JPG to WebP Converter

This JPG to WebP converter re-encodes JPG and JPEG photos as WebP in your browser, so they load faster on your website. WebP usually gives a smaller file than JPG at the same visual quality, which is why page speed tools suggest it. Drop in one photo or a whole gallery, set the quality with a preset or the exact 1 to 100 slider, and optionally cap the width so oversized camera photos are scaled down at the same time. Each file shows its old and new size, and a batch shows the total saving before you download the ZIP. Nothing is uploaded, so the originals stay on your device. It is a quick step before uploading images to your CMS or a static site.

Bulk supported. Add several files and they are processed in a queue with one ZIP download. The same settings apply to every file, and nothing leaves your device.

How to use

01

Load your JPG photos

Drag .jpg or .jpeg files onto the upload area, choose a folder, or paste a photo with Ctrl+V, up to 50 MB each. A single photo shows a card with its size and dimensions; more files start bulk mode.

02

Choose quality and width

WebP is preselected. Pick High (90), Medium (75) or Low (50), or set an exact value; 75 to 85 suits most photos. Add a Max width such as 1600 to shrink large camera files.

03

Convert and check the saving

Press Convert to WebP. Each file lists its input and output size, a summary shows the total change, and batches download together as converted-webp.zip.

Why JPG to WebP Converter

Choosing a WebP quality for photos

The quality number controls how much detail the encoder may drop. Lower numbers give smaller files and more visible artefacts, such as smudged fine texture and banding in smooth skies. The right setting depends on the photo, so convert one image first, compare the before and after panels, and then run the batch.

Pair the quality with a sensible Max width. A 4000 pixel camera photo shown 1200 pixels wide wastes most of its bytes, and scaling it down usually saves more than any quality change.

Common questions

How much smaller will my JPGs get as WebP?
It depends on the photo and the quality you choose. Google's own comparison reported WebP files 25 to 34 percent smaller than JPG at similar quality, and adding a max width can save far more. The size readout shows the real result for your files.
What quality should I use when converting JPG to WebP?
Start around 80. Between 75 and 85 most photos look the same as the JPG at normal size. Use 90 or more for images with text or fine lines, and 50 to 70 only for small thumbnails.
Do all browsers support WebP images?
Current versions of Chrome, Edge, Firefox and Safari all show WebP. Safari added it in version 14, so very old Apple devices may not. Some email clients and older desktop apps still expect JPG.
Does converting JPG to WebP lose quality twice?
Yes, a little. The JPG was already compressed once, and WebP compresses it again. At quality 80 or above the second loss is hard to see, but avoid converting the same image back and forth between lossy formats.
Can I convert a whole folder of JPGs to WebP at once?
Yes. Select all the files and drop them in together. They are converted one after another in the browser, a summary shows the total saving, and Download all gives you one ZIP.
Does the JPG to WebP converter make lossless WebP?
No. It uses the browser's lossy WebP encoder with the quality you set. The WebP format has a lossless mode, but browsers do not give web pages a reliable way to choose it. For photos, lossy WebP at quality 90 or more is the usual choice anyway, and the compare slider shows whether you can see any change.
Is EXIF data kept when a JPG is converted to WebP?
Not by default. The canvas keeps only pixels, so camera details, date and GPS location are dropped, which is usually what you want for public web images. If you need them, turn on Keep EXIF data and the block is copied into the WebP file.
Can I get PNG or JPG output from the JPG to WebP page?
Yes. Change the Output format to PNG, JPG, GIF, BMP or TIFF before converting, or AVIF where your browser can encode it. The same max size and batch options apply.
