Clean file naming works alongside broader web performance optimization strategies. A descriptive name helps search engines understand the image, but oversized files degrade Core Web Vitals metrics like Largest Contentful Paint (LCP). Apply aggressive lossy or lossless image compression to keep JPG files under 150 to 200 KB whenever possible without sacrificing visual sharpness.

Never confuse image file names with accessibility markup. The HTML alt attribute exists to provide context for screen readers used by visually impaired visitors, as well as fallback text if an asset fails to download. Alt text should read as an articulate, grammatically correct sentence describing the image context.

Avoid keyword stuffing in filenames. Stuffing an image with awkward phrasing like cheap-shoes-best-running-shoes-discount-running-shoe.jpg triggers algorithmic spam flags. Use natural descriptors. Name the file brooks-ghost-running-shoes-profile.jpg, and write the corresponding alt text naturally: alt="Side profile view of Brooks Ghost running shoes on track pavement." This division of labor keeps your file systems readable while delivering context to crawlers and users alike.
