Can I crop an image to a circle online?

Set equal width and height values in Trndinn's Image Cropper to get a square crop, then apply it. For circular output, use the circle crop option in the advanced settings.

Does cropping an image reduce file size?

Yes. Cropping removes pixels, which reduces the file size proportionally to how much of the image you remove.

What is the best way to crop a photo for Instagram?

For Instagram square posts, crop to 1:1 (1080×1080 px). For portrait, use 4:5 (1080×1350 px). For Stories, use 9:16. Trndinn's cropper lets you enter exact pixel dimensions.

Is there a file size limit for the image cropper?

No. Trndinn's image cropper is entirely browser-based — your file is never uploaded, so there is no server-side size limit.

What is image cropping?

Image cropping is the process of removing unwanted outer areas from a photo to improve composition, change the aspect ratio, or focus on a specific subject. Unlike resizing, cropping removes pixels rather than scaling them — the remaining area retains its original resolution and quality.

Trndinn's Image Cropper runs 100% in your browser using the HTML5 Canvas API. Your photos never leave your device. Supports pixel-perfect coordinates, preset aspect ratios (1:1, 16:9, 4:3, 3:2, 9:16), and outputs in JPG, PNG, WebP, GIF, BMP, and TIFF. Over 3.2 billion images are shared on social media daily [Photutorial, 2025], and proper cropping is the single fastest way to improve visual impact.

Frequently asked questions

Upload your image to Trndinn's Image Cropper, enter the exact Width and Height in pixels (plus optional X/Y offset), and click "Crop & Download." The output file is exactly the dimensions you specified.

What aspect ratio should I use for Instagram?

Instagram supports 1:1 (square posts, 1080×1080), 4:5 (portrait, 1080×1350), and 16:9 (landscape, 1080×608). Stories and Reels use 9:16 (1080×1920). Use the preset buttons in our cropper to snap to these ratios instantly.

Does cropping reduce image quality?

No — cropping preserves the original pixel data of the selected area. Only the removed outer portions are discarded. The cropped region remains at full resolution.
