PNG vs JPG vs WebP

PNG is useful for screenshots, diagrams, UI captures, logos, and assets that need transparency. It is also safer for repeated editing because the format is lossless.

The tradeoff is file size. Large photographic PNG files are often much heavier than JPG or WebP, so PNG should not be the default for every upload.

JPG is usually the practical choice for photos, blog thumbnails, and product shots on fixed backgrounds. It delivers smaller files by using lossy compression.

The cost is that thin text, crisp UI edges, and transparency do not survive as well. If an image still needs alpha transparency, do not flatten it into JPG too early.

WebP is often the best default for a modern website because it can produce smaller files than JPG while also supporting transparency.

If your workflow targets current browsers and modern CMS stacks, WebP is often the first format to test before falling back to JPG or PNG.
