Our tool stands out with mobile-optimized touch cropping, 16+ format support including PDF with exact sizing, browser-based processing for privacy, professional-grade compression algorithms, movable crop selections, real-time size preview, and support for both percentage and dimension-based resizing methods.

After uploading your image, select "Dimensions" mode and enter your desired width and height values. You can choose units (pixels, inches, cm, mm), enable aspect ratio locking to maintain proportions, or manually set exact dimensions for precise control.

Absolutely! Switch to "Percentage" mode and enter any value from 1% to 250%. For example, enter 50% to make your image half the original size, or 200% to double it. The percentage method automatically maintains aspect ratio and shows real-time size updates.

Click and drag on the image preview to select the area you want to keep. A blue selection box will appear. You can resize this selection by dragging the corners or move it by clicking and dragging the entire selection. Click "Apply Crop" to crop the image, or "Cancel" to remove the selection.

Yes! Once you've created a crop selection, you can click and drag it to reposition it anywhere on your image. This is especially useful for fine-tuning the crop area before applying it. The feature works on both desktop and mobile devices.

Aspect ratio locking maintains the original proportions of your image when resizing. When enabled, changing the width automatically adjusts the height (and vice versa) to prevent distortion. This ensures your images look natural and professional after resizing.

Yes! Our tool is perfect for social media optimization. Common sizes include: Instagram posts (1080×1080), Instagram stories (1080×1920), Facebook cover (1200×630), Twitter header (1500×500), LinkedIn banner (1584×396). Simply enter the platform's recommended dimensions for perfect results.

We support 16+ formats including JPG/JPEG, PNG, WEBP, GIF, PDF, TIFF, PSD, RAW, HEIF, AVIF, SVG, BMP, ICO, TGA, and EPS. You can upload in any supported format and convert to any other supported format while resizing.

For web use, WEBP offers the best compression with excellent quality, reducing file sizes by 25-35% compared to JPEG. For compatibility, JPEG works universally. PNG is best for images with transparency or text. AVIF provides even better compression but has limited browser support.

Yes! When you download as PDF, the file will have exactly the same dimensions as shown in the "Current Size" display. The PDF page size matches your image size precisely, making it perfect for printing or document inclusion with exact measurements.

Our tool uses advanced algorithms to maintain image quality while reducing file size. Choose WEBP format for best compression, or reduce dimensions while maintaining quality settings. The real-time preview shows exact file size before download, helping you balance quality and file size.

JPG uses lossy compression, creating smaller files but with some quality loss, ideal for photos. PNG uses lossless compression, maintaining perfect quality with larger file sizes, perfect for graphics, logos, and images requiring transparency. Choose based on your specific needs.

Yes! Simply upload your image, leave the dimensions unchanged, select your desired output format, and download. This allows you to convert between any supported formats (JPG to PNG, PNG to WEBP, etc.) while maintaining original dimensions.

Absolutely! Our tool is fully mobile-optimized with touch-friendly cropping, responsive design, and intuitive finger gestures. All features work seamlessly on smartphones and tablets, including precise crop selection, dimension inputs, and format selection.

Simply touch and drag on the image preview to select the area you want to keep. A crop selection will appear with a slightly thicker border for easier touch interaction. You can move this selection by touching and dragging it to different positions. Then tap "Apply Crop" to crop the image.

Yes! Once you've selected a crop area, you can touch and drag it to move it to different positions on your image before applying the crop. The mobile interface includes larger touch targets and improved gesture recognition for precise control.

The mobile experience is optimized for touch interaction with larger buttons, stacked layouts for better readability, and touch-friendly crop selections. All functionality remains the same, but the interface adapts for comfortable mobile use with finger-friendly controls.

Yes! On mobile devices, you can choose to upload existing photos from your gallery or take a new photo directly with your camera. The upload button will present both options when accessed from a mobile device with camera capabilities.

You can resize using pixels (px), inches (in), centimeters (cm), or millimeters (mm). This flexibility allows for precise control whether you're designing for web (pixels), print (inches/cm), or professional printing requirements (mm).

The size slider provides quick resizing from 1% to 250% of the original size. As you move the slider, you see real-time updates of dimensions and file size. It's perfect for quick adjustments and finding the optimal size balance between quality and file size.

Currently, our tool processes one image at a time for optimal quality and control. However, you can quickly process multiple images by using the "Upload New Image" button after each download, maintaining your preferred settings for consistent results across multiple images.

Lossless compression reduces file size without losing any image quality or detail. Our tool uses advanced algorithms to optimize file size while preserving every pixel of your original image. This is particularly effective with PNG and WEBP formats.

Our previews are extremely accurate. The dimensions shown match exactly what you'll download, and file sizes are calculated in real-time using the actual compression algorithms. This helps you make informed decisions before downloading.

Check that your file is under 10MB and in a supported format (JPG, PNG, WEBP, GIF, etc.). Ensure you have a stable internet connection. If problems persist, try refreshing the page or using a different browser. Very large or corrupted files may fail to upload.

Quality loss typically occurs when significantly enlarging images beyond their original size. For best results, avoid scaling above 150% of original size. Choose PNG for graphics or WEBP for photos. If uploading JPG, start with high-quality originals.

Ensure you're clicking and dragging on the image itself (not surrounding areas). Make the selection larger than the minimum size (20px on desktop, 30px on mobile). If using mobile, try using a single finger for selection. Refresh the page if the crop area becomes unresponsive.

Large images (over 5MB) may process slowly on older devices. Try closing other browser tabs, reducing image size before upload, or using a more recent device/browser. The tool works best on devices with at least 2GB RAM and modern browsers.

File sizes should match very closely (within 1-2%). Small differences may occur due to browser variations or metadata inclusion. PDF files match exactly as they use precise sizing. If discrepancies are large, try refreshing and re-processing the image.

No! All image processing happens directly in your browser using client-side JavaScript. Your images never leave your device or get uploaded to our servers. This ensures complete privacy and security of your personal photos and documents.

Absolutely! Since all processing occurs locally in your browser, your sensitive images remain completely private. No data transmission to external servers means no risk of interception, storage, or unauthorized access to your private photos.

We collect only basic analytics data (page views, general location) to improve our service. We never collect, store, or track your images, personal information, or detailed usage patterns. No registration means no personal data collection.

The tool requires an initial internet connection to load the page and scripts. Once loaded, image processing works offline since it's browser-based. However, downloading results and accessing the page initially requires internet connectivity.

The current maximum file size is 10MB per image. This limit ensures optimal performance across all devices while accommodating most user needs. For larger files, consider reducing quality/size before upload or using professional desktop software.

Our tool works on all modern browsers including Chrome, Firefox, Safari, Edge, and mobile browsers. We require HTML5 Canvas support and JavaScript enabled. Internet Explorer is not supported due to limited modern web standards support.

You can resize up to 250% of original dimensions or approximately 16,000 pixels in either direction, limited by your device's memory and browser capabilities. Very large outputs may be slower to process on older devices.
