Instantly detects MIME types and extensions for PDFs, Word files, spreadsheets, markdown, and images, automatically mapping allowed conversion outputs.
Files and pasted texts are processed in memory and returned directly as downloads. Zero database logs, zero file tracking, zero third-party telemetry.
Compare documents with identical extensions or pasted text blocks with instant similarity metrics and color-coded line-by-line syntax diffs.
Built on optimized FastAPI and native Python document libraries for fast transformations without heavy external binary overhead.
Find quick answers about document transformations, file formats, comparison algorithms, and security.
DocShift supports 10+ standard formats: PDF, Microsoft Word (DOCX), Markdown (MD), HTML, Plain Text (TXT), CSV, JSON, Microsoft Excel (XLSX), and Images (PNG, JPG, WEBP, BMP). You can convert documents to PDFs, spreadsheets to JSON/CSV, images to WebP/PDF, and markdown to HTML/Word effortlessly.
DocShift offers dual comparison modes: you can upload two documents sharing the same format (e.g. two DOCX or two PDF files) or paste two texts directly. The engine tokenizes both files, calculates a similarity percentage score, and highlights added, deleted, and modified lines in a synchronized side-by-side table.
