Document & file conversion tools

Convert between JSON, XML, YAML and CSV, export Markdown to PDF or Word, turn plain text into a PDF, open iPhone HEIC photos, and inspect any file — everything runs in your browser.

Note: Every conversion on this page happens locally: your files are never uploaded. The PDF and DOCX writers are real (pdf-lib and Office Open XML), so the downloads open in Word, Google Docs, Excel, Preview and every PDF reader.
