PNG to WebP Converter
To convert PNG to WebP, add your PNG images and press Convert with WebP selected. WebP keeps the transparency of the PNG and is usually much smaller, which makes it a good format for logos, icons and screenshots on websites. The quality slider starts at 100%; lower it for smaller files. Nothing is uploaded: the conversion runs in your browser.
- Free, no sign-up
- Your file never leaves your device
- Up to 50 MB per file
At 100% quality WebP is encoded losslessly: pixels are kept exactly, but the file usually gets larger. Lower the quality to 80–90% to shrink it.
Your file never leaves your device; images are processed in your browser. EXIF and location data are not added to the output.
How to convert PNG to WebP
Add your PNG files
Drag the images onto the upload area or browse for them; you can add several files at once.
Keep WebP as the output
WebP is already selected. For formats with a quality setting the slider starts at 100%; lower it if you want a smaller file.
Convert and download
Press “Convert”. Every file is processed in your browser, and you can download the results one by one or as a ZIP.
What is preserved?
Kept
- The image resolution (pixel dimensions)
- The correct photo orientation (EXIF orientation is applied)
- Colors (adapted to sRGB)
- Transparency (alpha channel)
Changed
- WebP is a lossy format: lower quality means a smaller file but less fine detail
- The lossless source is recompressed at the quality you choose, so pixel values are no longer identical
Not carried over
- EXIF, location and camera data: left out of the output for privacy
When to use it
Lighter logos and UI images
Web graphics often ship as PNG. Converting them to WebP keeps the transparent background while reducing the download size, particularly for large illustrations and screenshots.
Reduce an image-heavy page
Replacing a set of large PNG screenshots with WebP versions can cut the weight of a documentation or blog page significantly.
Limitations to know
- Up to 50 MB per file; the output can be at most 16,384 pixels on one side.
- On iPhone and iPad, images above roughly 16 megapixels may not be processed because of a browser limit.
About the formats
What is PNG?
PNG stores pixels without loss and supports full transparency, which makes it a good fit for screenshots, logos and graphics with sharp edges or text. The price is size: photographs saved as PNG are usually much larger than the same picture as JPG or WebP. PNG does not store animations.
What is WebP?
WebP is an image format developed by Google for the web. It supports both lossy and lossless compression, transparency and animation, and typically produces smaller files than JPG or PNG at similar quality. All current browsers display WebP, though some older editors and print services cannot open it.
Frequently asked questions
Does WebP keep the transparent background of a PNG?
Yes. WebP supports a full alpha channel, so transparent and semi-transparent areas carry over.
Is the result lossless?
No. WebP here uses lossy compression, so very fine detail and sharp text edges can soften at low quality. At 100% the result stays very close to the original.
How much smaller will the file be?
It depends on the image. Photographs and gradients shrink a lot; flat graphics that PNG already compresses well shrink less. The result bar shows the exact before and after sizes.
Where can I use WebP files?
In all current browsers, most CMS platforms and many apps. If an older program rejects WebP, convert it back to PNG with the WebP to PNG converter.
Is converting PNG to WebP free?
Yes, completely free. There is no account, subscription or watermark; just add your files and convert them.
Are my files uploaded anywhere?
No. Images are processed in your browser and never leave your device, so the waiting time depends on the file size and your device. EXIF and location data are not added to the output.
