Heavy-format file tools
PDFs, ZIP archives, photo metadata, font files, and SVGs — parsed by dedicated engines in workers, checked against signature and size limits before anything opens, and never uploaded.
- PDF inspector
Page count, page sizes, metadata, and which pages carry text — read from structure, nothing rendered.
- PDF page tools
Extract, delete, or rotate pages by an explicit spec — output re-loaded and verified before download.
- ZIP inspector & builder
List ZIP contents without inflating them — sizes, ratios, traversal flags — extract single entries or build a new archive.
- Photo metadata
See what a photo discloses — GPS, device, dates, software — then re-encode it clean, verified.
- Font inspector
Read TTF, OTF, and WOFF files — names, metrics, glyph count, tables, axes — with a sandboxed sample outline.
- SVG sanitizer
Disclose what an SVG carries — scripts, handlers, external refs — then get a copy that cannot fetch or run anything.
