How It Works

🔒

100% Private

Your images never leave your device. All cropping and processing uses the HTML5 Canvas API in your browser. No uploads, no server storage, complete privacy.

📐

Preset Aspect Ratios

Choose from Free, 1:1 (square), 4:3 (standard), 16:9 (widescreen), or 3:2 (classic). The crop region automatically maintains the selected ratio.

🔍

Zoom Control

Use the zoom slider to scale the image from 10% to 200%. This helps you make precise crop selections on both small details and large images.

💾

PNG & JPEG Export

Download your cropped image as lossless PNG or as JPEG with adjustable quality (10-100%). Control the output quality to balance file size and image fidelity.

About Image Cropping

Image cropping is the process of removing unwanted outer areas from an image to improve framing, change the aspect ratio, or focus on a specific subject. Cropping is one of the most fundamental image editing operations and is used in photography, web design, social media, and document preparation.

Common Aspect Ratios

Image Format Comparison

PNG is a lossless format ideal for graphics, screenshots, and images with transparency. Files are larger but preserve every pixel perfectly. JPEG is a lossy format best for photographs. It achieves much smaller file sizes through compression, but introduces artifacts at lower quality settings. Choose PNG when quality matters most and JPEG when file size is a priority.

Frequently Asked Questions

What image formats can I upload?
You can upload PNG, JPEG, GIF, BMP, WebP, and SVG images. The tool uses the browser's built-in image decoding, so any format your browser supports will work.
Is my image uploaded to a server?
No, absolutely not. All image processing happens entirely in your browser using the HTML5 Canvas API. Your images never leave your device. The tool works offline after the page loads.
What aspect ratios are available?
Five presets: Free (no constraint), 1:1 (square, great for profile pictures), 4:3 (standard photo), 16:9 (widescreen, great for YouTube and presentations), and 3:2 (classic 35mm photo ratio).
Can I adjust JPEG quality?
Yes, when JPEG is selected as the output format, a quality slider appears. You can set quality from 10% to 100%. Lower values mean smaller files but more compression artifacts. 80-90% is a good balance for most use cases.
Is there a maximum image size?
There is no enforced size limit. However, very large images (20+ megapixels) may process slowly depending on your device. Most images from phones and cameras work perfectly fine.
Is this tool free?
Yes, completely free with no sign-up, no watermarks, and no usage limits. Crop as many images as you need, as many times as you want.
