<title>Convert to a different file type</title>
<p>Pictures are saved in a specific file format, like JPEG or PNG. You can
convert from one file format to another.</p>
<section id="single">
<title>Convert a single picture to a different file type</title>
<list type="numbered">
<item>
<p>Click <guiseq><gui>Image</gui><gui>Save As</gui></guiseq>. The
<gui>Save Image</gui> window will pop up.</p>
</item>
<item>
<p>In the name field, change the <em>file extension</em> to the file type you want to
convert your image to. The file extension is the part of the file name after the period.</p>
<p>For example, to convert a JPEG (<file>.jpg</file>) file into a Bitmap file (<file>.bmp</file>):</p>
<p><em>original file:</em> <file>image.jpg</file></p>
<p><em>new file:</em> <file>image.bmp</file></p>
</item>
<item>
<p>Click <gui>Save</gui>, and a new file will be saved in the new format. The old file (in the old format) will remain where it was, and will not be deleted.</p>
</item>
<item>
<p>The image viewer will ask if you would like to reload
the new picture. Click <gui>Reload</gui> to do this, or click
<gui>Hide</gui> if you want to continue working with the
original file.</p></item>
</list>
<p>The image viewer tries to guess which file format to save a picture in
based on the file extension you choose. If it doesn't recognize the file
extension you type, or if you don't know which one to use, click
<gui>Browse</gui> in the <gui>Save Image</gui> window. This will allow you to
choose the file type from the drop down box.
</p>
</section>
<section id="multiple">
<title>Convert multiple pictures to a different format</title>
<p>You can convert a number of pictures from one file format to another in
one go. This is useful if you have a lot of pictures that need converting.</p>
<list style="numbered">
<item>
<p>In the <link xref="view#image-gallery">image gallery</link>, press and
hold down the <key>Ctrl</key> key and select the pictures you want
to convert one by one. Alternatively, press
<keyseq><key>Ctrl</key><key>A</key></keyseq> to select all of the pictures.</p>
</item>
<item>
<p>Click <guiseq><gui>Image</gui><gui>Save as</gui></guiseq>. A window
will appear (shown below).</p>
<media type="image" src="figures/multiple-convert.png" width="300"/>
</item>
<item>
<p>The converted pictures will be saved in the current folder by default.
If you want to save them elsewhere, change the <gui>Destination folder</gui>.</p>
</item>
<item>
<p>Select the file format you want to convert the pictures to from the
drop-down list to the right of the <gui>Filename format</gui> box.</p>
</item>
<item>
<p>Click <gui>Save</gui>.</p>
