What is a UDF file and why won’t it open?
UDF is the document format used by UYAP, Türkiye’s national judiciary IT system. Case files, court records and expert reports are delivered with this extension. Because it is not a common format like Word or PDF, double-clicking it does nothing.
Normally you need to install the UYAP Document Editor, which requires Java, does not run everywhere and has no mobile version. This page removes that step: drop the file in your browser and read it. No install, no sign-up, no fee.
Is UDF-viewer gratis?
UDF-viewer is volledig gratis: geen account, geen registratie, geen watermerk en geen advertenties. Het werkt online — open het gewoon in je browser op telefoon, tablet of computer; je installeert niets.
Je bestanden worden na de bewerking van de server verwijderd; ze worden met niemand gedeeld en de inhoud wordt niet bekeken. Er is geen daglimiet, geen proefperiode en geen verborgen kosten.
Why use this viewer
No UYAP Editor needed
No Java, no software install, no administrator rights. A browser is enough.
Works on mobile
The UYAP Document Editor has no mobile version. Here you can read a case file from your phone.
Formatting preserved
Alignment, bold/italic/underline and tables are shown as they are — not flattened to plain text.
Your file stays yours
The uploaded file is deleted after processing. No account, no email required.
Frequently asked questions
Can I open a UDF file without the UYAP Editor?
Yes. This page opens .udf files in your browser — no UYAP Document Editor required.
Can I open UDF on a phone?
Yes. The page works on phones and tablets, which is the practical way to read UDF on mobile since the UYAP editor has no mobile version.
Can I convert UDF to Word or PDF?
Yes. Once the document is open, press “Download PDF” or “Download Word” — you do not need to upload the file again.
Is my file stored on the server?
No. Your file is deleted after processing. No sign-up, no email, no payment.
Does it open digitally signed UDF files?
It shows the document’s text and formatting. It does not validate the electronic signature — use UYAP’s own tools for signature verification.
Is there a file size limit?
You can open a UDF of up to 25 MB at a time. Typical case documents are far smaller.
