Hi Atul thanks for commenting in our community! Lucidchart doesn't have a webpage importer but you can copy/paste any webpage to your document. You can then adjust the size of an embedded link thumbnail by selecting the shape’s edge and dragging to resize. You can also use the resize function to adjust how the thumbnail’s image is cropped.

To access more thumbnail options in Lucidchart select a thumbnail to open the embedded link block panel to the right of the workspace. In Lucidspark select the thumbnail to open the shape’s context menu. Keep in mind some of these options may appear on the embedded link thumbnail itself.

Depending on the type of content embedded you may see these additional options: 

• Expand the embedded link within the document or board to view and edit


• Open the embedded link in a new tab


• Refresh the thumbnail


• Manually choose an image to display on the thumbnail


• Extract a thumbnail’s image to use as a shape on the canvas


• Copy the source link in the embedded thumbnail

Hope this helps! Let me know if you have any other questions.
