Drag your PNG images into the drop zone or click to select them. This converter works with PNGs from any source. You can add up to 30 files at once for batch processing.
Set WebP Quality

Download images one by one or click 'Download All (ZIP)' to get them in a single archive. Use the 'Compare' feature to view the original PNG next to the WebP before saving.
Frequently Asked Questions About PNG to WebP Conversion
What does it mean to convert PNG to WebP?
Converting PNG to WebP means transforming a PNG image file into the modern WebP format. WebP uses advanced compression techniques to produce smaller files while retaining similar visual quality. Because WebP supports both lossy and lossless compression as well as transparency, it’s often a preferred format for web graphics and performance optimization.
Why should I convert my PNG images to WebP?
WebP typically produces much smaller image files compared to PNG, which helps webpages load faster, reduces bandwidth usage, and can improve SEO and Core Web Vitals performance. Smaller image sizes also make mobile browsing smoother and decrease server storage and delivery costs. Converting PNG to WebP is especially valuable for websites with lots of visual content.
How does this png to webp converter protect my privacy?
This tool runs entirely in your browser, so your PNG files are never uploaded to any server. All processing happens locally on your device, meaning nothing is stored or transmitted—keeping your images private and secure. This local conversion approach eliminates upload delays and network security concerns.
Is this PNG to WebP converter really free to use?
Yes. You can use this png to webp converter without paying, signing up, or installing any software. There are no hidden fees, watermarks, or usage limits—just upload, convert, and download your WebP images as many times as you need.
Does converting PNG to WebP reduce image quality?
That depends on the compression settings you choose. With higher quality settings, the visual difference between the original PNG and the WebP can be nearly imperceptible. WebP supports both lossless and lossy modes, so you can prioritize either quality or file size. Using the Compare feature in this tool helps you preview results before saving.
Will transparency be preserved when I convert PNG to WebP?
Yes. WebP fully supports transparency (alpha channel) in both lossy and lossless modes, so transparent backgrounds and semi‑opaque pixels in your PNG images are retained after conversion. This makes WebP ideal for icons, logos, and graphic assets with see‑through areas.
Can I convert multiple PNG files at the same time?
Yes. This png to webp converter supports batch conversion, allowing you to select and convert many PNG files in a single operation. You can then download each WebP individually or use the 'Download All (ZIP)' option for convenience.
Which browsers and devices work with this converter?
The converter works in any modern browser that supports HTML5 file APIs and Canvas, such as Chrome, Firefox, Safari, Edge, and Opera. Because it runs in the browser, you can convert PNG to WebP on desktops, laptops, tablets, or phones without installing apps.
Are WebP images supported everywhere on the web?
Most modern browsers and content delivery networks support WebP images, which means WebP files generally display correctly for the majority of users. For older browsers that don’t support WebP, developers often provide fallback PNG or JPEG images using HTML techniques to ensure compatibility for all visitors.
What should I do if my WebP file ends up larger than the original PNG?
In some cases, especially with very simple graphics or when using high or lossless quality settings, a WebP file can be larger than the source PNG. If your goal is size reduction, lowering the quality slider slightly usually produces a smaller WebP while keeping acceptable appearance. It’s worth testing a few settings to find the best balance.
Can I convert other formats besides PNG to WebP?
This specific tool focuses on converting PNG images to WebP. If you need to convert other formats (such as JPG, GIF, or SVG) to WebP or back, you can often find dedicated online converters that handle those formats—just search for the specific conversion you need.
Will metadata like EXIF data be preserved after conversion?
WebP conversion tools typically focus on the image pixels themselves. Metadata such as EXIF, color profiles, or tags may not always be preserved when converting PNG to WebP. If keeping metadata is important, consider using a dedicated desktop image tool that supports metadata retention.
