Office conversion

Office to PDF, locally

First implementation: extract OOXML text from DOCX/PPTX/XLSX and print it into a clean PDF.

This is not pixel-perfect Office rendering. True lossless Office-to-PDF requires a full layout engine, font metrics, pagination and chart renderer, usually delivered as a large WASM core.

底层 WASM 加速引擎检测当前浏览器是否支持 SIMD、SharedArrayBuffer 和线程化 WASM,为后续 Office 排版/压缩核心选择最快运行时。

User guide

How to use Office to PDF Adapter

Convert supported Office content through available browser renderers while clearly exposing fidelity limits.

  1. 1

    Upload a supported DOCX, XLSX, or presentation file.

  2. 2

    Inspect fonts, images, sections, tables, and unsupported elements.

  3. 3

    Generate the browser-rendered preview.

Best for

  • Simple office documents
  • Private local conversion experiments

Important limitation

Perfect Microsoft Office layout parity is not available without a compatible Office-grade rendering engine and licensed fonts. Macros, charts, SmartArt, equations, and pagination may differ.

Frequently asked questions

Is conversion pixel-perfect?

No. Browser libraries do not reproduce the complete Microsoft Office layout engine.

Are macros executed?

No. Untrusted active content should never be executed during conversion.

PDFPerch processes files locally unless this guide explicitly identifies a cloud-dependent feature. Always keep an original copy and verify critical output before submission, printing, signing, or accounting use.
