How PicEte Resizes to 300x250
Upload any image to PicEte and our tool automatically resizes it to exactly 300x250 pixels. The canvas-based engine handles aspect ratios by centering your image and applying letterboxing if needed to maintain the 300x250 boundary while preserving original proportions. For true 300x250 output without letterboxing, crop your source image to a 6:5 aspect ratio first. All processing happens locally in your browser — no server uploads required.
