How to straighten a photo: open it in your editor's Crop tool and drag the Straighten dial (usually ±45°) until a straight edge lines up with the grid. On iPhone, tap Edit, then Crop. If edges lean inward like a box shot from above, use Perspective (Vertical/Horizontal) or Lightroom's Upright instead. Expect to crop roughly 2–10% off the edges.
A tilted photo is one of the easiest problems to fix and one of the most noticeable when left alone. A crooked horizon, a box that leans to the left or a framed print that looks like a trapezoid makes a listing look careless. The fix depends on which problem you have: a simple tilt needs rotating, while converging lines need perspective correction. This guide covers both, step by step, in the apps you already have.
- Tilted horizon or edge: rotate with the Straighten dial in the Crop tool.
- Edges leaning in (keystone): use Perspective, Vertical/Horizontal or Upright, not rotation.
- Every fix crops the edges, so leave extra space around the product when you shoot.
- Best fix is at the shoot: camera level, centered on the product, lens parallel to its front.
- For artwork and boxes: Lightroom's Upright or Photoshop's Perspective Crop squares them up exactly.
Rotate or perspective: which fix do I need?
Use rotation when the whole photo is tilted; use perspective correction when parallel lines converge. Picking the wrong one is why many "straightened" photos still look off.
| Problem | What it looks like | Tool to use |
|---|---|---|
| Tilt | Horizon or table edge slopes; everything is rotated the same amount | Straighten / Rotate |
| Vertical keystone | Sides of a box or frame lean inward toward the top or bottom | Vertical perspective |
| Horizontal keystone | One side of the object looks taller than the other | Horizontal perspective |
| Both | Object looks like an irregular trapezoid | Upright Full / Guided, or Perspective Crop |
| Lens bulge | Straight edges curve near the frame's edges | Lens or distortion correction |
Keystone distortion comes from the camera not being square to the subject. Tilt your phone down at a box on a table and the top of the box looks wider than the bottom. Shoot a painting from slightly to one side and one edge looks taller. Rotation can't fix either, because the lines aren't just tilted, they're converging.
How do I straighten a photo on iPhone?
Open the photo, tap Edit, then Crop. Photos often straightens automatically when it detects a horizon; if not, use the dials yourself.
- Tap Edit, then the Crop tab.
- Choose Straighten and drag the dial until edges line up with the grid.
- For leaning edges, choose Vertical or Horizontal perspective and adjust until the sides are parallel.
- Use the rotate button (square with an arrow) for 90° turns.
- Tap Done. The original stays available through Revert.
Labels and icon positions shift a little between iOS versions, so the layout on your phone may differ slightly.
How do I straighten a photo on Android or Google Photos?
In Google Photos, open the photo, tap Edit, then Crop, and use the Straighten dial. For leaning edges, use Perspective and drag the corner points to the corners of the object.
Google removed perspective correction in its 2025 editor redesign and restored it in late 2025, so whether you see it depends on your app version. Samsung Gallery has its own straighten and perspective controls in the crop screen. Snapseed offers Rotate (with automatic leveling) and a dedicated Perspective tool; on iPhone both sit in the Tools tab since the 3.0 redesign.
How do I straighten a photo in Lightroom?
Use the Straighten tool in the Crop panel for tilt, and the Upright buttons in the Geometry panel for perspective.
- Straighten: in Crop, drag the Angle slider, or pick the Straighten tool and draw a line along something that should be level. Auto straightening is there too.
- Upright Level: fixes tilt only.
- Upright Vertical: fixes tilt and leaning verticals. Good for boxes and bottles shot from slightly above.
- Upright Full: fixes tilt, vertical and horizontal keystone together.
- Upright Auto: a balanced correction that avoids extreme distortion.
- Upright Guided: draw two to four lines along edges that should be straight. The most precise option for artwork and packaging.
- Constrain Crop: tick it to crop away the empty corners that perspective correction creates.
Lightroom mobile has the same Upright options under Geometry.
How do I straighten a photo in Photoshop?
For tilt, select the Crop tool, click Straighten in the options bar and draw a line along an edge that should be level. For keystone, use one of these:
- Perspective Crop tool (grouped with the Crop tool): click the four corners of the object and Photoshop squares it up and crops in one step. Ideal for flat artwork and box fronts.
- Edit > Transform > Perspective or Distort: drag corner handles manually. Turn on a grid or guides so you can see when edges are parallel.
- Filter > Camera Raw Filter > Geometry: the same Upright options as Lightroom.
When you rotate in Photoshop with Content-Aware turned on in the Crop tool's options, it fills the empty corners instead of cropping them. Check the filled areas carefully; they work on plain backgrounds but can look odd on detailed ones.
Strong perspective correction stretches the image. A bottle can come out taller and thinner than it really is. Compare proportions with the real product, and if the correction is huge, reshoot with the camera level instead.
How do I straighten product boxes and packaging?
Shoot the box straight on at the height of its center, then use Upright Vertical or Guided for any small lean that's left. Packaging is full of straight lines, so even a 1° tilt is visible.
- Camera height: lens level with the middle of the front panel.
- Camera angle: back of the phone parallel to the box front. Use the camera's grid and level indicator.
- Distance: step back and zoom in slightly (2× on most phones). A longer lens makes less perspective distortion than shooting close with a wide lens.
- Correct: Upright Vertical or Guided for the lean; Straighten for any leftover tilt.
- Check: the vertical edges should be parallel to the frame's sides.
For three-quarter angle shots, where you want to see the front and a side, keep vertical edges vertical but leave the natural horizontal perspective. Fully squaring a three-quarter shot makes the box look strangely flat.
How do I straighten a photo of artwork?
Use the Perspective Crop tool in Photoshop or Upright Guided in Lightroom, clicking or drawing along the artwork's four edges. Artwork needs exact right angles because buyers compare the image to the print and the frame.
Prevent most of it at the shoot: hang or lay the artwork flat, put the camera on a tripod centered on the piece, and keep the lens parallel to its surface. Our guide on how to photograph artwork for prints covers lighting, glare and color for art in detail.
Why does straightening crop my photo?
Rotating a rectangle leaves empty triangles in the corners, and the editor crops them away. A 3° rotation crops away noticeably more than you'd expect, and perspective correction can crop even more. The table shows rough ranges.
| Correction | Typical edge loss | Shoot with |
|---|---|---|
| 1–2° tilt | Small, a few percent | A little space around the product |
| 3–5° tilt | Noticeable, often 5–10% | Generous space |
| Mild keystone | Moderate | Space on all sides |
| Strong keystone | Large, uneven | Reshoot instead |
If there's still room around the product, our free image cropper trims the straightened photo to an exact shape such as 1:1 or 4:5 in your browser. If the crop leaves the product too tight for the format you need, the AI image extender (8 credits per size) adds space around it at channel sizes such as 2048×2048 for Shopify or 1080×1350 for Instagram, filling the new area instead of cropping the product. For a plain square with padding, the free square image maker pads the photo with white or any color in your browser. More on this in resizing an image for Instagram without cropping.

AiArter doesn't rotate or correct perspective for you, so straighten first in any editor above. After that, it handles the parts that usually come next.
- White main image (4 credits): the product is cut out and placed centered at about 85% of a 2000×2000 frame on pure white, so an uneven crop from straightening no longer matters. A cutout won't fix a tilted product, though; straighten the product itself first.
- Channel sizes (8 credits each): Etsy 2000×1600, Pinterest 1000×1500, Story 1080×1920 and more, with extra space filled by AI.
- Bulk: up to 50 photos per batch, one ZIP download, failed photos not charged.

Frequently asked questions
How do I straighten a crooked photo?
Open the photo in your editor's Crop tool and drag the Straighten dial until a straight edge lines up with the grid. On iPhone tap Edit, then Crop; in Google Photos tap Edit, then Crop; in Lightroom and Photoshop use the Straighten tool in Crop.
How do I fix a photo that looks tilted backwards?
That's vertical keystone distortion, caused by tilting the camera up or down. Use Vertical perspective on iPhone, Perspective in Google Photos, Upright Vertical in Lightroom, or the Perspective Crop tool in Photoshop.
Can you straighten a photo without cropping it?
Not completely, because rotating leaves empty corners. You can fill them with Photoshop's Content-Aware crop option or extend the image with an AI extender, but check the filled areas closely.
What is Upright in Lightroom?
Upright is Lightroom's automatic perspective correction in the Geometry panel. Its modes are Auto, Level, Vertical, Full and Guided; Guided lets you draw lines along edges that should be straight.
How do I straighten a picture of a painting?
Use Photoshop's Perspective Crop tool or Lightroom's Upright Guided and mark the painting's four edges. To avoid big corrections, shoot from a tripod centered on the painting with the lens parallel to it.
Why does my straightened photo look stretched?
Strong perspective correction stretches parts of the image to make lines parallel. Use a gentler setting, adjust the aspect slider if your editor has one, or reshoot with the camera level and square to the subject.
