If you have a recent version of LibreOffice (4.1 or higher), you’ll have the option to right-click the image you want to compress and choose “Compress Graphic”. A dialog box should appear that will allow you to resize the image to a desired number of pixels/DPI.

If you add images in png or jpeg formats, they will be keep in this format in the ODF file.

Another way to modify an image in Writer: right clic on the picture → Edit with an external tool → do your change → save.

other word, i must edit every pic using external tool to make the pic have small size and weight. to make file writer not have big kb.

I observed that gif-files in size between jpg and png. But I don’t know about image quality when looking at it or printing them.

Unlike its brother from Microsoft, LO is not rude to decide on its own to reduce the size of the image (in quality or dimension) under the assumption that you may need to increase or decrease the file size at a later time (believe me, it happens all the time). This is exactly the same way it is done in professional desktop publishing tools like Adobe Page Maker or Corel Draw. An ODT file is simply a container for storing all the building blocks of the document.

You have two options

  1. If you are sure that you will never need to increase the size or quality or your image, use a batch editor like Google Picasa to change the image file properties (size or quality). Or
  2. If your concern is while having to send the document as an e-mail attachment, send it as a PDF file and while doing so, enable JPEG compression (@ 75%) and reduce the resolution to about 100dpi which is quite good for viewing on screen. In case you want to send editable files, I’d suggest you to force your mind to accept that you will never need to change the image parameters and accept option 1 above :slight_smile:

It is very helpful information.
i was having a problem that my images were very big in size and that complicated my presentation. I used http://compresspic.com, it solved my problem. but images are compressed one by one, i need to do all at a time.
