The Lumo app: a batch of images prepared together, with results and an Export action.

Beautiful images.
Less waiting.

Photos often contain far more detail than a website needs. That makes them heavier to download. Lumo makes the files smaller, so your images load faster.

One image, prepared with Lumo’s default settings. Both files are 1536 × 1024 pixels, shown here as smaller previews. Results vary by image.

A whole batch.
Three simple moves.

  1. Bring the
    whole batch.

    Drop your images or open a folder. Processing stays on your device, and your originals stay untouched.

  2. Good defaults.
    Already in place.

    Use the defaults or adjust size and quality, then choose Process. Lumo prepares the batch for you.
