Image format guide:
PNG – Lossless compression. Best for barcodes, QR codes, logos, and images with sharp edges or transparency. Larger file size but maximum clarity.
JPEG (JPG) – Lossy compression. Good for photos and complex images with gradients. Smaller files, but not ideal for barcodes or text due to compression artifacts.
WebP – Modern format with superior compression. Supports both lossy and lossless modes, often producing smaller files than PNG or JPEG at similar quality. Good general-purpose choice.
SVG – Vector format (not pixel-based). Infinitely scalable with no quality loss. Ideal for QR codes, logos, and graphics that need to resize perfectly. Very small file size for simple graphics.
