How to Convert Latex To PDF
LaTeX produces beautifully typeset documents for academic papers, theses, and scientific publications — but compiling .tex files locally requires a full TeX distribution that can be 4 GB or more. SublimePDF's LaTeX-to-PDF API compiles your .tex source remotely using a full TeX Live distribution, returning a publication-ready PDF without any local installation.
Follow the step-by-step instructions below, then use the free tool directly — no registration or download required.

Prepare your LaTeX source
Ensure your .tex file compiles successfully with standard packages. SublimePDF supports pdflatex, xelatex, and lualatex engines. If your document uses custom .sty or .cls files, include them in your upload.
Upload the source files
POST to /api/v1/latex-to-pdf with your .tex file as multipart/form-data. If your project has multiple files (bibliography .bib, images, custom classes), upload them as a ZIP archive and specify the main .tex filename with the 'entryFile' parameter.
Select the compilation engine
Set the 'engine' parameter to 'pdflatex' (fastest, for standard documents), 'xelatex' (for Unicode and system fonts), or 'lualatex' (for advanced font features and Lua scripting). Default is pdflatex.
Configure compilation passes
For documents with bibliographies (BibTeX/BibLaTeX) or cross-references, set 'passes' to 2 or 3 to ensure all references resolve. Single-pass compilation is faster but may show '??' for unresolved references.
Download the compiled PDF
On success, the API returns the PDF binary. If compilation fails, you receive a JSON error response containing the LaTeX log output so you can debug the issue.
Pro Tips
- 💡 Always test your .tex file locally with the same engine before using the API — the API mirrors TeX Live 2024, so package compatibility is identical.
- 💡 Use the 'xelatex' engine if your document uses UTF-8 characters, OpenType fonts, or non-Latin scripts — pdflatex struggles with these.
- 💡 Include a .latexmkrc configuration file in your ZIP archive to automate multi-pass compilation with bibliography and index processing.
- 💡 If you need specific CTAN packages not in the base distribution, list them in the 'packages' array parameter and the API will install them before compilation.
Privacy & Security
All processing happens directly in your browser. Your files are never uploaded to any server — they remain on your device throughout the entire process. SublimePDF uses WebAssembly technology for fast, secure, client-side processing.
Works Everywhere
This tool works on any modern browser — Chrome, Firefox, Safari, or Edge — on desktop, tablet, or mobile. No software to install. PDF is an open ISO standard supported by all major platforms.

How to Convert Scanned PDF to Text
Scanned PDFs are essentially images — you can't select or search the text. OCR (Optical Character Recognition) technology converts these image-based PDFs into searchable, editable text. SublimePDF's OCR tool handles this conversion right in your browser.
How to Convert PDF To Grayscale
Printing color PDFs on black-and-white printers often produces muddy, hard-to-read output because the printer's automatic color conversion isn't optimized for clarity. Pre-converting your PDF to grayscale ensures consistent, clean results on any mono printer and can dramatically reduce printing costs for large jobs. SublimePDF converts all colors—in text, images, and vector graphics—to properly weighted grayscale.
How to Convert Emails To PDF
Archiving emails as PDFs preserves the complete message—headers, body, formatting, and attachments—in a universal format that doesn't require any email client to view. Legal compliance, business record-keeping, and personal archiving all benefit from having emails in a searchable, printable, tamper-evident PDF format. SublimePDF converts email files from Outlook, Gmail, and other clients into clean, well-formatted PDFs.
