to do it on-device

The on-device path is three steps: open the statement PDF in Filemorph, choose the To OFX operation and confirm the detected columns in the review sheet, then export the .ofx file to Files or AirDrop it to your Mac and import it into GnuCash, YNAB or Xero. The PDF to OFX conversion page covers the operation itself; the full step-by-step guide walks through getting the PDF onto your iPhone, reading the review sheet, and importing into each of the three apps, plus fixes for statements that don't parse cleanly on the first try.
