ODP to GZ Converter
Processing entirely on your device — large files may take a moment.
ODP is the OpenDocument presentation format — LibreOffice Impress’s native deck, also opened by PowerPoint and Google Slides. Unpack a .gz into a normal file or repack it as ZIP/TAR when the receiving tool does not understand gzip.
Because the whole conversion happens on your device, it is instant, unlimited and genuinely private — no accounts, no watermarks, no files on anyone's server. Multiple files are converted in one go.

About the ODP format
ODP is the OpenDocument presentation — LibreOffice Impress’s native format, built on the same zip-of-XML idea as PPTX. Files come from public institutions, lecture archives and anyone standardised on open formats.
As with PPTX, text extraction gives you every word in slide order, without the visuals. That is usually exactly what lecture notes and published deck archives are for.
+Strengths
- ✓Open ISO standard, no vendor lock-in
- ✓Native to LibreOffice Impress
- ✓Same machine-friendly zip+XML
!Limitations
- −Text export drops layout and media
- −Fewer third-party readers than PPTX
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
Why convert ODP to GZ?
Converting makes sense where the strengths of GZ meet what ODP cannot give you. Everywhere on Linux and macOS Meanwhile Text export drops layout and media One pass through the converter above puts your file on the right side of that trade-off.
Frequently asked questions
Is this ODP 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 ODP 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 ODP file.
Are the files inside my ODP archive modified?
No. Contents are unpacked in memory and repacked into GZ byte-for-byte — the conversion changes the container, never the files inside it.
