Aspect-ratio crop with a focal point, without distortion
Upload an image or a frame from a landscape video, mark the point that can't be left out of the crop and choose the output format. The tool calculates the exact box in pixels and percentage.
Pick the frame you want to use as a reference to calculate the crop.
Drag the dot to mark which part of the image must always stay visible.
Works with images up to ~40 megapixels and videos up to ~150 MB, depending on your device's memory. For video, the crop doesn't re-encode the file: we give you the coordinates to apply in your editor.
How it works
Upload your image or frame
If it's a video, you pick the exact moment you want to use as a reference.
Mark the focal point
Drag the dot over what can't be left out: a face, a logo, a product.
Pick the format and download
9:16, 1:1, 4:5 or whatever you need. Download the image or copy the coordinates for your video editor.
Crop without losing what matters in the shot
Most of the material produced for vertical video isn't born vertical: a product photo, a frame from an interview shot in 16:9, a horizontal screenshot. Converting that material to 9:16, 4:5 or 1:1 by always cropping from the center assumes something that's almost never true: that the important part of the image is in the middle. In practice, the main subject —a face, a logo, the product— is usually pushed to one side by composition (the rule of thirds photographers and camera operators use places the subject off-center on purpose), and a centered crop ends up cutting exactly what you wanted to show.
The cost of this mistake isn't only aesthetic. When an automatic crop slices half a face out of a thumbnail, or leaves the product out of frame in a photo meant to sell, the content loses its purpose before anyone even reads the caption. And since each platform (or each format within one platform: feed, story, carousel cover) asks for a different ratio, without a way to pin which part of the image to keep, the usual alternative is cropping each version by hand — a slow process that also introduces inconsistency between posts from the same brand.
Pinning a focal point solves the problem at the root: instead of cropping "from the center" or "by eye" in a generic editor, you explicitly mark which point of the image can't fall outside the frame, and the crop is calculated mathematically around that point, respecting the output aspect ratio without distorting the image (no stretching or squashing). For video, rather than promising an automatic crop that reprocesses the whole file —something that can't be done well 100% on the browser side without heavy server tools— the tool hands you the exact coordinates of that crop to apply in the video editor you already use, avoiding an unnecessary second re-encode of the full file.
The available formats cover the most common vertical-video and feed cases: 9:16 for TikTok, Reels and Shorts; 4:5 and 1:1 for feed posts; 3:4 and 16:9 for other uses.
Real use cases
- A product photo shot horizontally for a web catalog needs to become a 9:16 story: without a focal point, the automatic crop cuts the product in half; marking the focal point on the product keeps it whole and centered in the new frame.
- A frame from an interview shot in 16:9, with the guest on the left of the frame (the typical composition of a fixed two-person camera), is cropped to 9:16 without cutting off their face, because the focal point was set on their face and not on the geometric center of the image.
- The same campaign photo needs to go out in three formats on the same day: feed post (4:5), story (9:16) and carousel thumbnail (1:1). Instead of cropping three times by hand, you set a single focal point and generate all three ratios from it.
- A clip from an event shot horizontally, with the speaker pushed to the right of the frame, needs to become a vertical short: the tool gives the exact crop coordinates to paste into the video editor, without re-exporting the whole file inside the browser.
Frequently asked questions
What is the focal point in a crop?
It's the point in the image you want to keep visible inside the crop at all times, like a face, a logo or a product. The tool calculates the largest possible box that keeps that point centered, without distorting the image.
Can I use it with a whole video?
Yes. You upload the video, pick a frame as a reference and the tool gives you the exact crop coordinates (in pixels and percentage) to apply in your video editor, without re-encoding the whole file inside the browser.
Does the image get distorted or stretched?
No. The crop always keeps the original pixel ratio: a region of the image is cropped, never stretched or squashed.
In which formats can I download the result?
PNG (lossless, with transparency if the original had it) or JPG (lighter, with a white background if needed).
What happens if I move the focal point near the edge?
The crop box adjusts so it doesn't go past the limits of the original image, so the focal point may end up slightly off-center inside the final crop instead of losing part of the image.
Is my file uploaded to a server?
No. All the calculation and cropping happen in your browser with canvas. The file never leaves your device.
Why isn't cropping from the center always enough?
Because the important subject of an image is rarely exactly in the middle: photo and video composition usually place it off to one side by the rule of thirds, or the original framing already comes off-center from how it was shot. A centered crop ignores that composition and can cut out just what you needed to keep.
Do I lose quality when cropping?
You lose the part of the image that falls outside the box (that's inherent to any crop), but the portion that is kept isn't recompressed more than necessary to export it.
Can I use the same image for several aspect ratios without marking the focal point again?
Yes. The focal point is set once on the image, and from there you can calculate boxes for different aspect ratios without having to mark it again each time.
