JPG, PNG, or WebP — which format to use.

JPG is a lossy format designed for photographs. It discards detail that is hard to see in order to shrink file size. Use it for camera photos, email attachments, and documents that must open on software that still does not handle WebP well. Repeated re-saving at low quality adds visible blocks. JPG does not support transparency.

PNG is lossless for the pixels it stores. It is the default for screenshots, diagrams, UI, and any image that needs a transparent background. Camera photos saved as PNG are often unnecessarily large. If you only need a smaller photo, convert or compress to JPG or WebP instead of “compressing” a PNG and expecting photograph-level savings.

WebP can be lossy or lossless and usually beats JPG on photographic size at a similar look. Current Chrome, Edge, Firefox, and Safari open it. Use WebP when you control the website or app that will display the file. Avoid it as the only copy you send to a print shop or an older office tool until you confirm they accept it.

Photos for the web: WebP, with JPG as a fallback. Screenshots and sharp text: PNG. Logos with transparency: PNG or lossless WebP. Print or unknown recipients: ask, then use PNG or high-quality JPG. This is guidance, not a guarantee that a given encoder will hit a target kilobyte size.

Convert between JPG, PNG, and WebP with Convert Image. Reduce photographic size with Compress Image — it changes quality, not pixel dimensions. Change width and height with Resize Image. Turn a set of images into one PDF with Images to PDF. Before you email a photo, see Remove EXIF before sharing or use EXIF Cleaner.
