Convert JPG and PNG images to WebP directly in your browser
PixelSmithery makes it easy to convert JPG and PNG images to WebP without uploading your files to a remote server. Choose individual images or process a batch, adjust WebP quality, preserve PNG transparency and optionally add your own watermark — all directly in your browser.
How to convert JPG and PNG to WebP
Choose your JPG, JPEG or PNG images, select the WebP quality you need and click Convert all. You can process multiple images in one batch and download each WebP file individually or together as a ZIP archive. Need a JPG instead? You can also use our PNG to JPG converter for fast browser-based conversion. If your source image is in HEIC or HEIF format, convert it first with the HEIC to JPG & PNG Converter, then continue with WebP conversion.
Why convert images to WebP?
WebP can provide smaller file sizes while maintaining strong visual quality, making it useful for websites, portfolios, online stores and other projects where faster image loading matters. For technical details about compression, transparency and browser support, see MDN’s WebP image format guide. If you later need a standard JPG or PNG copy, you can convert the WebP file back with the WebP to JPG/PNG Converter.
Private browser-based processing
Your source images and optional watermark stay on your device. PixelSmithery performs the conversion locally in your browser, so your files do not need to be uploaded to a conversion server. If you want to inspect image metadata or available provenance signals before or after conversion, use the AI Image Checker.
JPG & PNG to WebP Converter FAQ
What is the PixelSmithery JPG & PNG to WebP Converter?
PixelSmithery is a browser-based image tool that converts JPG, JPEG and PNG images to WebP. You can adjust WebP quality, process multiple images at once, preserve PNG transparency and optionally add a watermark before downloading your converted files.
How do I convert JPG or PNG images to WebP?
Choose or drag your JPG, JPEG or PNG images into the converter, select the WebP quality you want and click Convert all. When processing is complete, you can download each WebP image individually or download the entire batch as a ZIP archive.
Can I add a watermark while converting images to WebP?
Yes. Watermarking is completely optional. You can choose your own PNG, JPG or WebP watermark image, adjust its opacity and control how it is placed on the final image. PixelSmithery also provides Custom, Fit and Cover watermark modes for different types of branding and image protection. This makes it useful for adding a small logo, creating a full-size overlay or applying consistent branding across an entire batch of images.
Are my images and watermark uploaded to a server?
No. Your source images and watermark stay on your device. Image conversion and watermark processing are performed locally in your browser, so PixelSmithery does not need to upload your files to a remote conversion server.
Is PNG transparency preserved when converting to WebP?
Yes. Transparent areas in PNG images remain transparent in the resulting WebP file. JPG and JPEG images do not contain transparency, so they remain opaque after conversion.
Can I convert multiple JPG and PNG images at once?
Yes. PixelSmithery supports mixed batches of JPG, JPEG and PNG images. You can process up to 20 images in one batch and download the converted WebP files individually or together in a ZIP archive.
Does WebP quality affect file size?
Yes. Higher quality settings generally preserve more image detail but can produce larger WebP files. Lower quality settings usually create smaller files. PixelSmithery includes Web, Balanced and High quality presets, as well as a manual quality slider.
Why convert JPG and PNG images to WebP?
WebP can often reduce image file size while maintaining good visual quality. Smaller image files can help websites load faster and reduce bandwidth use, making WebP useful for websites, portfolios, online stores and other web projects.
Why use PixelSmithery for JPG and PNG to WebP conversion?
PixelSmithery combines WebP conversion, batch processing, quality controls, PNG transparency preservation and optional watermarking in one browser-based tool. The processing stays on your device, giving you a practical way to prepare images for the web without unnecessary file uploads.
