Open tool →How private image processing works
JPG, PNG, and WebP tools use browser image APIs on your device. UnitConverterHQ does not receive or store the selected image. HEIC requires a dedicated client-side decoder because browsers do not expose the same native HEIC decoding path as common web formats.
Safe processing limits
This first release accepts one image at a time, up to 40 MB and 30 megapixels. These limits reduce the risk of a browser tab running out of memory on phones and lower-powered devices.
