Why do your photos end up looking crooked?
It happens all the time: you're trying to capture a receipt, a page from a book, or notes from a meeting, but you can't get perfectly parallel to the surface. This results in a "trapezoid" effect where one side is wider than the other, making text look stretched and hard to read.
PerspectiveFix solves this by using a professional-grade perspective warp algorithm. By simply marking the four corners of your document, the tool mathematically "pulls" the image flat, giving you a clean, rectangular result as if it were scanned by a high-end office scanner.
Designed for your everyday needs:
- ✅ Professional Document Scans: Turn crooked photos of receipts or contracts into perfectly flat, readable documents.
- ✅ Save Your Study Notes: Straighten whiteboard lectures and book pages so you can focus on learning, not squinting.
- ✅ Architecture & Real Estate: Easily fix tilted horizontal or vertical lines in photos of buildings and room interiors.
- ✅ Clean Product Photography: Make your packaging and box photos look flat and professional for your online store.

Frequently Asked Questions
Is this tool really free?
Yes, PerspectiveFix is a 100% free online perspective correction tool. There are no hidden fees, no subscriptions, and we don't add watermarks to your work.
Do I need to upload my private photos to a server?
No. Unlike other "online" tools, our processing happens locally on your device. Your photos are never sent to a server, making it the safest way to fix sensitive documents like contracts, IDs, or personal notes.
Can I use this on my phone?
Absolutely. It's designed to be lightweight and works directly in any modern mobile browser. The touch-friendly corner handles make it easy to fix your "scanned" photos on the go.
What image formats can I use?
You can use JPG, PNG, WebP, and most common image formats. You can also paste an image directly from your clipboard by pressing Ctrl+V (or Cmd+V on Mac).
How does the perspective correction actually work?
When you drag the four corners, the tool calculates a 3D perspective transformation. It then "pulls" those corners to form a perfect rectangle, straightening your image mathematically. Think of it like stretching a rubber photo until it looks perfectly flat and centered.
Why is PerspectiveFix better than just cropping?
Cropping only cuts out a piece of the image, but it doesn't fix the tilt or "keystone" effect. PerspectiveFix actually warps the pixels to correct the angle, ensuring that text is aligned and proportions are preserved.
Is there a limit to how many photos I can fix?
No, there are no limits. You can use PerspectiveFix as many times as you need. Since the processing happens on your own computer, we don't have to worry about server costs, and we're happy to keep it free for everyone.
