Batch Convert to Compressed File

A cross-platform desktop utility for batch compressing files into individual .7z or .zip archives and verifying the integrity of existing .7z, .zip, and .rar archives.

Built with Avalonia 12, .NET 10, and SharpCompress. Runs on Windows, Linux, and macOS on both x64 and arm64.

Features

• Batch compression — one archive per file, .7z (LZMA2) or .zip (Deflate)
• Archive verification — .7z, .zip, and .rar, with full size and CRC-32 checks
• Flexible file management — optionally delete originals after compression, or move verified and failed archives into separate folders while preserving subfolders
• Live feedback — progress bar, current file, elapsed time, write speed, and total/success/ failed/skipped statistics
• Live log on the right — resizable activity log powered by Serilog
• Professional black/indigo theme — tooltips on every control
• About window — version, platform, runtime, and project links
• GitHub update check — offers to open the download page when a newer release exists
• Donation banner — disappears permanently only after a donation is verified by the API
• Startup statistics — anonymous application ID and version sent to the stats endpoint
• Automatic bug reports — every Warning+ Serilog event is forwarded to the bug report API
• Fully managed archive engine — no native 7-Zip binaries on any platform

Downloads

Pick the asset for your platform from the latest release:

Platform	x64	arm64
Windows	BatchConvertToCompressedFile_<version>_win-x64.zip	BatchConvertToCompressedFile_<version>_win-arm64.zip
Linux	BatchConvertToCompressedFile_<version>_linux-x64.tar.gz	BatchConvertToCompressedFile_<version>_linux-arm64.tar.gz
macOS	BatchConvertToCompressedFile_<version>_osx-x64.tar.gz	BatchConvertToCompressedFile_<version>_osx-arm64.tar.gz

Each bundle contains the application, LICENSE, ReadMe.md, and WhatsNew.md. The release also publishes checksums.txt with SHA-256 hashes.

Requirements

• Releases: framework-dependent single-file build — install the .NET 10 runtime for your platform. The .NET runtime is intentionally not embedded in the executable.
• From source: .NET 10 SDK
• Linux/macOS: a graphical desktop session (X11, Wayland, or Aqua)

Usage

Compress files

1. Open the Compress Files tab.
2. Select a source folder and an output folder (they must be different).
3. Choose .7z or .zip.
4. Optionally enable deletion of originals after successful compression.
5. Click Start compression.

Existing archives are skipped and never overwritten. Files with duplicate base names are written as name.zip, name (2).zip, and so on.

Verify archives

1. Open the Verify Archives tab.
2. Select the archives folder.
3. Optionally enable subfolder scanning and success/failed move folders.
4. Click Start verification.

Every entry is fully decompressed and checked against its stored size and CRC-32.

Build and test

dotnet restore CSharp_BatchConvertToCompressedFile.sln
dotnet build   CSharp_BatchConvertToCompressedFile.sln -c Release
dotnet test    CSharp_BatchConvertToCompressedFile.sln -c Release

Run:

dotnet run --project BatchConvertToCompressedFile

Publish a framework-dependent single-file bundle for any RID:

dotnet publish BatchConvertToCompressedFile -c Release -r linux-arm64 --self-contained false `
  -p:PublishSingleFile=true -p:IncludeNativeLibrariesForSelfExtract=true -p:DebugType=embedded `
  -o artifacts/linux-arm64

Supported RIDs: win-x64, win-arm64, linux-x64, linux-arm64, osx-x64, osx-arm64.
