Tips for 3840x2160 Images
Ultra-high resolution (3840×2160) at 8.3 megapixels, these images typically produce files of 10–50 MB or larger. They are designed for 4K displays, digital signage, large-format printing, and high-end visual production.
Storage and bandwidth: At this resolution, storage adds up quickly. Use compression after resizing — WebP or AVIF can cut file size by 30–50% with minimal visible quality loss, saving significant disk space and transfer time.
Workflow tip: Edit and color-correct at full resolution, then export compressed copies for web delivery. Keep the uncompressed original as your archive master.
