✂️ Crop
Precision cropping with aspect ratio presets and dimension targets. Crop a single image at a time with live preview.
Features:
- Aspect Ratios - Free, 1:1 (Square), 16:9, 9:16 (Vertical), 4:3, 3:2
- Dimension Presets - Instagram (1080×1080, 1080×1350, 1080×1920), Facebook (1200×630), YouTube (1280×720)

How to Use:
- Select an image from your uploaded batch
- Choose an aspect ratio or dimension preset
- Drag the crop area to your desired position
- Optionally rotate the crop area
- Click "Crop Image"
💡 Pro Tip: Use dimension presets for social media to ensure your images meet platform requirements perfectly.
📐 Resize
Batch resize images while maintaining aspect ratio. Set maximum dimensions—images smaller than your target won't be upscaled.
Features:
- Batch Processing - Resize all images at once
- Aspect Ratio Preservation - Images stay proportional
- No Upscaling - Prevents quality loss from enlarging images
- Flexible Constraints - Set max width, max height, or both
How to Use:
- Enter maximum width and/or height in pixels
- Click "Resize Images"
- Images fit within your dimensions while maintaining proportions
- Download resized images
⚠️ Important: Images smaller than your specified dimensions will not be enlarged—only images larger than your limits will be resized down.
🗜️ Compress
Reduce file size while controlling quality. Convert between formats and compare before/after with a visual slider.
Features:
- Quality Control - Adjust from 10% to 100%
- Format Conversion - JPEG, PNG, WebP (lossy & lossless)
- Visual Comparison - Before/after slider to check quality
- File Size Preview - See exact savings before downloading
Format Recommendations:
- JPEG - Best for photos, good compatibility (default: 80% quality)
- PNG - Best for graphics with transparency, lossless compression
- WebP (Lossy) - Better compression than JPEG, modern browsers only
- WebP (Lossless) - Better compression than PNG, modern browsers only
How to Use:
- Select quality level (80% recommended for photos)
- Choose output format
- Click "Compress Images" to process all, or compress individually
- Use the before/after slider to verify quality
- Download compressed images
💡 Pro Tip: For web use, 80% JPEG quality offers the best balance of file size and visual quality. For maximum compression, try WebP format—it can reduce file size by 25-35% compared to JPEG.
ℹ️ Metadata
View and remove EXIF data from your images. Protect your privacy by stripping location, camera, and software information.
What is Metadata?
EXIF metadata is hidden information embedded in image files by cameras and phones, including:
- GPS Location - Where the photo was taken
- Camera Settings - Aperture, shutter speed, ISO, focal length
- Date & Time - When the photo was captured
- Device Info - Camera/phone make and model
- Software - Editing apps used
Features:
- View Metadata - See all EXIF data in a readable table
- Export to CSV - Download metadata for record-keeping
- Batch Removal - Remove metadata from all images at once
- Privacy Protection - Prevent location tracking when sharing photos
How to Use:
- Select an image to view its metadata
- Click "Download as CSV" to export (optional)
- Click "Remove Metadata" to clean the image
- Download the cleaned image
🔒 Privacy Note: Always remove metadata before sharing photos online to protect your location and personal information.
Operation Chaining
Operations automatically preserve changes from previous tabs. This means you can:
- 1. Crop → Resize
Resize works on the cropped image - 2. Crop → Compress
Compress works on the cropped image - 3. Resize → Crop
Crop works on the resized image - 4. Crop → Resize → Compress
All operations chain sequentially
✨ Tip: For best results with multiple operations, use Multi-operation tab or follow this order: Crop first, then Resize, then Compress. This ensures each operation works on the processed output from the previous step.

Troubleshooting
Image won't upload
- Check file size is under 50 MB
- Verify image dimensions are under 10,000×10,000 pixels
- Ensure file format is supported (JPEG, PNG, WebP, AVIF, GIF, BMP, TIFF)
- Try a different browser
Processing is slow
- Large images (>10 MP) take longer to process
- Processing 10 images simultaneously requires more browser resources
- Close other browser tabs to free up memory
- Process images in smaller batches (3-5 at a time)
Download doesn't work
- Check your browser's download settings and permissions
- Some browsers block automatic downloads—check for a notification bar
- Try downloading images individually instead of as ZIP
Quality seems poor after compression
- Increase the quality slider (try 85-95% for photos)
- Use PNG for graphics with text or sharp edges
- Try WebP Lossless for best quality with smaller file size
- Use the before/after slider to find the sweet spot
Frequently Asked Questions
Are my images uploaded to a server?
No. All image processing happens locally in your browser using JavaScript. Your images never leave your device.
Why is there a 10 image limit?
Browser-based processing uses your device's RAM. The 10 image limit ensures smooth performance across all devices and prevents browser crashes.
Can I process images larger than 50 MB?
Not currently. The 50 MB limit prevents browser crashes from extremely large files. If you need to process larger images, try resizing them first in another tool.
Does this work on mobile?
Yes, but desktop is recommended. Mobile browsers have less memory and processing power, which can slow down operations or cause issues with multiple large images.
What happens to the original images?
Your original images remain unchanged on your device. All operations create new processed versions that you can download.
Can I undo an operation?
Each tab works on the latest processed version. To start over, simply refresh the page and re-upload your original images.
Is my metadata really removed?
Yes. When you remove metadata, the image is redrawn on an HTML canvas which strips all EXIF data. You can verify this by viewing the metadata before and after removal.
