How it works

Upload your photo

Drop your image into EditThisPic. JPG, PNG, WebP up to 7MB. Use a photo with good subject placement and clean edges for best extension results.

Expect: Simple edits like color enhancement: 15-30 seconds. Background extensions: may need 2-3 refinements for seamless edges.
Describe what you want

Type your instruction clearly: 'extend the background on both sides to make it wider' or 'remove the stranger on the left and fill with beach.' Be specific about what to extend or remove. No marking required.

Tip: Mention the style you want: 'extend with matching sky gradient' or 'fill with similar blurred greenery' for seamless results.

Copy one of these to get started:

Photo too narrow for cover extend the background on both sides to make this photo wider, matching the existing colors and style
Try This →

Unwanted person in frame remove the person on the right side and fill with the natural background
Try This →

Dull or flat colors enhance the colors to make them more vibrant and eye-catching, boost the contrast slightly
Try This →

Boring sky in landscape replace the sky with a dramatic sunset gradient in orange and pink tones
Try This →

2 more prompts

Need more headroom above subject extend the top of the image with more sky to give more space above the subject
Try This →

Clean up distracting elements remove the distracting elements in the background and replace with clean, blurred scenery
Try This →
Generate and review

Check that extended areas blend naturally with the original. Look for color consistency at the seams and ensure your subject remains sharp and well-positioned.
Refine with markers if needed

If the extension shows visible seams or the AI filled the wrong area, tap markers on those spots and regenerate. Most cover edits work without markers.

Tip: Markers are for precision refinement, not a required step. Try without them first.

"Finally got a cover photo that doesn't cut off my head. Just told it to extend the sky and it worked perfectly." @socialjen

Portrait extended for cover dimensions

A vertical portrait needed to become a horizontal cover. The AI extended the beach background on both sides seamlessly.

Prompt: extend the background on both sides with more beach and ocean to make this wider for a Facebook cover

Washed out sunset mountain photo — Before

Vibrant sunset with enhanced orange and pink colors — After

Colors enhanced for impact

A sunset photo looked washed out. Color enhancement made it pop as a striking cover photo.

Prompt: enhance the colors to make the sunset more vibrant with deeper oranges and pinks, increase contrast for impact

If something looks off

Extended area looks different from original

Why: The AI generated content that doesn't match the lighting, color, or texture of the original edges.

Try: extend the background with the exact same color tone and lighting as the original photo, seamless transition

Try This →

Tip: Mention specific colors: 'extend with the same warm golden tones' for better matching.

Visible seam where extension meets original

Why: The transition between original and generated content is too abrupt.

Try: blend the edges more smoothly where the extension meets the original, no visible seam

Try This →

Tip: Tap markers directly on the seam line and ask to blend that specific area.

AI changed the wrong area or something I didn't want changed

Why: The AI couldn't determine exactly which area you meant from description alone. This happens with ambiguous requests.

Try: Tap a marker on the specific area you want to change, then regenerate with the same prompt

Try This →

Tip: Markers tell the AI 'I mean THIS one specifically.' Use them when description alone is ambiguous.

Subject looks distorted after edit

Why: The AI accidentally modified your main subject while editing the background.

Try: keep the main subject exactly as is, only modify the background areas

Try This →

Tip: Be explicit about what to preserve: 'keep the person unchanged, only extend the scenery.'

Quick answers

Do I need to mark the background before extending it?

No! Just describe what you want: 'extend the background on both sides' or 'add more sky at the top.' The AI understands these concepts. Only use markers when you need precision, like specifying which side to extend or refining a seam.

What dimensions work best for Facebook cover photos?

Facebook cover photos display at 820x312 pixels on desktop and 640x360 on mobile. EditThisPic can extend any photo to fit these dimensions. Start with a photo wider than it is tall for best results.

Can I extend a photo in only one direction?

Yes. Specify the direction: 'extend the left side with more trees' or 'add more sky at the top.' The AI will only generate new content in that area.

How do I make sure my face doesn't get cut off on mobile?

Position your subject slightly lower in the frame. Facebook crops the top and bottom on mobile. After extending, check that important elements are in the center third of the image.
