JPEG vs PNG vs WebP
JPEG is best for photos — it compresses well and the quality slider lets you balance file size vs. sharpness. PNG is lossless and ideal for graphics, logos, and images with transparency. WebP offers the best of both: smaller files than JPEG at the same quality, with optional transparency support.
