Crop an image to any aspect ratio, in your browser

Drag the box, pick a ratio or a platform size, and download. Your image is processed on your device and never uploaded.

Drop an image, or click to choose

JPG, PNG, WebP or GIF. It stays on your device.

Need several changes to one photo? The Photo editor does crop, text, filters and blur together.

How it works

  1. Choose your image

    Drop a file in or browse for one. The image is decoded and kept on your device.

  2. Drag the crop box

    Move the box over your subject and drag its edges or corners. Tap a ratio, a platform size or a circle to reshape it around the same spot. The result size updates as you go.

  3. Download the cropped image

    Your browser renders only the selected region to a canvas and exports it. Your original file is untouched.

What cropping does to the file

Cropping removes the pixels outside the box. It does not rescale the pixels that remain, so the kept area stays at its original resolution and quality. The file usually gets smaller, because there are fewer pixels to store.

There is one case where a crop can look soft: cutting a tiny region out of a low-resolution image and then enlarging it for print or a large screen. That is not the crop losing quality; it is the small area being stretched. Start from the highest resolution you have.

Rectangle and circle crops

A rectangle crop keeps a plain four-sided region in your chosen ratio. A circle crop masks the box to a centred circle and leaves the corners transparent, ideal for avatars and logos.

Transparency only exists in PNG and WebP, so a circle crop always exports as a PNG. JPG has no transparency and would fill the corners with a solid colour, turning your circle back into a square.

Why crop in the browser

Most online croppers upload your image to a server and crop it there. This one does all of the work in your browser with the canvas API, so the photo never leaves your device. That matters for screenshots, documents and ID photos you would rather not hand to a stranger.

It is also faster, with no upload-and-wait round trip, and it keeps working offline once the page has loaded.

Tips

Common questions

How do I crop an image to a square (1:1)?
Tap the 1:1 preset. The box turns square around the spot it was on; drag it over your subject, resize it from a corner, then download.
How do I crop an image into a circle?
Switch the shape to circle. The crop exports as a PNG so the corners stay transparent. JPG cannot hold transparency and would fill the corners with a solid colour, so a circle crop always uses PNG.
Does cropping reduce the image quality?
No. Cropping removes the pixels outside the box and leaves the kept area at its original resolution, with no rescale. Quality only suffers if you later enlarge a very small cropped area for print or a big screen.
Does cropping make the file smaller?
Usually yes, because there are fewer pixels to store. How much smaller depends on how much you cut away and the output format you pick.
Are my images uploaded to a server?
No. Cropping happens in your browser using the canvas in your device. The file never leaves your device and nothing is stored or sent anywhere.
What aspect ratio should I use for Instagram or YouTube?
Pick the platform under Social sizes and tap the image type. Instagram square is 1:1 and portrait is 4:5, stories and reels are 9:16, and YouTube thumbnails are 16:9. The table below lists every size with the platform page it came from.
Can I crop to exact pixel dimensions?
The result bar shows the exact pixel size as you drag, and Alt with the arrow keys changes it one step at a time. Cropping never rescales, so to land on an exact size such as 1080 × 1350, crop to the ratio and then use the Resize tool.
How do I crop a passport or ID photo?
Pick the ratio your form requires, crop, and download. Then use the Resize tool to hit the exact pixels and the Compress tool for any file-size limit the form asks for.
Will I lose the parts I crop out?
The downloaded file contains only the cropped area, but your original file is never changed. Keep the original if you might want the full image again.
Which output format should I choose?
JPG for photographs, PNG for graphics or a circle crop that needs transparency, and WebP for the smallest web file where it is supported.
Is there a watermark or a limit?
No watermark, no sign-up, and no file-count limit. The tool is free and runs entirely in your browser.
Does it work offline?
Yes. Once the page has loaded, cropping needs no connection because all of the work happens on your device.
