ImgWrench's image cropper lets you crop any image in your browser, freehand or to a fixed ratio, with a live preview of the result. The download contains exactly the pixels inside the frame, at full resolution.

How to crop an image

  1. Drop an image into the tool above.
  2. Pick a ratio, or keep Free.
  3. Drag the frame to move it, and drag a corner or edge to resize it. Zoom in for fine adjustments.
  4. Choose PNG, JPG or WebP and download.

Ratios for common uses

  • 1:1 for profile pictures, product photos and icons.
  • 4:3 for classic photo prints and slides.
  • 16:9 for video thumbnails, banners and presentations.
  • 9:16 for stories, reels and phone wallpapers.

Precise crops

The size next to Crop is the exact width and height of your download. Type W, H, X and Y to set the frame to the pixel, or select the frame and nudge it with the arrow keys: one pixel per press, ten with Shift. The cropper never resizes, so a 1280×720 frame gives a 1280×720 file.

Cropping for a platform

When a site needs one exact size, such as a banner or an emote, a platform resizer does the crop and the resize in one step. See the image sizes for Twitch, Discord, YouTube and more.

Frequently asked questions

How do I crop an image online?

Drop the image into the tool above and a crop frame appears over it. Drag inside the frame to move it and drag a corner or edge to resize it, while the preview shows exactly what you'll get. Pick PNG, JPG or WebP, then download. Use the zoom slider for fine adjustments on large photos, or Reset to start again.

How do I crop an image to a square?

Choose 1:1 under Ratio. The frame becomes the largest square that fits your image, centred, and stays square as you move or resize it. The size shown next to Crop is the exact width and height you'll download, such as 1080×1080, and you can type a width to set it precisely. Square crops suit profile pictures, thumbnails and product photos.

How do I crop a photo to 16:9 or 9:16?

Pick 16:9 for landscape images, such as video thumbnails and banners, or 9:16 for vertical ones like stories and phone wallpapers. The frame snaps to that shape and keeps it while you move and resize it. For a ready-made YouTube size, the YouTube thumbnail resizer crops and resizes in one go.

Can I crop an image to an exact pixel size?

Yes. Type the width and height into W and H, and the position of the top-left corner into X and Y, all in pixels. The cropper never stretches or shrinks your image, so the download is exactly that size. With a fixed ratio, typing a width sets the matching height for you, so a 16:9 crop stays 16:9.

Does cropping an image reduce its quality?

Cropping itself doesn't: the pixels inside the frame are copied as they are, at full resolution. Saving as PNG keeps them exactly. JPG and WebP compress the result, at quality 90 by default, which looks the same for photos; raise the quality slider to 100 if you plan to edit the image again.

How do I crop an image into a circle?

Switch Shape to Circle. The frame turns into a circle you can move and resize, and everything outside it becomes transparent when you save as PNG or WebP. The circle crop tool opens straight in this mode, with tips for round profile pictures, logos and stickers.

Are my images uploaded anywhere?

No. The image cropper runs entirely in your browser, so your images never leave your device and are never sent to a server. The preview, the crop and the file you download are all made locally. You can check this yourself: open your browser's network tab while you crop, and you'll see that no image data is sent anywhere.
