Why extend here instead of stretching or adding bars

Forcing a 4:5 phone shot into 16:9 distorts faces and shapes; cropping cuts away your subject; adding black bars looks dated. Lumenfix uncrops the image cleanly, preserving your original center and continuing natural lighting and textures.

  1. 01

    The center is locked and untouched

    Every pixel you upload stays exactly where it was. New sky, snow, floor, or environment only appears in the newly expanded border—no face-swapping, no subject hallucinations.

  2. 02

    Physics-consistent light and texture continuity

    The model reads edge details—snow grain, wood grains, sunset angles—and continues them naturally instead of pasting a generic backdrop.

  3. 03

    Presets for every screen and custom frames

    One-click presets for 1:1 avatars, 4:5 vertical feeds, 16:9 desktops, and 9:16 mobile stories, plus freeform drag handles for custom layouts.

  4. 04

    Optional edge prompt guidance

    Add a brief prompt like “clear winter sky” or “wooden deck” to guide complex borders. Leave it blank for automatic scene continuation.

Visual comparisons and real-world outpainting

See how landscape, portrait, ecommerce, and architecture photos look when extended cleanly into wider frames.

Vertical landscape to 16:9 desktop wallpaper

Turn a vertical lake photo into a 16:9 desktop background without losing the pines or squishing the mountain peaks.

  • Portraits that need avatar or cover breathing room

    Leave the face and hair completely untouched while expanding the background for 1:1 profile pictures or 4:5 feed posts.

  • Ecommerce product stills with space for typography

    Push the bottle or box inward to create clean margins for product titles, value props, and pricing badges.

  • Interior and architectural wide-angle expansion

    Open up a tight living room photo into an expansive header banner while preserving realistic perspective and furniture geometry.

  • Anime, illustrations, and digital art uncropping

    Expand borders around artwork for wallpaper or double-page spreads while matching the original linework and brush texture.

  • Travel photography opened into cinematic aspect ratios

    Transform street or beach snapshots into wide cinematic scenes where the horizon and skies continue smoothly.

How to extend an image online

Three quick steps. Your original photo is always the pristine center of the new canvas.

  1. Step 1

    Upload your photo

    Drop in a JPEG, PNG, or WebP up to 20 MB, or paste directly from your clipboard.

  2. Step 2

    Set the target frame

    Choose 1:1, 4:5, 16:9, 9:16, or drag the frame handles. Only the empty outer canvas will be generated.

  3. Step 3

    Generate and download

    Inspect the seamless edge blending against the original photo, then download in full quality.

Extend a photo

Precise canvas and composition controls

A focused darkroom canvas designed to extend existing photos, not a random text-to-image generator.

  • Standard presets and freeform dragging

    Popular aspect ratios in one click, plus pixel-precise custom dimensions for custom print or web specifications.

  • Optional edge hint prompts

    Describe specific peripheral elements or leave it blank when the natural sky, terrain, or room background is already clear.

  • Strictly locked island protection

    The source rectangle is never repainted. If anything inside the original frame looks altered, that is a bug, not a feature.

  • Connected post-processing workflow

    Enhance face details first if your source is soft, or upscale the completed image to 4K / 8K for high-resolution print.

Which aspect ratio should you choose: 1:1, 4:5, or 16:9?

Pick the ideal ratio for your target platform to prevent auto-cropping, compression, or distortion.

1:1Square

1:1 Square Frame

Balanced geometric symmetry that keeps visual attention tightly centered on the subject.

Best for: Instagram feed tiles, profile avatars on social networks, and standard square ecommerce product listings.

4:5Vertical Feed

4:5 Portrait Ratio

The optimal mobile feed format, offering 25% more screen real estate than square without being cropped.

Best for: Instagram portrait posts, Xiaohongshu cover cards, Pinterest pins, and mobile in-feed ads.

16:9Widescreen

16:9 Landscape Widescreen

The universal standard for widescreen displays, presentations, and landscape video platforms.

Best for: Desktop 4K wallpapers, YouTube thumbnails, keynote slides, and responsive website hero banners.

9:16Full Vertical

9:16 Fullscreen Vertical

Designed for immersive, full-height smartphone consumption without letterboxing.

Best for: TikTok & Instagram Reels video covers, Snapchat stories, and phone lock screen wallpapers.

CustomFreeform

Custom Canvas Frame

Unlimited ratio flexibility by dragging handles or entering precise pixel dimensions.

Best for: Print trade-show banners, roll-up displays, magazine spreads, and custom ad units.

How to get the most natural uncropping results

Good source files and intentional canvas framing make outpainted borders look authentic.

01

Start with the highest resolution original

Avoid screenshotting or repeatedly forwarded images. Sharp edge pixels give the model better cues for textures.

02

Expand wide scenes in gradual steps

When expanding a thin vertical strip into an ultra-wide panoramic header, moderate expansions produce the most consistent logic.

03

Use edge prompts only when necessary

Natural landscapes and skies work best with no prompt. Add brief hints only for unique flooring, architectural styles, or decor.

04

Check horizons, lighting angles, and perspective

Review cast shadows and vanishing points. If clipped limbs or cut-off furniture sit on the edge, erase them first.

Build a complete image post-processing workflow

Combine complementary tools for clean compositions, crisp faces, and ultra-high resolution outputs.

01

Before uncropping: remove edge clutter

If an edge cuts through a stray arm or distracting pole, erase it first with Object Remover so the outpainted scene remains clean.

Remove clutter first
02

Before uncropping: sharpen portraits & faces

If your original is soft or low-resolution, restore facial details with Photo Enhancer before expanding the canvas.

Enhance portrait first
03

After uncropping: upscale to 4K / 8K

Extending adds canvas borders, not pixel density. Send your completed wide image to Image Upscaler for tack-sharp print resolution.

What this tool does not do (Boundaries)

Clear boundaries help you pick the right tool for each editing task.

  • It does not stretch or warp original pixels

    If you want higher resolution within the exact same frame, use Image Upscaler. Extender only grows the canvas outwards.

  • It does not generate pictures from blank canvases

    A real photo is required. The new edges are a logical continuation of reality, not a random text-to-image creation.

  • It does not move or recompose your subject

    The person, product, or building remains locked on its original coordinates; only the peripheral canvas is painted.

  • It cannot recover unseen people or logos

    If an object was outside the original camera frame, the model cannot magically reconstruct proprietary logos or real people.

What do creators use AI Image Extender for?

Built for anyone who has a great photo and needs a wider or different crop without sacrificing the original composition.

  • Content creators & social media managers

    Convert vertical camera stills into 16:9 video covers or 1:1 post tiles without chopping off heads or hands.

  • Graphic designers & web developers

    Fit client photos into expansive hero banners, pitch deck slides, and advertising displays that need extra breathing room.

  • Ecommerce brands & independent merchants

    Add clean studio margin around product photos to comfortably accommodate badges, headlines, and pricing.

  • Photographers & wallpaper enthusiasts

    Turn vertical travel captures into expansive desktop wallpapers without awkward black letterboxing or stretched pixels.
