How it works

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.
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
Try This →

General landscape level this photo so the horizon is straight, extend the edges naturally to maintain the composition
Try This →

Building or architecture straighten this photo so the building is vertical, correct the perspective tilt
Try This →

Interior room photo level this room photo so the floor and ceiling lines are horizontal
Try This →

Group photo with tilt straighten this group photo so the floor and people are level
Try This →

Cityscape or skyline straighten the cityscape so the building lines are vertical and the base horizon is level
Try This →
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.
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.

If something looks off

Photo was rotated but now looks wrong

Why: Sometimes natural slopes in landscapes can look unnatural when technically leveled.

Try: rotate the photo back slightly, make it look naturally balanced rather than perfectly level

Try This →

Tip: Trust your eye - sometimes a 'correct' level looks wrong if the landscape naturally slopes

Important content was cropped

Why: Rotation can cut off corners of the image.

Try: straighten the photo but extend the edges more generously to keep all the important content

Try This →

Tip: The AI fills in edges, but you can specifically ask it to preserve certain areas

Fill-in areas look unnatural

Why: The AI's edge extension might not perfectly match complex patterns or textures.

Try: re-straighten and blend the extended edges more naturally with the sky/water/ground

Try This →

Tip: Simple areas like sky and water fill in best; complex patterns may need touch-up

AI changed something besides the rotation

Why: The AI may have interpreted the request as needing other corrections too.

Try: only rotate the photo to straighten the horizon, don't change anything else about the image

Try This →

Tip: Be specific that you only want rotation, not other edits

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. Only use markers if the AI straightens the wrong reference line.

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.
