DOCX now previews locally; other Office and archive formats can later move to an independent preview service.

File Preview opens DOCX, PDF, image, audio, video, text, code, and Markdown files locally in the browser, which is useful for quick inspection without uploading content. Up to 30 files can be added at once.

Each file is limited to 50MB, while text, code, and Markdown files are limited to 5MB. DOCX layout is approximated in the browser; other Office documents and archives still use the reserved server-preview entry. Large PDFs render in batches.

FAQ

DOCX layout is approximated in the browser, so complex fields, special fonts, and automatic pagination may differ slightly from desktop Word.

Why are all pages of a large PDF not shown at once?expand_more

Pages are rendered in batches to keep the browser responsive. Use the load-more control to render later pages.
