TAR → GZ

Learn about the formats: What is TAR? What is GZ?

Convert your TAR archives into GZ files effortlessly to improve compression efficiency. This tool is essential for developers and system administrators who need to optimize storage for Linux-based distributions.

A TAR file is a 'tape archive' that bundles multiple files into one without inherent compression. Converting it to GZ (Gzip) applies the DEFLATE algorithm to that bundle, effectively reducing the overall footprint of the archive. This process wraps the existing TAR structure into a compressed GZ container, making it standard practice for software distribution and backups.

The conversion is strictly lossless. Because both formats are archive-based, your data remains intact, and the file structure is preserved perfectly during the transition.

Tips

Common use cases

Why ConvertX stays free — forever

We built this project so anyone can convert files without paywalls, accounts, or hidden limits. Here is what that promise means in practice.

🎁

Free tools today — and always

Every converter on ConvertX is free to use: no trials, no premium tiers, and no credit packs. We will never put core conversion features behind a subscription. Whether you convert one photo or a hundred files a week, the price stays zero.

🔒

Privacy-first processing

Many image, audio, and video conversions run entirely in your browser. Your files never leave your device for those jobs. When server processing is required for documents or specialized formats, uploads are handled securely and removed automatically — typically within one hour.

🗜️

Archives

Compressed bundles of files and folders.

Common extensions: ZIP, 7Z, RAR, CAB, ARJ

Advantages
  • + ZIP opens natively on most operating systems
  • + 7Z achieves very high compression ratios
  • + Archives simplify bulk downloads and email attachments
Disadvantages
  • Password-protected archives need the correct password
  • RAR may require extra software on some systems
  • Corrupted archives cannot be fully recovered
🖼️

Images

Raster and vector graphics for web, print, and photography.

Common extensions: PNG, JPG, WebP, AVIF, GIF, SVG, HEIC, TIFF

Advantages
  • + WebP and AVIF offer excellent compression for the web
  • + PNG keeps transparency and sharp edges
  • + SVG scales without quality loss
Disadvantages
  • RAW and TIFF files are large and slow to share
  • JPEG loses quality on every re-save
  • Some formats are not supported in older browsers
📄

Documents

Office files, PDFs, ebooks, and plain text.

Common extensions: PDF, DOCX, XLSX, PPTX, ODT, EPUB, TXT

Advantages
  • + PDF locks layout for printing and sharing
  • + DOCX and ODT are easy to edit collaboratively
  • + Plain text works on any device
Disadvantages
  • PDF is hard to edit without special tools
  • Complex layouts may shift after conversion
  • Scanned PDFs need OCR for editable text
🎬

Video

Clips, streams, screen recordings, and movies.

Common extensions: MP4, WebM, MOV, MKV, AVI, MPEG

Advantages
  • + MP4 (H.264/H.265) plays almost everywhere
  • + WebM is efficient for web embedding

Disadvantages
  • High-resolution video needs lots of storage and bandwidth
  • Re-encoding always takes time and may reduce quality
  • Some codecs require licensing for commercial use

Frequently asked questions

No, the files remain identical. The process simply applies compression to the existing TAR archive.
Since TAR is just a container, applying GZ compression will reduce the size, but the impact depends on the compressibility of the files inside the archive.
