JPEG to WebP
- Input
- 820 KB JPEG at quality 85%
- Output
- About 550 KB
WebP's compression is more efficient than JPEG's, so the same visual quality needs fewer bytes.
WebP Converter
WebP is an image format that produces smaller files than JPEG and PNG at the same visual quality, typically 25–35% smaller. Every current browser supports it. Convert images to WebP to speed up a website, or convert WebP back to JPG or PNG when older software cannot open it.
Runs entirely in your browser — your images are never uploaded.

How to use the WebP Converter
- 1
Add images
Drop in JPG, PNG or WebP files — the direction is set by the output format you choose.
- 2
Choose the direction
Convert to WebP to save space, or from WebP to JPG or PNG for compatibility.
- 3
Set the quality
80–85% is usually indistinguishable from the original at a much smaller size.
- 4
Download
Save individually or as a ZIP.
Examples
WebP Converter examples
Transparent PNG to WebP
- Input
- PNG logo with transparency
- Output
- Much smaller, transparency intact
Unlike JPEG, WebP has an alpha channel, so it can replace PNG for transparent graphics as well as photos.
WebP back to PNG
- Input
- WebP file, output PNG
- Output
- Larger file that older software can open
Some desktop applications still cannot read WebP. Converting back restores compatibility at the cost of size.
Why use it
What the WebP Converter gives you
Works in both directions
Convert to WebP for the web, or back to JPG and PNG when a program cannot open a WebP file.
Transparency survives
WebP keeps the alpha channel, so transparent PNGs convert without a background being forced behind them.
Real size comparison
Every file shows its before and after size, so the benefit is visible rather than assumed.
Batch processing
Convert a whole folder at once and download the results as a ZIP.
Nothing uploaded
Conversion happens in your browser with no server involved.
Good to know
WebP Converter limitations
- Converting a JPEG to WebP re-encodes it, so a little quality is lost. Convert from the original where possible.
- Animated WebP is flattened to its first frame.
- A few older desktop applications still cannot open WebP files.
- Images are limited to 25 MB each.
Summary
WebP Converter in short
- WebP files are typically 25–35% smaller than equivalent JPEGs.
- WebP supports transparency, so it can replace PNG as well as JPEG.
- Every current browser displays WebP; some older desktop software does not.
- Conversion runs entirely in your browser.
FAQ
WebP Converter questions
What is WebP?
An image format developed by Google that compresses more efficiently than JPEG and PNG. It supports both lossy and lossless compression plus transparency, which no single older format did.
How much smaller are WebP files?
Usually 25–35% smaller than a JPEG of the same visual quality, and often far smaller than PNG for photographic content. The exact saving depends on the image.
Do all browsers support WebP?
Yes. Chrome, Firefox, Safari and Edge have all supported WebP for years, including on mobile. The remaining gap is older desktop applications rather than browsers.
Does WebP support transparency?
Yes, it has a full alpha channel like PNG. That is why it can replace both JPEG and PNG rather than only one of them.
Why would I convert WebP back to JPG?
Compatibility. Some older photo editors, print services and content systems still reject WebP uploads. Converting back to JPEG or PNG solves it at the cost of a larger file.
Does using WebP help SEO?
Indirectly. Smaller images load faster, and page speed is a ranking signal and a Core Web Vitals factor. The format itself is not a ranking factor.
What quality setting should I use?
80–85% for photographs is usually indistinguishable from the original. Lossless WebP exists for graphics needing pixel accuracy, though it produces much larger files.
Is AVIF better than WebP?
AVIF compresses better still, often 20–30% below WebP. It encodes much more slowly and fewer browsers can create it, so WebP remains the more practical default today.
Is my image sent to a server to make WebP?
No. Your browser decodes the image and re-encodes it as WebP on a canvas. No upload happens, so there is no queue, no size cap beyond your own memory, and no copy on anyone else's server.
