We support all major image formats including JPEG, PNG, GIF, WebP, and BMP. The output format automatically matches your input format to preserve compatibility. For example: upload a PNG, get a PNG output; upload a JPEG, get a JPEG output. We also preserve transparency for PNG and GIF images, and maintain original color profiles and metadata when possible.

You can crop images up to 50MB in size. This limit ensures optimal performance and prevents browser memory issues. For larger files, we recommend: 1) Use our compression tool first to reduce file size, 2) Resize the image to smaller dimensions, or 3) Convert high-resolution formats like TIFF to JPEG before cropping. The tool automatically optimizes memory usage during processing to handle large images efficiently.

No, absolutely not. All image processing happens locally in your browser using JavaScript and HTML5 Canvas API. Here's how it works: 1) Your image is loaded directly into browser memory, 2) Processing occurs entirely on your device's CPU/GPU, 3) Results are generated locally, 4) Nothing is transmitted to our servers. This ensures complete privacy and works even offline. Your images never leave your device and no server uploads occur.

This tool processes one image at a time for maximum precision and control. However, you have several options for multiple images: 1) Use our batch processing tool for applying identical crop settings to multiple images, 2) Save your crop settings (aspect ratio and position) and quickly apply them to subsequent images, 3) Use browser tabs to process multiple images simultaneously. Each approach ensures consistent results while maintaining processing speed.

We provide extensive aspect ratio options: 1) **Preset ratios**: 1:1 (Instagram square), 4:3 (standard photo), 16:9 (widescreen), 3:2 (classic 35mm), 5:4 (medium format), and 2:3 (portrait), 2) **Social media optimized**: Facebook cover, Instagram story, YouTube thumbnail, Twitter header, 3) **Custom ratios**: Enter any ratio like 7:5 or 3:4, 4) **Free crop**: Drag corners freely without constraints, 5) **Lock ratio**: Maintain proportions while resizing. All ratios include visual guides and real-time preview.

No, cropping is a lossless operation that maintains 100% of the original image quality. Here's what happens: 1) **No compression**: We don't re-encode or compress the image data, 2) **Pixel-perfect**: Original pixels remain unchanged in terms of color and sharpness, 3) **Resolution preserved**: The cropped area retains its original DPI/resolution, 4) **Metadata maintained**: EXIF data, color profiles, and other metadata are preserved when possible. The only change is removing unwanted areas while keeping the desired portion at full quality.

Our cropping tool offers pixel-perfect precision with several accuracy features: 1) **Zoom functionality**: Zoom up to 400% for precise corner placement, 2) **Grid overlay**: Optional rule-of-thirds and grid guides for better composition, 3) **Coordinate display**: Real-time X,Y coordinates and dimensions, 4) **Keyboard controls**: Use arrow keys for 1-pixel adjustments, 5) **Snap to edges**: Automatically snap to image borders for clean crops. The tool processes images at full resolution, ensuring no precision loss during cropping operations.

Since all processing happens locally, your original image remains safe on your device. However, any unsaved cropping work will be lost. To minimize this risk: 1) **Auto-save preview**: The tool automatically saves your crop preview as you work, 2) **Session storage**: Crop settings are temporarily stored in your browser, 3) **Quick recovery**: Simply re-upload the same image and your last crop settings will be suggested, 4) **Download regularly**: Save intermediate results for complex cropping sessions. We recommend downloading your results immediately after cropping to ensure you don't lose your work.
