WebP is usually smaller than JPG at the same quality, but not always — the real size change is shown for every file, including the rare file that gets bigger. Changing quality re-converts files already added.

    Next: try Image Compressor — Reduce JPG/PNG/WebP size with a quality slider.

    WebP is Google's modern image format: for the same photo at the same quality it is usually 25–35% smaller than JPG. That means faster web pages and quicker uploads. This free JPG to WebP converter turns your JPGs into WebP files in seconds, entirely in your browser, with no uploads.

    Drop in one JPG or a whole batch, choose a quality level, and download WebP files with the real size saving shown for every image. For the smallest files, run the results through the Image Compressor next. PNG originals? Convert them first with the PNG to JPG Converter — or keep them as PNG when transparency matters.

    How to use

    1. Drop JPG files onto the box above, click it to browse, or paste with Ctrl+V. You can add several at once.
    2. Set the WebP quality — 85% is a good balance between size and quality.
    3. Wait while each file converts. Before and after sizes are shown for every file, with the percentage saved.
    4. Download files one by one, or all at once with Download all (ZIP). Use Start over for a new batch.

    JPG vs WebP: what's the difference?

    JPG is the thirty-year-old standard for photographs. It uses lossy compression based on the discrete cosine transform (DCT), splitting the image into 8×8 blocks and discarding fine detail the eye barely notices. It works everywhere, but its compression is showing its age.

    WebP, launched by Google in 2010, uses predictive coding borrowed from video compression to store the same photo in fewer bytes. At the same visual quality, a WebP is typically 25–35% smaller than a JPG. WebP also supports transparency and animation, which JPG cannot do.

    How much smaller will my WebP be?

    Expect 25–35% smaller for a typical photo. Large smooth areas — skies, walls, studio backgrounds — shrink the most, sometimes by half. Very small or heavily compressed JPGs shrink less, and occasionally a WebP comes out slightly bigger; this tool shows the real numbers.

    Where can I use WebP?

    Every modern browser — Chrome, Edge, Firefox, Safari 14 and later — displays WebP, as do current Android and iOS browsers. WordPress, Shopify and most social platforms accept WebP uploads. Only very old software cannot open it, so keep a JPG copy for those cases.

    Frequently asked questions

    How much smaller is WebP than JPG?

    For a typical photo, 25–35% smaller at the same visual quality. Smooth images like skies can shrink by half; tiny or heavily compressed JPGs shrink less. The tool shows the exact before-and-after size for every file.

    Will WebP images work everywhere?

    Yes — Chrome, Edge, Firefox and Safari 14 or later all display WebP, as do current Android and iOS apps. Older desktop programs cannot open WebP, so keep a JPG copy for old software.

    Does converting JPG to WebP lose quality?

    A little. The image has already been compressed once as a JPG, so a second lossy pass softens very fine detail slightly. At quality 85 the difference is invisible on screen for almost every photo.

    What if my browser can't make WebP files?

    Almost every current browser can, but a few older ones can display WebP without encoding it. If yours cannot, this tool says so plainly instead of giving you a broken file — update to a recent Chrome, Edge or Firefox and try again.

    Can I convert WebP back to JPG?

    Yes — open the WebP in any modern browser or image editor and save it as JPG. Every lossy conversion discards a little detail, so converting back and forth softens the image. Convert from the best-quality original you have.

    Why did one of my files get bigger as WebP?

    It happens with very small images, where WebP's container overhead outweighs its compression advantage. If a WebP comes out bigger, keep the original JPG.
