Could you build this?

No True in-place PDF text editing with font matching and reflow in the browser requires deep knowledge of the PDF specification, font subset parsing/embedding, and complex typographic layout engines.

What it would actually take: A production PDF editor that modifies existing text in its original font requires parsing the PDF DOM, extracting embedded font glyph tables (CFF/TrueType/Type 3) and encoding maps, recalculating character advances, and handling text matrix transformations. The stack would typically use C++/Rust compiled to WebAssembly (such as MuPDF or PDFium) with custom layout reflow logic. Building this demands deep low-level expertise in the ISO 32000 PDF standard and digital typography.
