Thanks for sharing this. A quick technical summary for anyone considering using it:

What the tool does:
It takes VAG firmware container files (FRF, ODX, SGO) and decrypts + unpacks them into raw .BIN files, reconstructed block-by-block according to the selected ECU protocol. Essentially the same process tools like VW Flash or ODX-Flash do internally before writing to the ECU.

Supported protocols (from the screenshots):

• VAG Simos 8.4 / 8.5
• VAG DSG DQ250 MQB
• (likely others in the dropdown — Simos 12/18, Bosch MED17, etc.)

How the free access works:

• Normally the conversion costs 8 tokens per file.
• Coupon code BINUNLOCK brings it to 0 tokens — free conversion.

Example shown:
The third screenshot shows a DQ250 MQB TCU firmware FL0D9300042M5013cPTKsw.frf being converted. The log shows:

• Step 1/3 — FRF decrypted
• Step 2/3 — 3 blocks parsed (2 KB @ 0x000000, 1216 KB @ 0x040000, 128 KB @ 0x020000)
• Step 3/3 — Output buffer built, final size 1504 KB

That 1504 KB output is consistent with a correct full DQ250 SW binary.

A few practical notes:

• Always verify the output BIN size and block layout against what your flashing tool expects for that specific ECU. A wrong protocol selection will give you a garbage binary.
• If you're converting for tuning purposes, make sure you know whether you need the sw (software/calibration) or hw (hardware/boot) container — for map editing you almost always want the SW FRF only.
• The tool outputs a raw flat binary. If your flash tool expects an encrypted/signed container back (e.g., for OBD flashing on newer Simos/MED17 ECUs), you'll still need to re-pack and sign after editing.
• As with any online converter handling proprietary firmware — consider what you're uploading and whether you're comfortable with that from a data/IP perspective.

Useful resource for those working with VAG FRF files without wanting to set up local decryption toolchains.

Thank you, what is the login?

you can register on the website and use yours.

Added more compatibility

Tool says it needs active subscription and code only gives 10% discount, not free to use.

it was free until it was on beta phase.
