Best practices for better results

Image optimization works best when you choose the right balance between file size, visual quality, dimensions, format compatibility and privacy. These tips help you get a cleaner result.

  • Start from the original image whenever possible.
  • Review the output before publishing or deleting your original file.
  • Use related tools like resize, convert or metadata removal when you need a more specific result.
  • Choose the right format for the job: JPEG for photos, PNG for sharp graphics and WebP for modern websites.

Create a blank image at any size

An empty image is a simple blank canvas saved as a real image file. It can be fully transparent, filled with a solid colour, or exported as PNG, JPG or WebP. Designers use blank images for mockups and backgrounds. Developers use them as placeholders and test files. Content creators use them as starting canvases for social posts, thumbnails and layouts.

Common blank image sizes

Use Size
Open Graph / social share image 1200 × 630
Square social post 1080 × 1080
Vertical story or mobile canvas 1080 × 1920
YouTube thumbnail 1280 × 720
HD background 1920 × 1080
Simple placeholder 400 × 400

Transparent PNG, solid JPG or WebP

Use PNG or WebP when you need transparency. Use JPG only when the image is filled with a solid colour, because JPEG does not support transparent pixels. If you choose transparency and JPG together, the output is automatically flattened to a normal background.

Good to know: a blank transparent image is still a real image file. It has width, height and format, even though it contains no visible content.

What can you use an empty image for?

  • Create placeholder images for websites and app mockups
  • Generate transparent PNG canvases for design work
  • Create solid-colour backgrounds for slides, thumbnails and posts
  • Make test images for upload forms and layout debugging
  • Create blank Open Graph images, square posts and vertical story canvases

Private by design

This tool does not need an upload because there is no source image to upload. The blank image is generated from scratch in your browser using the dimensions and colour you choose.
