IStanPdf is an offline Android utility for PDF and DOCX operations. There are no subscriptions, internet requirements, or file size limits. I built this as a fast, local alternative to freemium online tools like iLovePDF and Smallpdf. Everything runs directly on your device.

-
DOCX Remove Pages: Some DOCX files with structural issues fail to save during the "Remove Pages" operation.
- Workaround: Use "Reorder Pages" instead - it internally converts the DOCX to PDF to bypass the limitation.
- Caveat: If you later convert the resulting PDF back to DOCX, some elements may no longer be editable.
-
App Size: IStanPdf is larger than a typical utility app because it bundles LibreOffice binaries, which power the DOCX operations.
-
UI: The interface is functional but a bit rough right now. I'm planning some micro-optimizations to make it more accessible.
-
Monolith Architecture: Core operations currently live in a singleton
MainActivity. I plan to refactor this into a modular architecture in future updates to make debugging and maintenance easier.
- Refactor Architecture: Refactor code from monolith to a better architecture for easier debugging.
- Compress PDF: Introduce Compress PDF feature.
- Optimize DOCX: Optimize DOCX operations.
- Auto DOCX Repair: Introduce auto DOCX Repair feature to fix structural issues in DOCX making it difficult to be saved.
As a CS student, I regularly needed PDF and DOCX tools but found most online options too slow or restricted by paywalls. I couldn't find a lightweight offline alternative, so I built this.
Vibecoding doesn't mean you don't know how it's done. I am a 1st-year CS Engineering Student, and I am actively learning. My ultimate aim is to manually code everything and eventually ditch vibecoding.
