Image converter
Pick the output format and quality. The tool re-encodes the pixels and verifies the produced file signature before enabling the download.
Your files are processed in this browser tab. Nothing is uploaded, stored or logged.
Only used by JPEG and WebP output.
Transparent areas are filled with this colour in JPEG.
After encoding, the tool reads the first bytes of the result and compares them with the signature of the requested format. If they disagree, no download is offered. This is why a renamed file can never pass as a conversion.
JPG, PNG and WebP in any direction the browser can encode. WebP encoding is available in current Chrome, Firefox, Edge and Safari; if it is missing the option is disabled with an explanation.
JPEG for photographs, PNG for screenshots, logos and transparency, WebP when you want small files and the destination accepts it.
No. This converter keeps the pixel width and height. Use the resizer if you also need different dimensions.
Not on this page. HEIC support depends on the operating system, AVIF encoding is not uniform, and SVG can carry script so it is deliberately excluded. Unsupported files are rejected with a clear message.
