Image Converter

PNG, JPEG and WebP both ways, with the saving shown per file.

    An image converter changes a photo from one file format to another, for example PNG into JPEG or JPEG into WebP. This one converts up to 30 photos at once in your browser, shows the size difference for each file, and uploads nothing.

    Which format should I use?

    WebP is the default answer for the web. It is roughly 25 to 35 percent smaller than JPEG at the same visual quality, supports transparency, and every current browser reads it.

    JPEG is the safe choice for photos that need to open anywhere, including old software and print shops. No transparency.

    PNG is for graphics with sharp edges, screenshots, logos and anything that needs transparency. Lossless, so files get large quickly for photographs.

    Typical conversions

    • PNG to WebP or PNG to JPEG: the biggest win. Screenshots saved as PNG often shrink by 80 percent or more.
    • JPEG to WebP: a solid 25 to 35 percent saving for website images.
    • WebP to JPEG: when a tool or printer refuses WebP.
    • HEIC from an iPhone: this tool uses the browser’s built-in codecs, and only Safari decodes HEIC. The HEIC to JPG tool ships its own decoder and works in every browser; bring the JPG here if you need WebP. For photos you have not taken yet, Settings → Camera → Most Compatible on the iPhone writes JPEG directly.

    Quality settings

    For WebP and JPEG the quality slider controls compression. 85 is a good default. Going to 100 roughly doubles the file size for a difference you will not see on screen.

    When converting a transparent PNG to JPEG, transparency has to be replaced by a solid color. Pick that color above, white by default.

    Questions

    Is the conversion lossless?

    Converting to PNG is lossless. WebP and JPEG use lossy compression at the quality you choose. Converting a JPEG to PNG does not restore quality that was already lost.

    Can I convert HEIC files from my iPhone?

    This converter uses the browser's built-in codecs, and Safari is the only current browser that decodes HEIC; the rest reject it. The HEIC to JPG tool carries its own decoder inside the page, so it works in every browser; run the photos through it first, then bring the JPG or PNG here if you need WebP.

    How many files at once?

    Up to 30 per batch. They all use the same settings.

    Does converting reduce quality every time?

    Each lossy re-encode loses a little. Convert from the original whenever possible instead of chaining conversions.
