In-depth image guides

What DPI Actually Means (And Why Resizing Does Not Change It)
A print shop asks for 300 DPI and your file has none of that information. What the number really is, where it lives in the bytes, and when it matters.
PNG vs JPG vs WebP vs AVIF: Picking a Format by Content
Four formats, two different models of a picture. Which suits photos, screenshots, logos and transparency, and why the newest is not automatically the best.
HEIC vs JPG: What Actually Changes When You Convert
HEIC and JPG both discard detail, but not the same detail. What a conversion really costs: a second lossy pass, bit depth, transparency and metadata.
