indiPDF

A Native PDF Experience

Professional PDF editing built from the ground up for the desktop — fast, private, and fully featured.

Annotate & Mark Up Anything

A complete markup toolkit — and every annotation is written as a standard ISO 32000 PDF object, so it's visible in Acrobat, Foxit, Evince, and any other reader.

Highlight, underline, strikethrough with text snapping
Freehand drawing, shapes, arrows, and an eraser
Sticky notes that work even on scanned documents
Signatures: draw, type, or reuse saved signatures

Organize Pages Visually

Reorder, rotate, delete, crop, merge, and split with a thumbnail sidebar or a full grid overview — PDF Arranger style, without leaving the editor.

Drag-to-reorder thumbnails and a resizable grid view
Visual crop/trim with non-destructive CropBox
Merge multiple PDFs with form fields preserved
Split out pages or page ranges into new documents

Compress & Optimize

Shrink oversized PDFs with Ghostscript-powered compression and clear quality presets, with a before/after size comparison so you know exactly what you're getting.

Presets: Screen, eBook, Printer, and Prepress
Before/after file size display
PDF/A archival export (ISO 19005-1b, 2b, 3b)
Export pages as PNG, JPEG, or WebP images

15 bundled OCR languages, processed locally
Direct scanner integration (SANE, WIA)
Flatbed and document-feeder (ADF) support
Multi-page scanning with automatic PDF assembly

Frequently Asked Questions

How much does indiPDF cost?

$35 for a lifetime license. Once purchased, you'll never pay for updates or new versions. No subscriptions, no recurring fees — ever.

Is indiPDF open source?

indiPDF is a commercial, closed-source product — but your purchase directly funds open-source software. Revenue from indiPDF and indiAccounting pays for the development of indiBudget, our free and open-source personal finance app, with more open-source tools on the way. A one-time purchase keeps the whole project sustainable without subscriptions or ads, and helps us give more software away for free.

Can I try it before buying?

Yes. indiPDF is fully functional without a license — the only limitation is that saved files include a small watermark. Purchase a license to save files without the watermark.

Does indiPDF respect user privacy?

Absolutely. Your documents never leave your computer — no cloud uploads, no tracking, no data collection.
