Osenpa
Local PDF Tools for Windows
Osenpa PDF Tools
Handle recurring PDF merge, split, OCR, compression, watermark, protection, cleanup, and batch work locally.
Quick answer
What is Osenpa PDF Tools best for?
Osenpa PDF Tools is a free Windows PDF suite for people who need merge, split, organize, compress, convert, OCR, watermark, password, cleanup, and batch workflows without uploading documents. It processes supported tasks locally on Windows 10 or 11 and is designed for recurring document work rather than collaborative online editing. It is not a real-time collaborative PDF editor.
What's new in Osenpa PDF Tools 1.0.2
Osenpa PDF Tools 1.0.2 Update
Osenpa PDF Tools 1.0.2 is a maintenance release focused on better PDF compression, clearer local-first privacy wording, improved reminder timing, and cleaner EXE/MSIX packaged releases.
Better PDF Compression
Compression was improved for image-heavy and scanned PDFs, with clearer quality-first, balanced, strong, and target-size workflows.
Smarter Size Goals
Size-goal suggestions now respond more closely to the selected file and expected compression behavior.
Review and Donation Timing
Microsoft Store review reminders were added, and donation/review prompts now use rolling 30-day windows to avoid stacked popups.
Clearer Privacy Wording
In-app text now explains that normal PDF work stays on the device, offline use is supported, and network access is limited to explicit actions.
Interface and Localization Polish
Header, footer, localized labels, workflow wording, and cancel behavior for running jobs were refined.
Updated Release Packages
Release metadata and packaged outputs were refreshed for standalone EXE and Microsoft Store/MSIX users.
Downloads, mirrors, and verification
Resource Links
Microsoft Store is the recommended channel. Direct installer and mirror links are available for users who need a standalone download. Osenpa PDF Tools is a desktop app, so large PDFs and generated output files may require enough local disk space.
