How to use this tool

  1. Upload a JPG, PNG, or WebP image.
  2. Pick Custom to drag the crop box freely. Width and height stay in sync with the box. Edit those fields to reshape the crop. Or choose Square, Portrait 4:5, Wide 16:9, or Passport 35×45.
  3. Download as JPG, PNG, or WebP. Choose PNG if you need a transparent background.

Frequently asked questions

What does the image cropper do?▾

It trims an image down to a chosen frame, cutting away everything outside the selection instead of scaling the whole picture. This is different from resizing, which keeps the full scene but changes its scale, or compressing, which shrinks file size without changing what's visible. Cropping is what you need when a photo has extra background you don't want, or when a platform expects a specific aspect ratio like a square profile photo.

Who is this for?▾

Anyone preparing a tighter photo for an Instagram or LinkedIn post, a profile picture, a slide in a presentation, or a form that asks for a passport-style photo at a specific ratio reaches for a cropper. It also suits anyone who wants to remove a distracting background element, cut a photo down to one person from a group shot, or fit a wide landscape photo into a square thumbnail without opening a full photo editor.

Which crop presets are available?▾

Custom lets you drag the crop outline freely or lock any width to height ratio, with width and height fields staying in sync with the box. Square 1:1, Portrait 4:5, Wide 16:9, and Passport 35x45 are also available as fixed presets.

What file type do I get?▾

Choose JPG, PNG, or WebP before you download. PNG keeps transparency, JPG is usually smaller for photos, and you can upload any of the three formats to start.

Is this official for passport photos?▾

Use it as a starting point only. Governments set exact size, background, and face position rules that change over time, so always check current official guidance before submitting documents.

Is cropping private?▾

Yes. Your image is processed locally in your browser and is never uploaded to our servers.

Can I crop on mobile?▾

Yes, on most modern phones you can touch and drag the crop area directly. Very large photos may feel slightly slower on mobile than on desktop.

Does cropping reduce file size?▾

Cropping removes pixels outside the frame, which usually makes the file smaller since there's less image data to encode. The output format and quality you choose also affect the final size.
