Crop Image

Crop a photo to exactly the area you want — freeform or locked to a ratio like 1:1 or 16:9 — right in your browser. Free, instant, and private: the image is never uploaded.

How to crop an image with Allypdf

  1. Load the image you want to crop.
  2. Drag the crop box, optionally locking an aspect ratio.
  3. Apply the crop locally.
  4. Download the cropped image.

Why "no upload" matters here

Cropping is often about removing what should not be seen — other people in the frame, an address in the background, the rest of a screenshot. It would be self-defeating to upload the whole uncropped image to a server just to cut a piece out of it. Allypdf crops on your device, so the parts you removed were never shared with anyone.

Common uses

  • Crop a group photo down to a square headshot for a profile picture.
  • Cut a single chart out of a full-screen screenshot.
  • Trim distracting background from a product photo.
  • Crop an image to 16:9 so it fits a slide without stretching.

Frequently asked questions

How do I crop an image online for free?

Open the Crop Image tool, drag the crop box over the area to keep, and download the result. Free, no watermark, no account needed.

Can I crop to a square or a specific ratio?

Yes. Lock the crop box to presets like 1:1 or 16:9 for profile pictures and thumbnails, or crop freely to any shape.

Does cropping reduce image quality?

No. The kept area is exported at its original pixel quality — cropping removes pixels outside the box but never resamples the ones inside it.

Is my photo uploaded while cropping?

No. The image loads into your browser only, so personal photos stay on your device.

What size should a profile picture be?

Start with a 1:1 square crop — nearly every platform displays profile photos square or circular. Keep the subject centered with some headroom, since circular masks clip the corners, then resize the square to the site's recommended dimensions with our Resize Image tool if needed.
