Frequently asked questions
How do I crop an image to a 1:1 square ratio?
Upload your image, click "Crop Studio" on the file card, and select the "1:1 Square" chip. Drag the handles or frame to position your crop, and click "Apply Crop".
What aspect ratios are supported for cropping?
PixelKit includes 1-click presets for 1:1 (Square), 4:5 (Instagram portrait), 16:9 (YouTube widescreen), 9:16 (TikTok/Reels/Stories), 4:3 (Classic photo), 3:2 (DSLR), and Freeform custom cropping.
Can I crop and compress an image at the same time?
Yes. Once you apply your crop in the Crop Studio, you can choose an output format (JPG, PNG, WebP) and an exact target KB limit (e.g., 50KB or 100KB) in the settings panel.
Does cropping reduce the photo quality?
No. PixelKit extracts the cropped pixel matrix directly from your original image data without extra lossy re-encoding steps before compression.
Is this image cropper completely private?
Yes. The entire crop and canvas framing operation executes inside your local device memory using WebAssembly and Canvas API. Zero images are sent to any remote servers.
