Tessera v1.0.11

Tessera is a standalone Windows app for preparing pixel art and icons.
It began as a way to correct uneven grids and inconsistent pixel sizes in AI-generated pixel art.

Change size and colors independently or together, align grids, reduce cells to single pixels and keep result histories. Create multi-size ICO files, or remove a solid background in its own workspace and save a full-size transparent PNG. Choose any library source or saved result from the From editor thumbnail panel. Background removal works globally or from connected image edges, with adjustable tolerance.

Convert supported Aseprite animations in batches to PNG sprite sheets with JSON frame timings. All processing runs locally.

What's new:

• Check for newer GitHub releases automatically at startup, or manually from the bottom bar and File menu.
• Confirm an update to download the desktop executable, verify its SHA-256 checksum, replace the installed file and restart. The image library stays in place.
• Continue working offline when update checks are unavailable. Automatic installation requires the published Tessera.exe in a writable folder; development builds open the release page instead.

Updating from v1.0.10 or earlier: download this release manually once to enable future in-app updates.

The CLI includes resize, colors, aseprite, align, reduce-grid, ico and remove-background commands for scripted workflows. Use reduce-grid (also available as compact-grid) to turn uniform aligned cells into individual pixels.

Download Tessera.exe or Tessera-win-x64.zip for the desktop app, or Tessera-cli-win-x64.zip for the CLI. No .NET installation is required. SHA256SUMS.txt contains the download checksums.

Previously named Pixelizator. The library is now stored at %LOCALAPPDATA%\Tessera\Library. On first launch, the old Pixelizator library is copied into it and retained as a backup. The application interface currently uses Russian labels.
