Convert between PNG, JPG and WebP
The Image Format Converter switches an image between PNG, JPG and WebP so it fits the requirements of the platform, app or website you are working with. Some services only accept certain file types, and different formats also behave differently when it comes to transparency and compression, so having a quick converter on hand saves a lot of back-and-forth.
The converter reads your uploaded file into an image element, draws it onto a hidden canvas, and then asks the browser to export that canvas using a different MIME type. For JPG output, any transparent areas are filled with a solid background colour since JPEG has no transparency channel, while PNG and WebP outputs keep the alpha channel intact wherever the source image already had one.
Web developers convert legacy PNG assets into WebP to shrink page weight, since WebP usually produces smaller files at a similar visual quality. Designers convert screenshots saved as PNG into JPG when a form only accepts that extension. Anyone who receives a WebP image from a website that will not open in older software can convert it back into a universally compatible JPG or PNG.
Choose PNG when your image contains text, sharp lines or transparency that must stay perfectly crisp. Choose JPG for photographs where small file size matters more than pixel-perfect edges. Choose WebP when your target platform supports it, since it often gives the best combination of small size and good quality for both photos and graphics.
Yes, because JPEG does not support transparency, so any transparent pixels are filled with a background colour, which you can choose before converting.
Most modern browsers support WebP well, but some older software and certain print workflows still expect JPG or PNG, so check your destination before relying on WebP.
The current version processes one image at a time to keep the interface simple and predictable, though you can repeat the process quickly for several files in a row.
No, only the file format and compression method change; use the Image Resizer separately if you also need to change the width or height.
