PDF Scanner & Editor by Sathi

PDF Sathi Studio is a fast, Android-friendly PDF workspace built for practical day-to-day file tasks. It helps users edit PDFs with watermark text, signatures, page rotation, and page numbers, merge multiple PDF files into one export, split PDFs by range, chunk size, or one page per file, fill existing PDF form fields, convert PDF pages to PNG, JPG, or TXT, and create lighter PDF copies for quick sharing.

The app also includes scanner-style image to PDF tools with original, enhanced, warm, cool, grayscale, and black and white looks, plus an in-app vault for opening, sharing, and managing saved exports later. The interface is designed for phone screens, with local-first workflows, quick sharing, and practical document tools in one place without requiring an account for basic use.

PDF Sathi Studio is focused on practical PDF workflows and does not claim affiliation with any other PDF brand or service. Some advanced scanned-document OCR and arbitrary embedded-text rewriting are not included in this version. This release uses Google Mobile Ads integration with live AdMob IDs configured for testing and release.
