When converting to PDF matters.
A PDF locks your formatting in place so it looks identical on every device, in every viewer, for every recipient.
Submitting job applications
Employers and applicant tracking systems expect PDFs. Converting your resume and cover letter ensures formatting is locked and looks identical on every device.
Sending contracts and agreements
A PDF cannot be accidentally edited the way a Word file can. Converting contracts to PDF protects the integrity of the document before sharing.
University and college submissions
Academic portals, assignment dropboxes, and grant applications typically require PDF. Converting your Word essay takes seconds.
Invoices and quotes
Sending an invoice as a PDF prevents formatting from shifting in the recipient's version of Word and ensures totals are displayed correctly.
Reports and presentations
Converting a report to PDF makes it easy to share via email or link, with confidence it will look identical for every reader.
Archiving documents
PDFs are a stable, long-lived format. Converting Word documents to PDF before archiving ensures they remain readable independent of future Word versions.
How it works under the hood.
When you drop a .docx file, mammoth.js parses the Office Open XML structure entirely in your browser, turning text, headings, lists, tables, and inline images into the preview you see on screen, without any server involvement.
The conversion itself runs in a Web Worker, off the main thread. Pandoc, compiled to WebAssembly, converts the .docx into Typst markup, and the Typst typesetting engine, also WebAssembly, lays it out and writes the PDF at your chosen page size (A4 or US Letter). Where your browser allows it, the fonts your document names are read from your system and embedded, so the output stays close to the original.
Your document never leaves your browser tab. No server receives it, and closing the tab clears all data from memory.
