How it works

  1. Choose your settings

    Adjust quality or target file size, set a maximum dimension, and select an output format.

  2. Add images

    Drop files into the tool, paste an image, or choose files from your device.

  3. Review and save

    Check the result, then download files individually or as a ZIP archive.

Supported formats

MEZENCORE accepts JPEG, PNG, WebP, HEIC/HEIF, AVIF, GIF, SVG, JXL, ICO, and TIFF. You can export as JPG, PNG, WebP, or ICO.

HEIC/HEIF, ICO, and TIFF use included decoders; JPEG, PNG, WebP, GIF, AVIF, SVG, and JXL rely on browser image support.

For example, a transparent shop logo usually needs PNG or WebP, while a phone photo for a message may be better as JPG. Compare the downloaded result at its intended size; text edges and transparency can make one format a poor fit even when its file is smaller.
