How It Works

Add multiple images via drag & drop or the file picker. Choose your target format, quality, and optional maximum dimensions. Click "Convert All" to process everything locally in your browser using the Canvas API.

Supported Formats:

  • PNG — Lossless, transparency supported
  • JPEG — Lossy, smallest file size for photos
  • WebP — Modern format, excellent compression
  • AVIF — Next-gen format (requires browser support: Chrome 85+, Firefox 93+)
  • BMP — Uncompressed bitmap
  • TIFF — Uncompressed, generated via custom encoder

Batch Processing: All files are converted sequentially to avoid memory issues. Progress is shown per file. Results can be downloaded individually or as a ZIP archive.
