Inkscape

How can I use Inkscape to reduce the file size of an image?

Asked by David Caverly

I have a tif file that is unnecessarily large and need to send via email. I don't see any functionality in the Inkscape program that will allow me to reduce image quality, detail and file size. In Photoshop I would use the "image size" menu item & window to change the image resolution, and/or change the file type (e.g. from tif to gif or jpg) to one which results in a smaller size file. How can I do this in Inkscape? (I see how to save the file in a different file format, but don't see gif as an option. I re-saved a tif file as a png file to see if it would help with file size but according to Mac Finder the file size did not change at all.

Thanks,
David

inkscape preferably deals with vector imaging, to reduce file size,
 an only option is adjusting with object handles, or minimise added features ,
if that could be 'editable',
further save with anew file name or extension .

Inkscape is a vector graphics editor, not an image editor. For what you're trying to do, use GIMP instead. To do this:

1. Open your TIFF image in GIMP.
2. Resize the image, using Image > Scale Image, and enter your desired image size.
3. File > Export. Type your filename with the extension for your desired output format (e.g. "image.jpg"), and press Export. It will then prompt you for quality settings.

GIF will almost always produce a larger file than PNG at the same quality settings. JPEG is lossy so it can be much smaller than PNG.

I strongly disagree with the above answer. Yes Inkscape is a vector graphics editor, but we create things in Inkscape to use them in the real world, e.g. in pdf format.

It is a great thing that the original size of an image is maintained while working with it, however, when exporting to pdf it should be possible to manipulate the dpi of images.

Can you help with this problem?
