Frequently Asked Questions
Which aspect ratio presets are available in SizeSnap Crop Image?
SizeSnap includes Freeform (unconstrained), 1:1 Square (Instagram profile / DP), 4:3 Standard Photo, 16:9 Widescreen (YouTube thumbnails / presentations), 3:2 Classic Photo, and 3.5:4.5 (Passport / Official Government ID format).
Can I crop to exact pixel coordinates and dimensions?
Yes. As you drag and resize the crop box, live pixel coordinates and dimensions are calculated based on your original full-resolution image.
Does cropping reduce photo quality or resolution?
No. The cropped region is extracted directly from the full-resolution source image using high-quality Canvas interpolation. No artificial compression is applied unless you adjust the quality slider.
Is my photo uploaded to an external server?
No. All image cropping and processing is performed 100% locally inside your browser using HTML5 Canvas. Your photos never leave your device.
