Frequently Asked Questions
What aspect ratios can I crop to?
You can crop to any aspect ratio freely, or lock to presets: 1:1 (square/Instagram), 16:9 (widescreen/YouTube), 4:3 (standard), 3:2 (DSLR/print), 2:3 (portrait), 9:16 (vertical/Stories). Enter custom dimensions in pixels for exact sizes.
Does cropping reduce image quality?
Cropping alone does not reduce quality — it simply removes pixels outside the selected area. If you resize the cropped area to larger dimensions than the crop, it will introduce blur. The tool crops without resampling for maximum quality.
What image formats does the cropper support?
Supported formats: JPG/JPEG, PNG, GIF, WebP, and BMP. Output is in the same format as your input. For transparent backgrounds, use PNG input to preserve transparency in the crop.
Is my image uploaded to a server when I use this tool?
No. The image is processed entirely in your browser using the HTML5 Canvas API. No image data is transmitted to any server — your photos stay private on your device.
Can I crop images to specific pixel dimensions for social media?
Yes. Common social media dimensions: Facebook cover 851×315, Instagram square 1080×1080, Twitter header 1500×500, LinkedIn cover 1584×396. Enter these exact pixel values in the crop dimension fields.
