Local file conversion with verifiable promises
ConvertRS publishes 98 conversion paths across 22 accepted input formats, plus dedicated PDF-page and favicon tools.
Explore tools and guidesHow it works
Supported conversions use Rust compiled to WebAssembly and browser APIs. The capability registry is the source of truth for published routes, inputs, outputs, and limitations.
What it does
ConvertRS runs published conversion pairs, organizes PDF pages, merges and splits documents, adds image pages, allows text, signatures and covering areas, and creates favicon packages from PNG, JPG, or WebP.
Current limits
PDF Studio does not change text already embedded in a PDF. Excel, XLSX, or ODS to CSV export uses the first worksheet and cached formula values; it does not preserve formatting, charts, images, comments, or macros. The favicon generator does not accept SVG, text, or emoji as source input.
Accessibility goals
The goal is keyboard navigation, visible focus, AA contrast, touch targets of at least 44 pixels, reduced-motion support, and pages that remain readable without JavaScript.
