How it works

  1. Upload your tilted photo

    Drop your photo into EditThisPic. Photos with crooked horizons, tilted buildings, or uneven water lines can all be straightened. The AI recognizes what should be level.

    Expect: Most horizon straightening takes 10-15 seconds. The AI fills in any gaps created by rotation automatically.
  2. Describe the fix

    Type your instruction: 'straighten the horizon line' or 'level this photo so the water line is horizontal.' For buildings: 'straighten the photo so the building is vertical.' No marking needed.

    Tip: Be specific about what should be straight: 'make the ocean horizon level' is clearer than just 'fix this photo' for landscapes.

    Copy one of these to get started:

    Ocean or water horizon straighten the horizon line so the water is perfectly level, fill in any gaps naturally
    General landscape level this photo so the horizon is straight, extend the edges naturally to maintain the composition
    Building or architecture straighten this photo so the building is vertical, correct the perspective tilt
    Interior room photo level this room photo so the floor and ceiling lines are horizontal
    2 more prompts
    Group photo with tilt straighten this group photo so the floor and people are level
    Cityscape or skyline straighten the cityscape so the building lines are vertical and the base horizon is level
  3. Review the leveled photo

    Check that the horizon or reference line is now perfectly level. The AI extends the edges to fill any gaps, maintaining the photo's composition. Verify nothing important was cropped.

  4. Adjust if needed

    If the photo still looks slightly off or was rotated too much, describe the adjustment: 'rotate slightly clockwise' or 'the horizon needs to tilt up on the right side.' Fine adjustments are easy to make.

    Tip: Sometimes what looks level in a photo can feel slightly off due to sloping landscapes. Adjust until it 'feels' right, not just technically level.

Quick answers

Do I need to mark the horizon before straightening?

No. Just describe what you want: 'straighten the horizon line.' The AI recognizes horizons, water lines, and reference points automatically.

How do I straighten a tilted horizon in a photo for free?

Upload your photo to EditThisPic and describe the fix: 'straighten the horizon so it's level.' The AI rotates and extends the image in about 15 seconds. It's completely free, requires no account, and downloads with no watermark.

Is there a free horizon straightening tool that doesn't need login?

Yes. EditThisPic straightens horizons for free without requiring any account or signup. Simply upload your photo, describe what needs leveling, and download the result. Great for landscape and travel photos.

Will straightening cut off parts of my photo?

The AI extends the edges to fill in gaps created by rotation, so you typically don't lose content. It intelligently generates matching sky, water, or ground to fill corners. For very large rotations, some minor cropping may occur.

Can I straighten building perspective too?

Yes. You can straighten tilted buildings and correct perspective: 'straighten this photo so the building is vertical.' This fixes the leaning effect caused by shooting tall buildings from ground level.
