App Size

While Tauri by default provides very small binaries it doesn’t hurt to push the limits a bit, so here are some tips and tricks for reaching optimal results.

Cargo Configuration

One of the simplest frontend agnostic size improvements you can do to your project is adding a Cargo profile to it.

Dependent on whether you use the stable or nightly Rust toolchain the options available to you differ a bit. It’s recommended you stick to the stable toolchain unless you’re an advanced user.

incremental = true # Compile your binary in smaller steps.
codegen-units = 1 # Allows LLVM to perform better optimization.
lto = true # Enables link-time-optimizations.
opt-level = "s" # Prioritizes small binary size. Use `3` if you prefer speed.
panic = "abort" # Higher performance by disabling panic handlers.
strip = true # Ensures debug symbols are removed.


  • incremental: Compile your binary in smaller steps.
  • codegen-units: Speeds up compile times at the cost of compile time optimizations.
  • lto: Enables link time optimizations.
  • opt-level: Determines the focus of the compiler. Use 3 to optimize performance, z to optimize for size, and s for something in-between.
  • panic: Reduce size by removing panic unwinding.
  • strip: Strip either symbols or debuginfo from a binary.
  • rpath: Assists in finding the dynamic libraries the binary requires by hard coding information into the binary.
  • trim-paths: Removes potentially privileged information from binaries.
  • rustflags: Sets Rust compiler flags on a profile by profile basis.
    • -Cdebuginfo=0: Whether debuginfo symbols should be included in the build.
    • -Zthreads=8: Increases the number of threads used during compilation.
