SaveTokens is a free, browser-based file to Markdown converter. We built it because we were tired of paying unnecessary AI API costs caused by inefficient document formats. Now it is free for everyone.
The Web Hunters team works on AI-powered applications and content systems every day. We noticed that a large fraction of the token budget in our AI API calls was being consumed not by the content we wanted the model to analyse, but by format overhead from PDFs, DOCX files, HTML pages, and other binary formats. Converting documents to Markdown before inserting them into prompts reduced our token count dramatically, often by 60 to 80 percent. The cost savings were immediate and significant.
We searched for a tool that would handle this conversion reliably, support all the formats we use, and not require an account or subscription for what is fundamentally a simple text processing task. We could not find one that met all three requirements. So we built SaveTokens and made it free for everyone to use.
SaveTokens converts files in 14 different formats to clean, structured Markdown text. The supported formats include PDF documents, Word DOCX files, Excel XLSX spreadsheets, PowerPoint PPTX presentations, plain TXT files, HTML web pages, CSV data files, JSON data files, PNG and JPEG images (via OCR), MP3 and WAV audio files (via transcription), EPUB eBooks, and LibreOffice ODT documents.
Every conversion happens via the SaveTokens API, which uses advanced document processing technology developed and maintained by The Web Hunters. The conversion pipeline handles the complexity of extracting clean text from binary document formats reliably, and is capable of reducing AI prompt token counts by up to 70 percent.
We do not store your files after conversion. Files uploaded to the SaveTokens API are processed in memory and the resulting Markdown is returned to your browser. We do not log file contents, do not train any models on your documents, and do not share your data with third parties. For complete details, see our privacy policy.
We recommend avoiding uploading sensitive personal data, medical records, financial documents, or any document whose confidentiality is legally protected. While we do not store files, best practice is to only upload documents you would be comfortable sending via email.
SaveTokens runs as a static HTML, CSS, and JavaScript site hosted on Hostinger and served via Cloudflare's global CDN. The conversion API runs as a Python service on HuggingFace Spaces using The Web Hunters' advanced conversion technology. This architecture keeps costs low, which is how we can offer the service for free.
The front-end has no dependencies on third-party JavaScript frameworks or CDN-hosted libraries. Everything is self-contained. This means SaveTokens loads fast on any connection speed and works correctly without requiring access to external CDN domains.
The Web Hunters is a digital product studio that builds web applications, AI integrations, and content systems. We publish tools and resources that help developers and content teams work more efficiently. SaveTokens is one of our free utilities. You can learn more about our work at thewebhunters.com.
We actively maintain SaveTokens and respond to feedback. If a file type you need is not yet supported, if you encounter a conversion error, or if you have ideas for improving the tool, please reach out via the contact page. We read every message.
