Notion page cover images display at approximately 1500 pixels wide on desktop. For the best cover image display, upload at 1500x600 or wider. Notion will crop to fit the cover area, and you can adjust the vertical position.
Inline images in Notion pages display at the page content width, which is approximately 708 pixels for standard width and up to 900 pixels for full width pages. Uploading images at these widths ensures sharp display without unnecessary file size.
With ImgTools, resize your Notion images to the appropriate dimensions. For covers, use 1500x600. For inline content, resize to 800-900px wide.
Save as JPEG at 80-85% quality for photographs or PNG for screenshots and diagrams.
