JPG, PNG, or WebP: which image format should you use?

An image format is a choice about how pixels are stored. Converting a file does not automatically make it better. Pick the format for the image’s contents and where people will open it.

Photos and sharp graphics behave differently

JPG is widely supported and often compact for photographs. It uses lossy compression and cannot store transparency. PNG keeps sharp edges and transparency well, but a detailed photograph stored as PNG can become large. WebP supports photos and transparent graphics; its size and quality depend on the encoder and settings used by your browser.

For a photo, try the JPG to WebP converter and compare the output with the original. For a transparent logo that needs a PNG-only editor, use WebP to PNG. If a service specifically demands JPG, PNG to JPG places transparent pixels over white. Inspect the result before uploading it.

Do not expect lost detail to return

Converting JPG to PNG does not undo JPG artifacts. Re-encoding a compressed source can introduce another generation of loss. Keep the original and compare small text, hair, gradients, and transparent edges at the size visitors will see. A smaller file is useful only when the visible result remains suitable.

Check the delivered file

Look at the downloaded extension, actual dimensions, file size, and transparency in the receiving application. A browser may not support every export format; our converters report unsupported output rather than silently changing the requested format. Conversion runs locally and does not upload your image through the tool.
