Convert JPG to WebP Online, Free
The Tools Kit’s free JPG to WebP converter turns a .jpg or .jpeg photo into a WebP image directly in your browser. The picture is never uploaded: it is decoded, redrawn on a canvas at its original width and height, and re-encoded as WebP at a quality of 0.92, then offered as a download under the same file name with a .webp extension.
People convert JPEG to WebP mainly for websites. WebP usually stores the same photo in fewer bytes, so pages load faster and use less bandwidth, while every current major browser can display it. There is no signup, no watermark and no daily limit.
How to Convert JPG to WebP
- 1
Upload your JPG
Click the upload area or drag a .jpg or .jpeg file onto it. One image is converted at a time.
- 2
Keep WebP selected
WebP is already chosen under "Convert to". You can switch to JPG or PNG with the same buttons if you need a different format.
- 3
Click Convert Image
The photo is drawn onto a canvas in your browser at its original pixel dimensions and re-encoded as WebP at a quality of 0.92.
- 4
Download the WebP file
Check the preview, then click Download. The file keeps its original name with a .webp extension, so holiday.jpg becomes holiday.webp.
The upload box also accepts PNG, GIF, BMP and WebP files, because the same engine powers the Image Format Converter. For transparent graphics, the dedicated PNG to WebP converter is the better starting point.
JPG vs WebP: Which Format Is Better?
JPG has been the default format for photographs for decades and opens in practically any program. WebP is a newer format from Google that compresses photos more efficiently, and it also supports transparency and animation, which JPG cannot. Google’s own comparison puts lossy WebP files at roughly 25% to 34% smaller than JPEG at comparable visual quality.
- Choose WebP for images on a website, blog, online store or web app, where smaller files speed up page loads and help Core Web Vitals such as Largest Contentful Paint.
- Keep JPG for printing, email attachments, older desktop software, and anywhere you are not sure the recipient can open WebP.
- Keep both when in doubt: publish the WebP and archive the original JPG.
If you need to go the other way later, the WebP to JPG converter turns a WebP back into a JPG for software that does not support it.
Will WebP Always Be Smaller Than the JPG?
Usually, but not always. A JPG is already lossy, so converting it means decoding the compressed photo and compressing it again. This converter always encodes at a quality of 0.92, a high setting chosen to keep visible changes to a minimum. A photo straight from a camera or phone, saved at high JPG quality, will normally shrink. A JPG that was already exported at low quality may come out about the same size or even larger, because 0.92 is spending bytes preserving its existing compression artifacts.
Compare the two file sizes before you replace anything. To push the WebP smaller, run it through the Image Compressor, which lets you lower the quality with a slider or aim for a target size. Oversized dimensions matter more than format: a 4000-pixel-wide photo shown in an 800-pixel column wastes most of its bytes, so shrink it with the Image Resizer before converting.
What Changes and What Stays the Same
- Dimensions: unchanged. A 1920 × 1080 JPG becomes a 1920 × 1080 WebP.
- Quality: lossy WebP at a fixed 0.92; there is no quality slider in this tool.
- File name: kept, with the extension switched to .webp.
- Metadata: EXIF details such as camera model, date and GPS location are not carried into the WebP. If you only want to strip metadata and keep the JPG format, use the EXIF Remover.
- Browser support for encoding: the WebP file is produced by your browser’s canvas encoder. Chrome, Edge and Firefox encode WebP; a browser without a WebP encoder, such as Safari, returns PNG data instead, so convert in one of those browsers if the result is not a true WebP.
Common uses
- Converting product photos to WebP to speed up an online store
- Preparing blog and article images for a CMS or site builder that recommends WebP
- Fixing a “serve images in next-gen formats” suggestion from a page speed audit
- Shrinking a hero or banner photo that slows down the first screen of a page
- Converting a photo privately without sending it to an online service

JPG to WebP terms explained
| Term | What it means here |
|---|---|
| JPG / JPEG | A lossy photo format from the early 1990s; .jpg and .jpeg are the same format with different extensions |
| WebP | An image format developed by Google that supports lossy and lossless compression, transparency and animation |
| Lossy compression | Discards detail the eye is unlikely to notice to make the file smaller; this converter encodes WebP lossily at quality 0.92 |
| Quality setting | A 0-1 value that trades file size against detail; higher keeps more detail and produces a larger file |
| Generation loss | The small extra loss that happens each time an already lossy image is decoded and compressed again |
| EXIF metadata | Camera model, date and sometimes GPS location stored inside a photo; not copied into the converted WebP |
Frequently Asked Questions
Upload the JPG, leave WebP selected under "Convert to", click Convert Image, then click Download. The file is converted in your browser and saved with the same name and a .webp extension.
Yes. It is free, needs no account or signup, and has no daily conversion limit.
No. The JPG is decoded, drawn on an HTML canvas and re-encoded as WebP entirely in your browser. The image never leaves your device.
Usually, because WebP compresses photos more efficiently than JPG; Google reports lossy WebP files about 25% to 34% smaller than JPEG at comparable quality. It is not guaranteed for every file: a JPG that was already saved at low quality can come out similar in size or larger at this tool's fixed 0.92 quality, so compare the two before replacing the original.
A little. The WebP is encoded with lossy compression at a quality of 0.92, which keeps visible changes minimal but is not pixel-identical to the JPG. Converting also cannot restore detail that the original JPG compression already removed.
Not in this converter; WebP output always uses a quality of 0.92. To make the WebP smaller, run it through the Image Compressor afterwards, which has a quality slider and a target-size mode.
No. The WebP has exactly the same width and height in pixels as the JPG you upload. Only the file size in bytes changes. Use the Image Resizer first if you also need smaller dimensions.
No. The converter handles one image at a time. Convert each photo, download it, then upload the next one.
No. Redrawing the photo on a canvas does not carry camera details, timestamps or GPS location into the WebP file, so the converted image does not include that metadata.
All current versions of Chrome, Edge, Firefox, Safari and Opera display WebP, as do Android and iOS. Some older desktop software and print services still expect JPG, so keep your original JPG as a backup.
Encoding to WebP depends on your browser's built-in canvas encoder. Chrome, Edge and Firefox encode WebP; a browser without a WebP encoder, such as Safari, returns PNG data instead. If that happens, run the conversion in Chrome, Edge or Firefox.
None. JPG and JPEG are two extensions for the same format, so .jpg and .jpeg files both convert to WebP the same way.

How do you convert JPG to WebP?
To convert a JPG to WebP, upload the .jpg file, keep WebP selected as the target, click Convert Image, and download the .webp. The photo is re-encoded in your browser at 92% quality; WebP files are about 25% to 34% smaller than JPEG at equal visual quality, which is why web pages prefer them.
Is WebP better than JPG for websites?
For web delivery, yes: WebP produces files roughly 25% to 34% smaller than JPEG at the same visual quality, supports transparency, and is displayed by every current browser, so pages load faster and score better on Core Web Vitals. Keep the JPG original for printing or for sending to people using older software that cannot open WebP.
