Image Converter
The right image format depends entirely on the picture. A photograph saved as PNG can be five times larger than the same image as a well-tuned JPEG, while a logo with sharp edges saved as JPEG picks up ugly artefacts around the lines. WebP usually beats both on file size, which matters because images are typically the heaviest part of a web page and the main reason it feels slow on a phone.
This converter changes an image from one format to another in your browser. It is useful when a website only accepts certain file types, when a client sends assets in a format your tool cannot open, or when you want to cut page weight before publishing. Because the conversion happens locally, private photographs and unreleased artwork are never uploaded to a third-party server.
A simple rule covers most decisions: JPEG for photographs, PNG when you need transparency or crisp edges, and WebP when your audience uses modern browsers and you want the smallest file. Convert from your highest quality original rather than from an already compressed copy, since compression damage cannot be undone.

Frequently asked questions
Are my images uploaded?
No. Conversion runs in your browser using the canvas API, so the file never leaves your device.
Will converting reduce quality?
Converting to a lossy format such as JPEG or WebP discards some detail. Converting to PNG is lossless but produces a larger file for photographs.
Does JPEG support transparency?
No. Transparent areas become solid, usually white or black. Use PNG or WebP when transparency matters.
Should I use WebP everywhere?
It is well supported in current browsers and usually smaller, but keep a JPEG or PNG fallback if you must support very old software.
