ICO to TAR Converter
Processing entirely on your device — large files may take a moment.
TAR preserves the exact file tree and permissions that Linux tooling expects. If your files are still in ICO format, this page is the shortcut: ICO is the Windows icon format. A single ICO file can bundle several sizes (16×16 up to 256×256) of the same icon, used for shortcuts, application icons and website favicons.
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.
How ICO compares to TAR
| ICO | TAR | |
|---|---|---|
| Compression | BMP members, PNG for large sizes | None (pair with gzip/zstd) |
| Best for | Favicons and Windows app icons | Linux packaging and source trees |

About the ICO format
ICO is the Windows icon container, and one of the oldest formats still in daily use. A single ICO file bundles several renderings of the same icon — 16×16, 32×32, 48×48 up to 256×256 — so Windows can pick the right sharpness for shortcuts, Explorer views and taskbars. Each member is stored as classic BMP data or, for large sizes, PNG compression.
On the web, favicon.ico at the site root remains the one icon request every browser makes automatically, which keeps the format alive despite cleaner alternatives like PNG and SVG icons. Keep ICOs small: every visitor downloads one.
+Strengths
- ✓Multiple sizes bundled in one file
- ✓Every browser falls back to /favicon.ico automatically
- ✓Deep Windows integration for app icons
!Limitations
- −Practical size ceiling around 256×256
- −Windows-centric; little use outside icons
- −Quality is frozen at export time
About the TAR format
TAR (tape archive) is Unix's fifty-year-old answer to bundling: it concatenates files with headers into a single stream, preserving POSIX permissions, ownership and symlinks — but compressing nothing. It is the container half of the classic .tar.gz pairing and the native format of Linux source trees and backups.
Being pure bundling, TAR pairs with a compressor: gzip (the classic), bzip2, zstd. Alone, a TAR is the same size as its contents. Windows 10+ ships bsdtar, so even Windows can unpack it now — permissions aside, where NTFS has no room to be faithful.
+Strengths
- ✓Preserves Unix permissions and symlinks
- ✓Streamable: works over pipes and tapes
- ✓The standard of Linux distribution and backup
!Limitations
- −No compression by itself
- −No built-in encryption
- −Permissions meaningless on Windows filesystems

Frequently asked questions
Is this ICO to TAR 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.
Will I lose quality converting ICO to TAR?
No — TAR is a lossless format, so every pixel of the converted image matches your original ICO file. You can also adjust the quality/size balance before converting when the target format supports compression.
What happens to EXIF data and other metadata?
Conversions here re-encode the image, and re-encoding generally does not carry the original metadata over. If the EXIF data of your ICO files matters (camera model, GPS, timestamps), keep the original file as the master and treat the converted copy as the shareable version.
Can I convert several ICO files at once?
Yes — drop as many files as you like into the tool and they are converted in one batch. When more than one file comes out, everything is bundled into a ZIP for a single download.
