Reveal.js to GZ Converter
Processing entirely on your device — large files may take a moment.
Reveal.js HTML Slides and Gzip Compressed File exist for different jobs: Reveal.js is the de-facto HTML presentation framework — one self-contained HTML file that turns headings and lists into a keyboard-navigable slide deck with transitions, speaker notes and PDF export built in. Unpack a .gz into a normal file or repack it as ZIP/TAR when the receiving tool does not understand gzip.
This converter runs entirely in your browser using WebAssembly — your files never leave your device, nothing is uploaded, and there are no watermarks, sign-ups or queues. Drop in several files at once to convert them as a batch.

About the Reveal.js format
Reveal.js turns a single HTML file into a full presentation: keyboard-navigable slides, transitions, speaker notes, fragments and even built-in PDF export. The converted file references the Reveal.js runtime from a CDN, so it runs in any browser — nothing to install, nothing to upload.
Headings become slide titles and sections become decks of slides; lists render as fragments you can step through. It is the fastest way from written content to a talk that works on any screen — and the file stays yours, editable in any text editor.
+Strengths
- ✓One file, runs in any browser
- ✓Speaker notes, fragments and PDF export built in
- ✓Editable as plain HTML afterwards
!Limitations
- −Needs internet for the CDN runtime
- −Design is template-driven, less bespoke than PPTX
- −Complex diagrams need hand-written HTML
About the GZ format
A .gz file is one file squeezed by gzip — not an archive. kernel.org tarballs are “tar inside gz”, but plenty of logs, JSON dumps and CSV exports travel as plain .gz. Opening one means decompressing it back to the original bytes.
Repacking into ZIP or TAR gives the decompressed file a container that every GUI tool opens without a second thought.
+Strengths
- ✓Everywhere on Linux and macOS
- ✓Fast, well-understood compression
- ✓Streams natively from any tool
!Limitations
- −Single file only — no directory tree
- −No encryption or integrity metadata

Frequently asked questions
Is this Reveal.js to GZ converter really free?
Yes — completely free, with no sign-up, no watermark and no daily conversion limits. The site is supported by advertising.
Are my files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so your files never leave your device — that is what makes it instant and private.
Does it work on Windows, Mac, iPhone and Android?
Yes. Anything with a modern browser works: Windows, macOS, Linux, Android and iOS. No software installation is required.
Is there a file size limit for Reveal.js to GZ?
The only limit is your device's memory, since nothing is uploaded. Files up to a few hundred megabytes work fine on a modern desktop browser; very large files simply take a little longer.
What about folders and directory structure?
The full directory tree is preserved: folders stay folders, and deep paths arrive exactly as they were packed in the Reveal.js file.
Is there a size limit for archive conversion?
There is no upload cap because nothing is uploaded — the practical limit is your device memory. A few hundred megabytes of unpacked content works comfortably on a modern computer.
