## Direct answer

ImgTurbo decodes, transforms and encodes one supported image in the visitor's
browser. The image is not posted to ImgTurbo. It always requests JPEG and PNG
output and offers WebP only when the browser reports WebP encoding support.

## Actual capabilities

- Input: one JPEG, PNG or WebP that the browser can decode.
- Limits: 30 MB file, 40 megapixels, 16,384 pixels per side.
- Output: JPEG, PNG and browser-supported WebP.
- Transforms: percentage/dimension resize, 90-degree rotation, horizontal or
  vertical flip, grayscale, and a chosen JPEG transparency background.
- Result: measured media type, bytes, dimensions and size difference.
- Free, no account and no watermark.

## Important limitations

- No batch, GIF, BMP, TIFF, ICO, SVG, HEIC, RAW, AVIF or PDF conversion.
- Animated input becomes a still image; animation is not preserved.
- Canvas re-encoding normally omits source EXIF, GPS and other metadata.
- Conversion does not guarantee a smaller file or better visual quality.
- Browser codecs and output bytes vary.

## Privacy boundary

Image bytes and settings stay in the browser. Google Analytics loads only after
consent and does not receive them. Ordinary HTTP delivery/security logs can
contain request metadata, but the converter makes no image-upload request.
