Create Perfect Facebook Cover Photos
Turn any photo into the perfect cover. No cropping headaches, no design skills needed.
Type 'extend the background to fit cover photo dimensions' or 'remove the person on the right and fill with scenery' and EditThisPic handles the rest in 15-30 seconds. The AI extends edges, removes distractions, and enhances colors automatically. No selection tools needed. Free to try, no account required.
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.
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.
Copy one of these to get started:
extend the background on both sides to make this photo wider, matching the existing colors and style
remove the person on the right side and fill with the natural background
enhance the colors to make them more vibrant and eye-catching, boost the contrast slightly
replace the sky with a dramatic sunset gradient in orange and pink tones
2 more prompts
extend the top of the image with more sky to give more space above the subject
remove the distracting elements in the background and replace with clean, blurred scenery
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.

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

Stranger removed from group photo
A photobomber appeared at the edge of a family beach photo. One prompt removed them and filled with matching sand and ocean.
remove the person on the far right and fill with beach and ocean to match the rest of the scene
Colors enhanced for impact
A sunset photo looked washed out. Color enhancement made it pop as a striking cover photo.

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.
extend the background with the exact same color tone and lighting as the original photo, seamless transition
💡 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.
blend the edges more smoothly where the extension meets the original, no visible seam
💡 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.
Tap a marker on the specific area you want to change, then regenerate with the same prompt
💡 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.
keep the main subject exactly as is, only modify the background areas
💡 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.
