When to use JPG — and when not to
JPG is the right format for photographs. Its lossy compression works with how eyes perceive colour gradients — you lose some data, but the result looks nearly identical to the original at sensible quality settings. A 5 MB RAW photo becomes a 500 KB JPG that looks the same on screen. That trade-off makes JPG the standard for email attachments, social media uploads, and web content where bandwidth matters.
JPG is the wrong format for screenshots, logos, text-heavy graphics, and anything requiring a transparent background. These have sharp edges and flat colour blocks — exactly where JPEG compression creates visible artefacts (blocky edges, colour banding). Use PNG for those instead.
Common conversions: HEIC to JPG makes iPhone photos usable on Windows and web platforms. WebP to JPG extracts images from Google Search or web pages in a format every app accepts. PNG to JPG shrinks file size when transparency is no longer needed. PDF to JPG turns document pages into shareable images.
