How it works

  1. Upload your blog image

    Drop the photo you want to use as a featured image or thumbnail. Works with photos from stock sites, your own photos, or screenshots. Best results when the main subject is clear and the element you want to change is identifiable.

    Expect: Blog image edits typically process in 15-25 seconds. Background replacements may take up to 35 seconds.
  2. Describe what to change

    Type exactly what you want: 'remove the cluttered background and replace with a clean white studio look', 'remove the person on the right', 'make the background blurred and bokeh to focus on the subject', 'replace the dull grey sky with a bright clear blue'. No selection tools, no layer masks — just describe it.

    Tip: For blog thumbnails, clean and uncluttered backgrounds help the image work at small sizes. Describe a simple, complementary background.

    Copy one of these to get started:

    Remove busy background replace the busy street background with a clean, slightly blurred neutral background that doesn't distract from the subject
    Remove unwanted person from stock photo remove the person on the right side of the image and fill naturally with the background
    Swap dull background for vibrant one replace the plain white background with a soft gradient from pale blue to white that feels light and airy
    Brighten a dark or underexposed photo brighten this photo, increase the overall exposure and lift the shadows to make it feel vibrant
    2 more prompts
    Remove distracting object from scene remove the bright red trash can at the bottom right of the frame and fill with the floor
    Add subtle background blur add a soft bokeh blur to the background to make the foreground subject stand out more
  3. Check it works at thumbnail size

    After editing, mentally preview the image at blog card size (typically 300-400px wide). A clean background and clear subject communicate faster at small sizes. Check that the main subject is still clear.

Busy background replaced with clean backdrop

A photo taken in a cluttered space — fine for personal use, but not ideal as a blog featured image. Background replacement turns it into a clean, professional thumbnail.

Prompt: replace the busy cluttered office background with a soft blurred light grey background that focuses on the subject

Unwanted object removed from stock photo

A stock photo was almost right except for an unwanted element. Removing it saves buying a different photo.

Prompt: remove the bright yellow bag at the left edge of the frame and fill with the natural scene background
