Frequently Asked Questions

Everything you need to know about converting documents to PDF

How does browser-based document to PDF conversion work?
For text and image formats, conversion happens entirely in your browser. Your file is read locally using the File API, parsed into a normalized document model, and rendered into a PDF using the pdf-lib library. You can customize page size, orientation, margins, compression, and more before converting. No data ever leaves your device.
Is my data safe when converting documents to PDF?
Yes, 100%. Your files never leave your device for browser-based conversions. There are no file uploads, no server storage, and no third-party services involved. Your documents remain completely private and secure.
Which formats are converted entirely in the browser?
TXT, Markdown, HTML, RTF, CSV, JSON, XML, DOCX, EPUB, ODT, MOBI, AZW3, FB2, and images (PNG, JPG, JPEG, WEBP, SVG, BMP, TIFF) are converted entirely in your browser. EPUB, ODT, MOBI, AZW3, and FB2 e-books are parsed chapter by chapter on your device, so they never need to be uploaded. Formats that cannot be reliably converted in the browser — such as PPTX, XLSX, ODS, and TIFF — are clearly marked and ready for a server-side conversion module.
Can I preview my document before converting?
Yes. The live preview panel renders text formats as formatted content, shows image thumbnails with zoom, and updates instantly as you change settings like page size, orientation, and margins. Every change to the settings panel updates the preview in real time.
What page and PDF options are available?
You can choose from A4, Letter, Legal, A3, or A5 page sizes with portrait or landscape orientation, plus small, normal, large, or custom margins. PDF options include output compression, font embedding, hyperlink preservation, image preservation, print/web optimization, and page numbering.
What is the maximum file size I can convert?
Each document can be up to 100 MB. Image batches support up to 50 images. For very large files the browser may need more memory and time — if you hit performance limits, try converting in smaller batches.
Does this tool work offline?
Yes. Once the page has loaded and the PDF processing library has been fetched, all browser-based conversions work without an internet connection since everything runs locally.
What makes ForgePlug's Document to PDF Converter different?
It is a full document studio, not a simple upload-convert-download form. You get a live preview, granular page and PDF options, a responsive workspace that adapts to your screen (split layout on desktop, step-by-step wizard on mobile with sticky preview), and complete privacy — your files never leave your device.

About Document to PDF Conversion

A complete guide to converting documents to PDF in your browser.

Why Convert Documents to PDF?

PDF is the universal document format — it preserves layout, fonts, and images exactly as intended across every device and operating system. Converting your Word, Markdown, HTML, or image documents to PDF makes them print-ready, tamper-resistant, and easy to share or archive. Because PDFs render identically everywhere, they are the standard for contracts, reports, resumes, e-books, and portfolios.

Understanding Page Size and Orientation

Page size determines the dimensions of each PDF page. A4 is the international standard, Letter is the US standard, and Legal is longer for contracts. A3 is ideal for large diagrams or posters, while A5 works well for compact booklets. Orientation lets you choose portrait (tall) or landscape (wide) — landscape is perfect for spreadsheets, presentations, and wide tables.

Browser-First Conversion & Privacy

ForgePlug's Document to PDF Studio performs conversions directly in your browser whenever technically possible. This means your documents are never uploaded, never stored, and never seen by any server. Even EPUB, ODT, MOBI, AZW3, and FB2 e-books are parsed locally — containers are opened, chapter spines are read, and every chapter is rendered to PDF on your device. Formats that browsers cannot reliably convert client-side — like PowerPoint or Excel — are clearly flagged, with the architecture ready to plug in a server-side conversion module when needed.

How to Convert a Document to PDF

Drag your file into the drop zone or paste text directly (Ctrl/⌘+V) for Markdown, HTML, or plain text. The studio auto-detects the format and shows a live preview on the right before you convert anything. Pick your page size (A4, Letter, Legal, A3, or A5), orientation (portrait or landscape), margins, and font, then click Convert — for supported formats the PDF is generated entirely on your device in a second or two, with no upload step in between. Download the result or start over with a new file.

Common Use Cases

Converting a Markdown README or blog draft into a clean, shareable PDF; turning an EPUB or MOBI e-book into a PDF for a device or app that doesn't read those formats; producing a print-ready PDF from an HTML snippet or scraped web page; and archiving CSV or JSON data as a formatted, human-readable document instead of a raw data file.

Tool Overview

A closer look at Document to PDF Converter — how it works, who it's for, and where it fits in your workflow.

PDF is the universal exchange format — it looks the same on every device and can't be silently edited — which is why you keep needing to convert other documents into it. The Document to PDF converter is a universal studio that turns DOCX, TXT, Markdown, HTML, RTF, CSV, JSON, XML, and images into polished PDF documents, directly in your browser where supported.

You're not limited to file uploads: paste raw text, Markdown, or code and convert that too. Once your content is loaded, a live preview shows exactly how the output will look while you adjust page size (A4, Letter, Legal, A3, A5), orientation, margins, compression, fonts, and page numbering. That makes it a genuine alternative to desktop office suites for everyday document production.

Browser-based conversions run entirely on your device, so documents with sensitive content — contracts, briefs, personal notes — are never uploaded. For formats that require processing your device can't do natively, the tool explains what happens instead of silently failing. No account, no watermark, no per-file limits.
