Everything below is free, without a watermark, a trial or a sign-in:
- Read: tabs, continuous or two-page views, fast search, bookmarks, split view, dark pages for night reading, Read Aloud.
- Fill & Sign: fill any form, type anywhere on a page, add a handwritten signature or initials.
- Digital signatures: sign with a certificate, smart card or Windows Hello, add a trusted timestamp, verify existing signatures.
- Comment and draw: highlight, notes, stamps, pen, shapes, arrows, text boxes, callouts, measurements.
- Edit text and images on the page; links, headers and footers, page numbers, watermarks.
- Organize pages: reorder, rotate, insert, extract, split, crop and merge files.
- Redact for real: the text and images underneath are removed, not just covered, then checked for leftovers. Sanitize hidden data.
- OCR, export and convert: make scans searchable (on your PC, with Windows' own recognizer), export to Word or Excel, make PDFs from Office files, web pages and images, PDF/A, password protection, reduce file size.
- Create forms, compare two versions, run batches on many files, and check accessibility (PDF/UA).
- Optional AI assistant, off by default: bring your own (Ollama, LM Studio, or a service with your own key). Inkvolt shows exactly what text is sent, and where, before anything goes.

A lean replacement for heavy printer apps: no printer-maker account, no cloud, no background services.
- See whether the printer is ready, ink or toner levels, paper problems and usage, live.
- Finds network printers by itself (HP, Canon, Epson, Brother and any AirPrint, Mopria or IPP Everywhere printer); USB printers already set up in Windows show up too.
- Scan from the glass or the feeder to a searchable PDF or JPEG, several pages at a time, with cropping, straightening, blank-page skipping and one-click presets.
- Copy (ID cards too), print photos and PDFs, manage the print queue, fix a paused or offline printer.

Inkvolt is made by one developer, Bermudez Systems. If it saves you a subscription, star the repository, leave a rating in the Microsoft Store, or tell a friend. Bugs and ideas: issues.
Inkvolt is independent and not affiliated with Adobe, Foxit, PDF-XChange, PDFgear, HP, Canon, Epson or Brother. Their names are trademarks of their owners, used here only for comparison.
Two apps, for Windows and the Mac, in one repository. Each is its own app with its own store listing; they share code and install together.

The license of each folder is in its LICENSE. At the top level, LICENSE is the AGPL-3.0 text (Inkvolt
PDF's) and LICENSE-MIT the MIT text, which covers the top-level scripts. Inkvolt PDF's
AGPL applies to Inkvolt PDF as distributed (the MIT libraries in it stay MIT on their own); Inkvolt Print ships no AGPL
code.
git clone https://github.com/gabandres/inkvolt.git
cd inkvolt
dotnet build Inkvolt.slnx # both apps, the shared libraries and the tests
dotnet test Inkvolt.slnxNeeds the .NET 10 SDK on Windows 10 (19041) or later, x64 or ARM64. Each app also builds on its own from its folder
(pdf/InkvoltPdf.slnx, print/InkvoltPrint.slnx). Settings shared by every project are in Directory.Build.props;
pdf/Directory.Build.props adds Inkvolt PDF's own (embedded PDBs, ARM64 by default).
pwsh -NoProfile -File install-suite.ps1 # publishes both, installs to %LOCALAPPDATA%\Programs\Inkvolt\InkvoltPdf and \InkvoltPrint
pwsh -NoProfile -File install-suite.ps1 -NoBuild # install the existing publish outputs (pdf/publish, print/publish)
pwsh -NoProfile -File install-suite.ps1 -Uninstall # removes only what it added, and puts back registry values it replacedIt adds a Start Menu folder "Inkvolt" with both apps ("Inkvolt PDF", "Inkvolt Print"), App Paths entries (InkvoltPdf.exe,
InkvoltPrint.exe: how each app finds the other) and Inkvolt PDF's "Open with" entries. Registry keys are only created
when missing (never re-created, which would wipe their values); each value set is recorded, with the value it replaced,
in Inkvolt\inkvolt-suite.json for -Uninstall. pdf/install.ps1 still installs Inkvolt PDF on its own.
Both apps keep their settings in %LOCALAPPDATA%\InkvoltPdf and \InkvoltPrint. On first start each moves its folder
over from the name it had before the rename, once; Inkvolt Print also moves its saved printer passwords in Credential
Manager. The installers don't remove an install made under the old names: uninstall that with the old scripts first.
