How do you change your company logo in top left of page inside of salesforce?
First you need to upload your logo to SF. Go to the Documents tab, and upload your logo here.
Consider these requirements when choosing a custom app logo from the document library:
- The image must be in GIF or JPEG format and less than 20 KB in size.
- If the image is larger than 300 pixels wide by 55 pixels high, then it will be scaled to fit.
- For the best on-screen display, we recommend you use an image with a transparent background.
- The Externally Available checkbox must be selected on the document's properties so that users can view the image.
Second, go to Setup > Create > Apps > click on the app name > click Edit > Choose the Image Source for the Custom App Logo
