PNG to WebP Details
When something needs WebP instead of PNG, PNG to WebP keeps every step on one screen: upload, queue, convert, download.
PNG is a lossless raster format with a real alpha channel, so repeated saves never degrade the picture. WebP is the modern web format built to undercut both JPG and PNG at the same visual quality.
Step by step
The order below follows the page itself, and no step asks you to sign up or confirm anything.
- Drag your PNG files onto the upload area, or click it and pick them from the file dialog.
- Files line up in the queue as you add them. The ceiling is 20 files, so run a second round for more.
- The convert button rewrites the selected file as WebP; the batch button repeats that for every PNG file in the queue.
- Rename the output in the queue field before downloading; the extension is set to WebP for you.
- Click the download link on the finished row and the WebP file lands on your device.
Formats, limits and behaviour
The limits match what the interface shows, and the processing behaves like this:
- Accepted input: PNG (png), up to 24 MB per file.
- The result is written as WebP and encoded at quality 90.
- The queue carries 20 files at a time, and each file travels in its own request.
- Transparent pixels survive the trip because WebP supports an alpha channel.
- PNG is lossless while WebP is encoded with loss, so hard lines and small text can soften slightly at the edges.
- Do not count on metadata surviving: whether EXIF and ICC data travel depends on the engine handling the file, so keep anything critical elsewhere.
When to choose this tool
This conversion earns its place when an existing PNG file has to land somewhere that asks for WebP. Site imagery, blog covers and any page where weight matters are the natural home for WebP. It carries alpha and opens in every current browser, though some older desktop apps still refuse it. PNG is a lossless raster format with a real alpha channel, so repeated saves never degrade the picture.
WebP is the balanced answer between size and compatibility. Go to AVIF output for smaller files, or JPG output for the widest reach.
Quick tips
- Filling the queue with 20 files and hitting convert all is faster than working through them one by one.
- Renaming outputs in the queue keeps your downloads folder readable once several WebP files land there.
- WebP is encoded with loss, so converting the same file repeatedly costs quality. Keep the original.
- Test one file, judge the result, then send the rest of the PNG files through in a batch.
Data and privacy
Processing an image means uploading it, and that upload lives only as long as the request. Once the output exists, the file is not stored and never handed to a third party. Ads may appear on the page, but no ad network can reach your upload.
