View optimized image information and download time
The annotation area below each image in the Save For Web & Devices dialog box provides optimization information.
The annotation for the original image shows the file name and file size. The annotation for the optimized image shows
the current optimization options, the size of the optimized file, and the estimated download time using the selected
modem speed. You can choose a modem speed in the Preview pop-up menu.
Optimize an image for the web
1 Choose File > Save For Web & Devices.
2 Click a tab at the top of the dialog box to select a display option: Optimized, 2-Up, or 4-Up. If you select 4-Up, click
the preview you want to optimize.
3 (Optional) If your image contains multiple slices, select one or more slices you want to optimize.
4 Select a preset optimization setting from the Preset menu, or set individual optimization options. The available
options change depending on the file format you select.
If you’re working in 4-Up mode, choose Repopulate Views from the Optimize menu to automatically generate lower-
quality versions of the image after you change the optimization settings.
5 Fine-tune the optimization settings until you are satisfied with the balance of image quality and file size. If your
image contains multiple slices, be sure to optimize all the slices.
To restore an optimized preview to the original version, select it and then choose Original from the Preset menu.
6 If optimizing an image with an embedded color profile other than sRGB, you should convert the image’s colors to
sRGB before you save the image for use on the web. This insures that the colors you see in the optimized image will
look the same in different web browsers. The Convert to sRGB option is selected by default.
7 (Photoshop only) From the Metadata menu, choose what XMP metadata to save with the optimized file. Metadata
is fully supported by JPEG file format, and partially supported by GIF and PNG file formats. It can include any
metadata file information that was added to the document (choose File > File Info to view or enter document
metadata).
None No metadata saved. Produces the smallest file size.
Copyright Saves copyright notice, rights usage terms, copyright status, and copyright info URL.
Copyright and Contact Info Saves all copyright information, plus the following information: creator, creator job title,
e-mail(s), address, city, state/province, postal code, country, telephone(s), and website(s).
All Except Camera Info Saves all XMP metadata, except EXIF data. EXIF data includes camera settings and scene
information such as shutter speed, date and time, focal length, exposure compensation, metering pattern, and whether
a flash was used.
All Saves all XMP metadata in the file.
8 Click Save.
