Download PDF Studio

Pick your PC’s processor and how you want to install. No file contains a licence key; the key is applied at install time or on first launch.

Current release

1.3.0 Stable

16 September 2026

Windows 64-bit (x64)

For most PCs — Intel and AMD processors. Windows 10 or 11.

For Snapdragon and other ARM PCs. Needs Windows 11; the interface is native and the PDF engine runs under Windows’ built-in x64 emulation.

Verify before you deploy

Your IT department can confirm the file they received is the one we published — compare the result with the checksum above:

certutil -hashfile <file> SHA256

Built-in OCR pack (.zip)

For PCs that are never online: the app downloads it the first time OCR needs it, or install it from the file in Settings.

Download 29 MB In the app: ⁦Settings › Optional upgrades › Built-in OCR › Install from file⁩

32-bit Windows is not supported: the OCR, Office-conversion and AI engines need 64-bit.

New name, new address. PDF Studio is now published by ElixTechs, formerly NMTeches. The website is now pdfstudio.elixtechs.com, and the licence server is pdfstudio-licence.elixtechs.com.
Your licence carries on. Your licence key, seats and activation stay as they are. There is nothing to enter again, and no PC needs to be activated again.
Update every PC to keep activating. Version 1.2 and earlier still use the old nmteches.com addresses. Once those addresses are switched off, earlier versions cannot activate or renew their activation, and they stop working when the current activation runs out. Install 1.3.0 on every PC before then. IT departments should allow pdfstudio-licence.elixtechs.com, pdfstudio.elixtechs.com and s3.elixtechs.com.
A new look. ElixTechs colours, square corners and a new icon, in light and dark themes. The Start menu and desktop shortcuts are now called *PDF Studio by ElixTechs*, and the old shortcuts are removed when you update.

Edit Text and Find handle Arabic properly. Arabic words are found and replaced as whole words. This includes words next to numbers and PDFs that store lam-alef the other way round. A longer replacement no longer fails to fit, and it keeps the original size and line position.
Highlights. The Highlights list also finds text highlighted in Word and saved as PDF. Open it from View › Highlighted Text, with Ctrl+Shift+H, or by right-clicking a page. *Copy all* copies the listed text with page numbers and notes.
Arabic interface. Every Arabic label was reviewed for clearer, more consistent wording. Page numbers can now be written in Arabic (صفحة 1 or صفحة 1 من 10). Wrapped right-to-left text no longer loses its first letter.

All versions

The setup supports a silent install with the key applied from the command line:

PDF-Studio-Setup-1.3.0-x64.exe /S /LICENSE=PDFS1...

With the MSI, deploy the key file separately, to:

%ProgramData%\PDF Studio\license.key

The full deployment guide is sent with your key. See also the user guide.
