About This Tool
Introduction: Crop Images Online Free with Trencada
Need to remove unwanted edges, tighten a composition, or isolate the subject of a photo? The Crop Image tool from Trencada makes it easy to crop images online without installing photo-editing software. Upload a JPG, PNG, or WebP image, drag a selection box over the part you want to keep, and download the cropped result as PNG or JPG — rendered at your image's full original resolution.
How to Use the Crop Image Tool
Cropping an image on Trencada takes just a few steps:
- Upload your image: Drag and drop an image onto the drop zone, or click it to choose a file from your device (JPG, PNG, and WebP supported).
- Position the crop box: Drag the selection box to move it over the part of the image you want to keep.
- Resize the selection: Drag the handles on the box to adjust it — corner handles when an aspect ratio is locked, any of the eight handles in Free mode. A live readout shows the exact selection size in pixels.
- Lock an aspect ratio (optional): Choose Free, 1:1, 4:3, 3:4, 16:9, or 9:16 to keep the selection at fixed proportions.
- Choose the output format: Pick PNG or JPG from the "Save as" dropdown.
- Crop and download: Click "Crop & Download" to save the cropped image. The file downloads using your original filename with -cropped appended — for example, photo-cropped.png.

Can I crop a photo online?
Yes. Upload your photo, drag the selection box over the area you want to keep, and click "Crop & Download".
Can I remove unwanted parts of an image?

What image formats can I crop?
You can upload JPG, PNG, and WebP images, and download the cropped result as PNG or JPG.
Do I need to install image-editing software?
No. The Crop Image tool works entirely in your web browser on desktop and mobile.
Will cropping reduce image quality?
The selection is cropped at your image's full original resolution, so the kept area retains its quality. PNG output is lossless; JPG output uses high-quality compression (92%).
Are my images uploaded to a server?
No. The tool runs entirely in your browser — your image is never uploaded anywhere and stays on your device.
What will the downloaded file be named?
Your original filename with -cropped added before the extension — for example, photo.png becomes photo-cropped.png.
Can I crop images on my phone?
Yes. The crop box supports touch, so you can drag and resize the selection on phones and tablets.
Can I crop more than one image at a time?
No. The cropper works on one image at a time. Finish and download the first crop, then choose another image for the next one.
Can I start over with a different image?
Yes. Use the reset option or choose another image to clear the current crop and load a new photo.
Can I rotate or flip an image before cropping?
No. This tool crops only. If you need rotation or flipping, prepare the image in an editor first, then crop the result here.
Does it show the selected size in pixels?
Yes. Below the preview you see the selection size in pixels, plus the source image size, and it updates live as you drag or resize the box.
