How to crop an image?
-
Import the photo
Drag a JPG, PNG or WebP image into the box, or select it from your device.
-
Place the frame
Choose an aspect ratio or keep freeform mode, then move the frame and drag its handles. You can also rotate the image a quarter turn or type the dimensions in pixels.
-
Download the cropped image
The image is exported in the same format as the original and at full resolution: the area you keep retains all its pixels.
Precise cropping for every use
Social media formats
1:1 for a profile picture, 4:5 for an Instagram post, 9:16 for a story or TikTok, 16:9 for a video or a screen.
Classic photo formats
4:3, the default format on most smartphones, and 3:2, the format of DSLR cameras and 4 × 6 prints.
Pixel-perfect dimensions
The width and height of the frame are shown in pixels and can be typed in, to get exactly the size you need.
Quality and privacy
Exported at full resolution, in the same format (JPG, PNG or WebP). The photo is processed in your browser: it's never uploaded.
What size for Instagram, TikTok and profile pictures?
Each platform has its own proportions. For an Instagram post, the 4:5 portrait format takes up the most space in the feed: 1080 × 1350 pixels is the standard size. The 1:1 square (1080 × 1080) works for classic posts and for profile pictures, which WhatsApp, LinkedIn or Instagram then display in a circle: keep the face well centered and leave some room around it. Stories, Reels and TikTok use 9:16, or 1080 × 1920 pixels, full screen on a phone. 16:9 (1920 × 1080 or 1280 × 720) is the format of YouTube videos and their thumbnails, computer screens and presentations.
Cropping vs. resizing: what's the difference?
Cropping means cutting off the edges to keep only part of the image: the framing, and often the proportions, change, but every pixel you keep stays intact. Resizing means shrinking or enlarging the whole image without cutting anything. For a 4000 × 3000 pixel photo (4:3) that you want in 16:9, crop first: the frame is then 4000 × 2250 pixels. If the website requires exactly 1920 × 1080, use “Resize Image” afterwards. Avoid doing it the other way around: forcing a 4:3 photo into a 16:9 format without cropping it stretches the image and distorts faces. To make the final file lighter, finish with “Compress Image”.
Cropping without losing quality
The more you cut, the fewer pixels are left: a close-up taken from a 12-megapixel photo may keep only 2 or 3 megapixels, enough for a screen but sometimes tight for a print. So keep an eye on the dimensions shown: for a good-quality 4 × 6 print, aim for about 1800 × 1200 pixels (300 dpi). Crop the original photo rather than an image received through a messaging app, which has often already shrunk and compressed it. If the photo is sideways, rotate it a quarter turn before placing the frame. The tool exports in the same format as the original photo, JPG, PNG or WebP; convert an iPhone HEIC photo first with “HEIC to JPG”.
Frequently Asked Questions
How do I crop a photo into a square?
Choose the 1:1 format, place the frame on the subject and adjust its size with the handles, then download. A square is ideal for a profile picture or an Instagram post.
What size is an Instagram photo?
In 4:5 portrait, 1080 × 1350 pixels; in square, 1080 × 1080; for a story or Reel (9:16), 1080 × 1920. Choose the proportions here, then shrink to the exact dimensions with “Resize Image” if needed.
Does cropping reduce image quality?
The area you keep retains all its pixels: the image is exported at full resolution, without being downsized. It does contain fewer pixels than the whole photo, though, which matters if you want to print it large.
How do I crop a photo on my phone?
Open this page in your phone's browser, import the photo from your gallery or camera roll, place the frame and download the cropped image. There's nothing to install.
Are my photos uploaded to a server?
No. Cropping happens entirely in your browser: the photo never leaves your device. It's free, with no sign-up.
