Image to WebP Converter

WebP is an image format designed to provide efficient compression for web graphics and photographs. Depending on the original file, image content, and quality settings, converting to WebP can reduce file size while maintaining good visual quality.
Whether you are preparing images for a website, blog, online store, or social media project, this tool makes it easier to convert supported image files into the WebP format.
How to Use the Image to WebP Converter
Follow these simple steps to convert your images.
1. Upload One or Multiple Images
Select images from your device or drag and drop them into the upload area. You can select several files in one action, making bulk image conversion more convenient.
The tool supports JPG, JPEG, PNG, GIF, BMP, and WebP files when your browser can decode them. Each uploaded image must be 10 MB or smaller.
2. Adjust the WebP Quality
Use the quality slider to control the balance between file size and visual quality. A lower setting generally creates smaller files, while a higher setting usually preserves more image detail.
Start with 80% quality and review the converted result. If an image contains fine details, text, or sharp edges, compare different settings before using it on your website.
The best setting depends on the image. A photograph may compress differently from a logo, illustration, or screenshot.
3. Resize Images If Needed
You can optionally enter a maximum width in pixels. The converter scales the image proportionally to maintain its aspect ratio and does not enlarge images beyond their original width.
Leave the field blank if you want to preserve the original dimensions.
4. Convert and Review Your Images
Click Convert All Images to process the files in your list. Each result shows the original file size, converted WebP size, dimensions, and conversion status.
Use the preview to compare the original image with the converted version. Check that the result looks clear enough for its intended use.
5. Download Your WebP Files
Download individual converted images using their respective buttons, or choose Download All Converted to request downloads for all completed images.
Your browser may require permission for multiple downloads. If it blocks them, allow multiple downloads for the website or download the files individually.
What Is the WebP Image Format?
WebP is an image format developed by Google for use on the web. It supports both lossy and lossless compression, as well as transparency. It can be useful for photographs, graphics, logos, and other web images.
The main benefit is efficient image delivery. Smaller image files can reduce the amount of data a browser needs to download, which may help pages load faster when images are a significant part of the page weight.
However, WebP conversion does not guarantee a smaller file in every case. A highly optimized source image may already be smaller than its WebP version at a particular quality setting. Always compare the output size and visual quality before replacing an original image.
Benefits of Converting Images to WebP
Reduce Image File Sizes
WebP can produce smaller files than some traditional image formats, depending on the source and compression settings. This can be useful when preparing multiple images for websites or online stores.
Prepare Images for Websites
Converting large collections of supported images can help streamline an image optimization workflow. Smaller image assets may reduce page weight, although actual page performance also depends on hosting, caching, image dimensions, and other resources.
Process Multiple Images Together
Bulk conversion saves time when you have several product photos, blog images, or website graphics. Instead of repeating the upload process for every file, select multiple images and convert them in one session.
Keep Transparency Where Supported
WebP supports transparency, so transparent PNG graphics can generally be converted without adding an unwanted solid background. Review the result before publishing, especially when working with logos and interface graphics.
Does WebP Conversion Reduce Image Quality?
It depends on the conversion settings. Lossy WebP compression can reduce file size by discarding some image information, which may introduce visible changes at lower quality settings. Lossless WebP preserves the image information but may produce larger files.
This browser-based converter uses a quality setting when generating WebP output. For most everyday photographs, a setting around 75–85% is a reasonable starting point, but it is not a universal recommendation.
Logos, screenshots, and images containing small text may need more careful review. Keep an original copy of important images so you can compare results or convert them again with different settings.
Is This Image to WebP Converter Free?
Yes. CornerCopy’s image to WebP converter is designed for free browser-based use. You can upload multiple supported images, change quality settings, optionally limit image width, preview results, and download converted files without a paid API.
The tool uses your browser’s image decoding and Canvas features to generate WebP files. Images are processed locally rather than uploaded to a conversion server. Browser compatibility and available memory can affect which files can be processed successfully.
Animated GIFs are converted into still images; the original animation is not retained. Large batches can also use substantial memory, so processing smaller groups may be preferable on devices with limited resources.
Frequently Asked Questions
How do I convert JPG to WebP?
Upload your JPG image, choose a quality setting, and click Convert All Images. When conversion finishes, download the resulting WebP file.
Can I convert PNG to WebP without losing transparency?
Yes. WebP supports transparency, and the browser-based conversion process can preserve transparent areas. Review the converted image to ensure it looks correct.
Can I convert multiple images to WebP at once?
Yes. Select multiple supported files or drag and drop them into the upload area. The tool processes them in sequence and provides an individual download button for each converted image.
Is there a file size limit?
This tool accepts files up to 10 MB each. Browser memory and device performance may limit how many large images you can process comfortably in one batch.
Will converting an image to WebP always reduce its size?
No. The result depends on the source format, original compression, image content, dimensions, and chosen quality. Compare the original and converted sizes before using the output.
Can I convert animated GIFs to WebP with this tool?
The tool can convert supported GIF images, but it produces a still image rather than preserving animation. Use an animation-aware converter if you need to retain moving frames.
Do I need an API key?
No. The tool uses browser-based image processing and does not require a paid conversion API.
