<h2 id="editing"><a href="#editing">Editing your picture before upload</a></h2>
<p>Most editors degrade picture quality, making pictures less accurate <b>and</b> bigger in file size. If you need to edit a picture before upload, please try to only use <a href="https://github.com/lossless-jpg/data#readme">lossless JPEG editors</a>:</p>
<ul>
<li>
<b>Rotate a picture losslessly:</b>
Use <a href="https://play.google.com/store/apps/details?id=jp.kame.jpegcropper">JPEG Cropper</a> (or the gallery's built-in rotation tool if you have a Samsung phone).
</li>
<li>
<b>Crop a picture losslessly</b>:
Use <a href="https://play.google.com/store/apps/details?id=jp.kame.jpegcropper">JPEG Cropper</a>. Alternatively, you can upload first and then crop with <a href="https://croptool.toolforge.org">Croptool</a>.
</li>
<li>
<b>Blur people's faces or car plates for privacy reasons, without degrading the quality of the rest of the picture:</b>
The only lossless Android app that offers this feature is <a href="https://play.google.com/store/apps/details?id=jp.kame.ajt">AJT</a>, not user-friendly but it does the job:
<ol>
<li><a href="https://play.google.com/store/apps/details?id=jp.kame.ajt">Install AJT</a>, open it.</li>
<li>Tap <b>Input</b>, select your picture.</li>
<li>Tap <b>Switch</b> then <b>Transform</b> then <b>TransformType</b> then select <b>-pixelize</b>.</li>
<li>Tap <b>Area Selector</b> then select one area to blur (you have to drag the edges of the white-bordered rectangle, which are initially at the edges of the picture, you might have to zoom out first).</li>
<li>Tap <b>Execute</b>, the modified picture should be in your gallery near the original, with an _ajt suffix.</li>
</ol>
</li>
</ul>
<p>Between taking a picture and uploading it, please do not apply color filters, flip horizontally/vertically, add stickers/text, nor apply any restoration/AI/upscaling. Such operations lose original data. If you really want to apply such transformations, please upload the original first, then upload the transformed picture as a new version using <a href="commons.wikimedia.org">the desktop website</a>.</p>

<p><a href="https://play.google.com/store/apps/details?id=jp.kame.jpegcropper">JPEG Cropper</a> allows lossless rotation, lossless cropping, and even lets you blur parts of a picture without recompressing the surrounding areas.</p>

<p>Nearby is a fantastic way to find interesting places. But imagine that go to the place pinned on the map, and it is not at all what was expected? In such cases, fixing the problem is very important, and you can do it easily! It will benefit not only Commons but also all other Wikimedia projects and in particular Wikipedia. Here is how to proceed:</p>

<p><b>Scenario</b>: Yes there used to be a castle here, but now there is absolutely nothing left, maybe it is just green fields or a factory or recent houses. There is not even a plaque indicating that there used to be a castle.</p>
