When JPG is the right format

JPG is the best format for photographs and images with continuous tones - portraits, landscapes, product photos, and any image where colour varies smoothly across the frame. It is universally supported: every device, browser, email client, printer, and social media platform accepts JPG without any compatibility concerns. If you need to share a photo with someone and you are unsure what format they can open, JPG is the safest choice.

JPG is not ideal for screenshots, logos, charts, or anything with large blocks of flat colour or sharp text. For those, PNG or WebP produces sharper results at smaller file sizes because its compression is tuned for different content types.

Why the output files are smaller

Most browser-based image tools prioritise speed over efficiency and produce larger-than-necessary files. This tool uses advanced JPEG encoding that produces files 10-30% smaller than a standard browser-based converter at the same quality level. You get the same image with fewer bytes, which is especially noticeable on photos with complex detail.

Transparency and JPG

JPG does not support transparency. If you convert a PNG or WebP with a transparent background, the transparent areas are replaced with white before encoding. This is the correct behaviour for most use cases - a product photo or profile image with a transparent background will display with a white background in JPG form, which is what most surfaces expect. If you need to preserve transparency, use PNG or WebP instead.
