Upload your file

Drag and drop, click to browse, or paste a URL. Batches take up to 20 files at once - 230+ input formats across video, audio, image, document, and archive types.

02

Choose an output format

Pick from over a hundred output formats. Filter by category or search by name - every option is open to everyone, no account needed.

03

Convert & download

Hit Convert and grab your download link moments later. Originals are erased when the job completes; results are cleared within about an hour.

What is an LZMA file?

The LZMA (Lempel-Ziv-Markov chain Algorithm) format is a lossless data compression algorithm and file format developed by Igor Pavlov and first featured in the 7-Zip archiver in 1998. It utilizes a dictionary compression scheme somewhat similar to LZ77 but with significant improvements via a range encoder and complex probability models, resulting in high compression ratios comparable to PPM (Prediction by Partial Matching). The raw .lzma stream format typically includes a 13-byte header defining properties like dictionary size (up to 4 GB) and uncompressed size, often used within .7z or .xz containers rather than as standalone files.

How to open an LZMA file

LZMA files are natively supported on Linux distributions via the lzma command-line utility or the xz-utils package. On Windows and macOS, native support is absent, requiring third-party archival software. 7-Zip is the primary reference implementation for decoding LZMA streams on Windows; alternatively, multi-format extractors like PeaZip or The Unarchiver (macOS) utilize the LZMA SDK to decompress the data.

What is a TAR file?

The TAR (Tape Archive) format is a file format standardized by POSIX.1-1988 and later POSIX.1-2001 (pax), originally developed for writing data to sequential I/O devices like magnetic tape drives. Unlike modern archive formats, TAR is purely a container format that concatenates multiple files into a single archive without native compression, preserving file system attributes such as user/group permissions, dates, and directory structures. It is frequently paired with compression utilities like Gzip or Bzip2 in Unix-like environments.

How to open a TAR file

Most Unix-based systems (Linux, macOS, BSD) include native support via the GNU Tar command-line utility. Windows does not natively support TAR extraction in versions prior to Windows 10 (Build 17063), requiring third-party tools. For cross-platform compatibility, 7-Zip and WinRAR are standard utilities for inspecting and extracting TAR containers.

Developer API

Convert LZMA to TAR via API

Automate LZMA to TAR conversions in three steps: create a job, upload your file, then poll for the result.

# 1. Create job
curl -X POST https://api.runconvert.com/v3/jobs \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "tag": "lzma-to-tar",
    "tasks": {
      "upload-file": {
        "operation": "import/upload"
      },
      "convert": {
        "operation": "convert",
        "input": "upload-file",
        "output_format": "tar"
      },
      "export-result": {
        "operation": "export/url",
        "input": "convert"
      }
    }
  }'

# 2. Upload your file (use upload_url from the response)
curl -X PUT "$UPLOAD_URL" --upload-file input.lzma

# 3. Poll for result
curl https://api.runconvert.com/v3/jobs/$JOB_ID?include=tasks \
  -H "Authorization: Bearer YOUR_API_KEY"
