SSA to GZ Converter
Processing entirely on your device — large files may take a moment.
Unpack a .gz into a normal file or repack it as ZIP/TAR when the receiving tool does not understand gzip. If your files are still in SSA format, this page is the shortcut: SSA (SubStation Alpha v4) is the parent format of ASS — the same [Events] Dialogue structure with slightly fewer style fields. Every ASS parser reads SSA files.
iLoveConverter processes everything locally on your computer, which makes it private and fast: no upload wait, no server storage, no limits. Add as many files as you like — batch conversion is built in.

About the SSA format
ASS (Advanced SubStation Alpha) is the subtitle format of the fansubbing world, descended from SSA. Where SRT holds plain text, ASS holds a full styling script: fonts, sizes, colors, outlines, exact positioning, rotation, fade-in effects and even karaoke timing — everything a subtitle needs to look designed rather than typed.
That power is also its portability problem: players that don't implement the renderer show ASS subtitles stripped to bare text, or not at all. Converting ASS to SRT keeps every line and timestamp while deliberately discarding the styling — the right trade for devices that only speak plain subtitles.
+Strengths
- ✓Full styling: fonts, colors, positioning, effects
- ✓The fansub standard — huge library of styled subs
- ✓Karaoke and advanced timing effects
!Limitations
- −Rendering support varies wildly across players
- −Conversion to plain formats discards styling
- −Verbose text format
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 SSA to GZ?
Think of it as moving your file to the container that fits the job. Rendering support varies wildly across players GZ works differently: Everywhere on Linux and macOS If any of that sounds like your task, run the conversion — it takes seconds and nothing leaves your device.
Frequently asked questions
Is this SSA 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 SSA 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 SSA 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.
