What is Image Cropping?

Image cropping is the process of removing unwanted outer areas from a photo or illustration. It is used to improve framing, change aspect ratio, remove distractions, or focus on a specific subject. Unlike resizing, cropping reduces the pixel dimensions by cutting away parts of the image.

How to Crop an Image Online

  1. Upload your image by dragging it into the drop zone or clicking to browse.
  2. Adjust the crop box by dragging its edges or corners, or enter precise pixel coordinates.
  3. Choose an aspect ratio preset (1:1, 4:3, 16:9, etc.) or use freeform cropping.
  4. Optionally rotate or flip the image before exporting.
  5. Select your output format (JPG, PNG, or WebP) and quality setting.
  6. Click Download to save the cropped image to your device.

Free Crop vs. Fixed Aspect Ratio

Free crop lets you drag the crop box to any size and position. Fixed aspect ratio constrains the crop box to a specific proportion (e.g., 1:1 for square, 16:9 for widescreen). Use fixed ratios when you need consistent dimensions for social media, printing, or design requirements.

How to Crop to 1:1 Square

Select the 1:1 aspect ratio preset. The crop box will maintain equal width and height as you adjust it. This is ideal for profile pictures, Instagram posts, and product thumbnails.

How to Crop 16:9 and 9:16 Images

Use the 16:9 preset for landscape widescreen images (YouTube thumbnails, presentations) or 9:16 for portrait orientation (Instagram Stories, TikTok, mobile wallpapers). The crop box automatically maintains the selected ratio.

How to Make a Circular Avatar

Enable Circular Crop mode. The tool uses a 1:1 crop box with a circular mask preview. Export as PNG to preserve the transparent circular background. For JPG output, choose a background color (white is recommended).

Crop vs. Resize: What's the Difference?

Cropping removes parts of the image to change its composition and reduce pixel dimensions. Resizing scales the entire image to new dimensions without removing any content. Use cropping to change what's visible, and resizing to change the file dimensions while keeping everything visible.

Does Cropping Reduce Image Quality?

Cropping itself does not reduce quality - it simply selects a portion of the original pixels. However, if you export to JPG with compression, some quality loss occurs. Export to PNG for lossless results, or use high quality settings (90%+) for JPG.

JPG, PNG, or WebP: Which to Choose?

JPG is best for photos with complex colors and gradients. PNG preserves transparency and is lossless, ideal for graphics and circular crops. WebP offers better compression than JPG with optional transparency support, supported by most modern browsers.

Why Are My Phone Photos Rotated Wrong?

Phone cameras embed EXIF orientation data that tells viewers how to display the image. This tool automatically detects and corrects EXIF orientation so your crop coordinates match what you see on screen. The exported image uses the corrected orientation.

Image Metadata and GPS Privacy

By default, exported images have most metadata removed, including EXIF camera info, GPS location, and thumbnails. This helps protect your privacy when sharing images online. Some browsers may not preserve all color profiles during export.

Batch Cropping

Upload multiple images and crop them all at once. Use Separate mode to set individual crop areas for each image, or Unified mode to apply the same aspect ratio and alignment rule to all images regardless of their different dimensions.

Browser-Based Processing

All image processing happens entirely in your browser. Images are never uploaded to any server. This means faster processing, complete privacy, and no file size limits imposed by server infrastructure.

Limitations

  • Animated GIF files will only process the first frame; animation is lost.
  • SVG files are not supported for security reasons.
  • Very large images (over 20,000 px) may fail on devices with limited memory.
  • HEIC files require browser support or a compatible decoder.
  • Maximum 50 images per batch, 30 MB per file, 200 MB total.

Frequently Asked Questions

Are my images uploaded to a server?

No. All image processing happens entirely in your browser. Images never leave your device.

What image formats are supported?

JPG, PNG, WebP, BMP, and static GIF. HEIC is supported if your browser can decode it. SVG is not supported for security reasons.

How do I crop to a fixed aspect ratio?

Select a ratio preset (1:1, 4:3, 16:9, etc.) from the aspect ratio panel. The crop box will maintain that proportion as you adjust it.

How do I make a circular avatar?

Enable Circular Crop mode, adjust the crop area, and export as PNG to preserve the transparent circular background.

Why does circular crop need PNG?

PNG supports transparency, which is needed for the circular shape. JPG does not support transparency and requires a solid background color.

Does cropping reduce image quality?

No. Cropping selects a portion of the original pixels without altering them. Quality only decreases if you export to JPG with compression.

What's the difference between crop and resize?

Crop removes parts of the image. Resize scales the entire image to new dimensions. Use crop to change composition, resize to change dimensions.

Can I crop multiple images at once?

Yes. Upload multiple images and use batch processing. Choose Separate mode for individual settings or Unified mode for consistent rules.

Can I apply the same crop to different-sized images?

Yes. Unified batch mode uses relative percentages and alignment rules, not fixed pixel coordinates, so it works correctly across different image sizes.

Why are my phone photos rotated incorrectly?

Phone cameras embed EXIF orientation data. This tool automatically detects and corrects it so the preview and export match what you see.

Does animated GIF keep its animation after cropping?

No. Only the first frame is processed. Animation is lost in the output.

Can I crop HEIC images?

Yes, if your browser supports HEIC decoding. The decoder is loaded on demand when a HEIC file is detected.

Are EXIF and GPS data preserved in the output?

By default, metadata is removed from exported images to protect privacy. This includes GPS location, camera info, and thumbnails.

Why does the exported color look slightly different?

Some browsers may not preserve the original ICC color profile during canvas export. The difference is usually subtle.

Why can't very large images be processed?

Browsers have canvas size limits. Images over 20,000 px may exceed these limits. Try reducing the output size or using a desktop browser.
