JPEG-first compression for camera and download folders

JPEG still dominates cameras, scanners, and marketplace exports. This jpg compressor and jpeg compressor tune quality in the browser so you get smaller files without a desktop suite. Prefer desktop image compression on compress image Windows PCs, compress image Mac laptops, and compress image Linux workstations? Same WASM path everywhere. If your phone shot HEIC, convert with HEIC to JPG first, then compress — that is the honest Apple pipeline before JPEG output.

How it works

  1. 1

    Upload a JPG or JPEG

    Drop a .jpg/.jpeg into the jpeg compressor. For iPhone HEIC, convert HEIC to JPG first, then continue with the jpg compressor.

  2. 2

    Adjust quality locally

    Desktop image compression happens in Wasm — compress image Windows, Mac, or Linux sessions stay private on your machine.

  3. 3

    Download the smaller JPEG

    Export and reuse for web, email, or chat. Crop or resize first if framing matters more than megapixels.
