Upload-based vs in-browser statement converters

Bank statement converters fall into two architectures. Upload-based tools send your PDF to a server (and often to a third-party AI or OCR service). In-browser tools process it on your computer. Neither is automatically better. Here is a checklist you can apply to any tool, PennyTie included.

The checklist

1. Where does the file go?

Does the tool state that it uploads, and to which servers? Does it name sub-processors, such as an AI or OCR vendor? An in-browser tool can be checked yourself with the Network tab; see how. Upload-based tools can only be checked by reading their policy.

2. How long is it kept?

Look for a stated retention period, whether deletion is automatic, and what metadata (file names, page counts) remains in your account. "We take security seriously" is not a retention policy.

3. Does it check the balances?

Ask whether the tool compares the extracted transactions with the printed opening and closing balance, and what it does on a mismatch. A tool that always shows a clean table is not the same as one that tells you when the table is wrong. See why totals don't match.

4. Page and file limits

Free-tier pages, monthly page quotas, maximum file size, whether unused pages roll over, and whether a free preview lets you download or only view.

5. Scanned statements (OCR)

If your statements are scans or phone photos, you need OCR. If they are downloaded from online banking they are usually text PDFs and do not. See scanned vs text.

6. Export formats

CSV, XLSX, QBO, OFX, QIF? Which does your accounting software accept? See preparing a CSV for import.

7. Pricing model

Per document, per page, monthly subscription, or credit packs; whether annual billing is required to get the advertised price; how to cancel.

8. Password-protected files, editing, and support

Can you fix a flagged row in the tool? How are encrypted PDFs handled? Who answers email?

Typical differences

Criterion	Upload-based (typical)	In-browser (typical)	PennyTie specifically
File location	Sent to provider servers	Stays on your device	Stays in your browser tab; verifiable
Retention	Stated by provider; varies	None needed	None; nothing is received
Balance check	Varies; check the tool's page	Varies	Yes: totals and running balances
Scanned PDFs / OCR	Often supported	Often not	Not supported
Input	PDF, sometimes images	PDF	Text-based PDFs only, up to 25 MB
Export	Often Excel, CSV, QBO, OFX	Varies	CSV and XLSX (no QBO or OFX)
Page limits	Quotas per plan	Limited by your device	Free: 5 pages per file; Pro: unlimited
Pricing	Subscription, per-page or per-document	Varies	$0, or $9/month, or $79/year
Speed on huge batches	Server-side	Depends on your computer	One file at a time

"Typical" columns are generalisations, not statements about any named product. Always read a tool's own current pages. A few named examples, with links, are on the alternatives page.

How to choose

Confidential statements and text PDFs: favour a tool you can verify, and check the balances.
Scanned statements or very large volumes: you will probably need an upload-based service with OCR; then read its retention and sub-processor statements carefully.
Need QBO or XLSX directly: check the export list before you start.

Try it: open PennyTie, drop a text-based statement PDF (or use the built-in fictional sample) and see whether the totals tie out. Free for statements up to 5 pages; nothing is uploaded.
