ArtiMax PDF Editor v1.0.40

Released 20 September 2026·Windows 10/11 (64-bit)· Source on GitHub· Release notes· Report an issue

A desktop PDF editor for Windows. View, annotate, edit, OCR, translate and convert PDFs — everything runs locally on your PC.

New in v1.0.40: Select Text just got faster — turn on Tools → Auto-Copy Selected Text (or tick “Auto-copy to clipboard” inside the prompt) and every Select-Text drag lands the extracted text on your clipboard the moment the region is captured. A themed toast briefly shows the first ~140 characters that went to the clipboard, plus the total character count, so you can confirm the right region was grabbed without pasting into another app.

Downloads are zips: many workplaces block bare .exe files. Unzip, then double-click the .bat inside — it clears the Windows download block for you and runs Setup (installer) or launches the app (portable).

Since v1.0.3: a Pan tool for dragging around a page; a one-click updater (scripts\Update ArtiMax PDF Editor.bat) so existing installs no longer need to re-run Setup; multi-window support (open several PDFs in separate windows); a dockable, customisable Tool Palette with dark-mode-friendly icon contrast; form checkboxes with click-to-toggle and uncheck-all; text effects (bold / italic / underline / strikethrough / colour) on annotations; OCR language data bundled again so OCR works out of the box.

⚠️ About the Windows SmartScreen warning

The first time you run the installer (or the portable exe), Windows may show a blue "Windows protected your PC" dialog from Microsoft Defender SmartScreen, saying it doesn't recognise the app. This is normal and doesn't mean the file is unsafe.

The .bat included in each zip normally clears the download block for you, so you may never see this dialog. If you extract the zip another way and run the app directly, the steps below still apply.

Why it happens

Windows shows this warning for any Windows program that isn't signed with a commercial code-signing certificate (~AUD $400–$500/year, mostly used by large software vendors). Independent and small-vendor apps almost always trigger this dialog on first launch. The warning disappears on its own after enough people have run the app without reporting problems.

How to run the app anyway

  1. Double-click the downloaded file.
  2. When the blue "Windows protected your PC" dialog appears, click More info.
  3. A new button appears at the bottom labelled Run anyway. Click it.

Windows remembers your choice — you'll only see the dialog once per downloaded file.
