Best HTML viewer for iPhone — an honest comparison
Updated June 2026 · What to use depends on the job. Here's the truthful breakdown.
TL;DR: for a one-off look at a simple page, the built-in Files + Safari route is fine and free. If you edit code on your phone, get a code editor (Textastic, Koder). If your HTML comes from AI tools — single-file pages with scripts, charts and animations that you want to read offline, keep organized, and share as images — that's the job AI Artifact Reader is built for.
The contenders
Files + Safari (built-in): Quick Look previews .html; share-to-Safari renders more fully. No library, no export, external resources need internet. Free.
Documents by Readdle: excellent general file manager with a built-in browser-style preview. Not focused on rendering fidelity for script-heavy single-file pages, no long-image export of a rendered page. Free with upsells.
Code editors (Textastic, Koder): syntax highlighting, file trees, preview panes. Built for editing, not reading; no offline-by-default privacy posture; no artifact-style export. Paid.
Htmllit (HTML预览查看器): a lightweight HTML preview utility on the CN App Store. Quick previews; doesn't aim at the full AI-artifact workflow (library + offline guarantee + long-image/PDF export).
AI Artifact Reader: a reader purpose-built for AI-generated HTML & Markdown — paste-to-view, full JS/chart/animation rendering, network blocked by default, folders & search, export full-length image/PDF, multi-file bundles. Free to read; Pro for export & multi-file.

We build AI Artifact Reader, so weigh this page accordingly — but the table is factual, and the other tools genuinely win their own categories: Documents for general file management, Textastic/Koder for editing. If you don't care about offline privacy, exports or AI output, the built-in route costs nothing.
Pick by job
“I just need to peek at one simple .html” → Files + Safari.
“I edit HTML/CSS/JS on the go” → Textastic or Koder.
“I manage lots of mixed files” → Documents by Readdle.
“ChatGPT/Claude keeps giving me HTML & Markdown and I want to read, keep and share it — privately” → AI Artifact Reader.
