JPG to WebP Converter

The converter is preset for JPG pictures leaving as WebP. If you are preparing images for a website, read the next section before pressing the button, because resizing first matters more than the format.

1. Drag JPG or JPEG files onto the box, paste them, or click to browse. Photo sets of any reasonable size can be added together.
2. Check that Convert to shows WebP; it is already chosen.
3. Set Quality. A value of 75 to 80 is a sensible starting point for photographs.
4. Press Convert images and wait for the thumbnails to appear.
5. Compare the sizes, then download each file or press Download all.

Format is only one of the things that makes a picture heavy. For a page, this order of work tends to pay off most:

• Resize first. A 4000 pixel wide photo shown in a column 800 pixels wide carries 25 times more pixels than needed. Cut it down with the image resizer, then convert.
• Convert once. Run the resized JPG through this page at 75 to 80.
• Compare. Check the saving in the results list and look at a photo or two at full size.
• Keep the JPG originals. They are your master copies.

For a feel of the numbers, imagine a gallery of 12 photos at 450 KB each, which is 5,400 KB or about 5.3 MB. If WebP trims 25 to 35 percent from each, which is a plausible range though it varies by picture, the gallery falls to roughly 3.5 to 4 MB. That saving is the same for every visitor on every visit, which adds up on mobile connections.

If you also want to cut the size within the same format, the Compress JPG page works on quality and width without changing JPG into anything else.

JPG and lossy WebP both discard information. Passing a JPG through a WebP encoder therefore adds a second layer of loss on top of the first. At sensible settings the damage is hard to see, but it accumulates if you keep converting back and forth, so convert once from the highest-quality original you have and avoid round trips.

Other points to keep in mind:

• Location and camera details in the JPG are not copied into the WebP. If privacy is the main aim, the dedicated EXIF data remover reports exactly what was found.
• Color profiles are dropped, so photos in wide color spaces may look slightly different in color-managed software.
• Browsers show WebP reliably today, but some older apps do not. Keep a JPG fallback if your images are also emailed or printed.
• A browser that cannot encode WebP may return a PNG. If the result does not end in .webp, try a different browser.

Graphics with transparency are covered on the PNG to WebP page. The whole process takes place on your device, so unpublished product photos and client work are never uploaded.

A few minutes of checking prevents surprises after a batch goes live:

• Look at the hero image at full size. The largest picture on a page shows flaws first, so judge the quality on that one.
• Test on a phone. Open the page on a real device. Most visitors will see the image there, and a small screen forgives more than a large monitor.
• Check the file names and endings. Each result should end in .webp. A different ending means your browser could not encode WebP.
• Confirm your platform accepts WebP. Most current site builders and content systems do, but some plugins and older themes still restrict uploads to JPG and PNG.

If you build pages by hand, the picture element lets a page offer a WebP file and a JPG fallback together, so visitors with an unusual browser still see the photo. Whatever you publish, the JPG originals stay safely on your device.
