Do I need to replace DocSend or Papermark to use HTMLRadar?

No. They solve the file-sharing case. HTMLRadar is for the separate case where the document itself is HTML and should stay that way for the reader.

Does DocSend accept HTML files?

DocSend’s published accepted-file list does not include HTML. It accepts common document, presentation, media, image, and spreadsheet formats instead.

How should I test the right product quickly?

Send one real document. If a PDF or office file is the source of truth, test DocSend and Papermark. If the browser version is the source of truth, test the same HTML through HTMLRadar before converting it.

HTMLRadar · Comparison

DocSend vs Papermark for document sharing.

Updated August 2026

DocSend and Papermark are both built around uploading a file and tracking that file; Papermark is the open-source one. HTMLRadar is built around HTML: if what you send is a web page, an HTML deck or a Claude artifact, it keeps that format and reports reading by section. This page compares all three.

This is a decision between two document-sharing products, not a claim that one is always better. Start with the thing you need to send. If it is an uploaded office file, compare DocSend and Papermark. If it is a live HTML deck, brief, or proposal, use a tracker built to preserve that format.

The deciding question: file or live web page?

Your starting point	Best fit	Why
PDF, PowerPoint, Word, Keynote, or a file library	DocSend or Papermark	Both are built around sharing uploaded documents.
Self-hosted document sharing is a hard requirement	Papermark	Its public project describes a self-hosted, open-source document-sharing product.
An HTML deck, brief, proposal, or product page	HTMLRadar	The recipient reads the original HTML, with section-level read analytics added when it is served.

DocSend's supported-upload list includes PDFs, PowerPoint, Word, Keynote, media, and spreadsheets, but not HTML. Papermark's public repository describes its own self-hosted document-sharing model. DocSend source and Papermark source.

When DocSend is the stronger choice

Pick DocSend when the source is a conventional document and your team needs its mature file workflow: uploaded documents, spaces, access controls, watermarks, or e-signatures. Its accepted-file list is broad. That is useful when fidelity means a recipient sees a managed viewer for a familiar file format.

When Papermark is the stronger choice

Pick Papermark when the same document-sharing model is right, but source access and self-hosting matter to you. Its public project offers shareable document links, analytics, custom domains, and a self-hosted deployment path. Evaluate it on the workflow you will actually run, not on a generic feature checklist.

The case neither file tracker solves

A growing number of decks and client documents start as HTML: a Claude artifact, a reveal.js presentation, or a hand-built page. Turning one into a PDF removes the interactions and layout it was made for. HTMLRadar stores or fetches the HTML, serves it through a tracked link, and reports the sections that held attention.
