Frequently asked questions

Is my file uploaded?

No. The conversion runs entirely in your browser. The file never leaves your device – there is no server that could see it. Once the page has loaded, the tool even works offline.

In which order are the three settings applied?

Saturation first, in the LCh colour space so that hue and lightness do not shift, then contrast and brightness together as one linear step. Values that fall outside the range are clipped to pure black or white.

Is there a preview?

The result list shows each processed image; adjust the sliders and run again if it is not right yet. Your originals stay untouched, so you can try as often as you like.

Does the file format stay the same?

Yes. A JPG stays a JPG, a PNG stays a PNG, WebP and AVIF likewise. JPG, WebP and AVIF are re-encoded with the quality you set; PNG stays lossless. To change the format, use one of the converters afterwards.

What happens to EXIF data such as camera model or GPS position?

By default we remove all metadata, including GPS coordinates. Switch on “Keep metadata (EXIF)” if you want it kept. The orientation stored in the file is applied to the pixels either way, so the image never appears rotated.
