Upload images and click Convert AllSelect "To WebP" to convert PNG/JPG/GIF to WebP, or "From WebP" to convert WebP back to PNG or JPG.
Adjust quality with the slider (80–90 is ideal), then drag & drop or click to upload one or more images.
Click Convert All, then download each result individually or get all files as a ZIP in one click.
WebP Converter processes images entirely in your browser using the HTML5 Canvas API — no file is ever sent to a server. It supports converting PNG, JPG, GIF, and BMP to WebP, and converting WebP images back to PNG or JPG. Batch mode lets you process multiple files at once and download them as a ZIP.
WebP is a modern image format developed by Google. It produces files 25–35% smaller than JPEG at equivalent visual quality, and supports both lossy and lossless compression as well as transparency. All major browsers support it, making it the preferred format for web performance in 2024.
No. All conversion happens locally in your browser using the HTML5 Canvas API. Your images never leave your device — there is no server upload, no cloud processing, and no data retention. This makes the tool safe for converting private or sensitive images.
For most web use cases, 80–90% quality gives the best balance of visual fidelity and file size. Use 90+ for hero images or photography where detail matters. For thumbnails, icons, or secondary images, 70–80% is perfectly fine and yields the smallest files.
The Canvas API renders only the first frame of an animated GIF. Full animated WebP conversion requires specialized libraries not available natively in browsers. For animated GIFs, consider a dedicated conversion tool. Static GIF conversion works correctly.
Yes. WebP supports alpha channel transparency, equivalent to PNG. When you convert a PNG with transparent areas to WebP, the transparency is preserved. Converting transparent images to JPG (lossy) will fill transparent areas with white, since JPG does not support transparency.
There is no hard limit on the number of files. However, processing many large images simultaneously may slow down your browser due to memory constraints. For batches over 50 images, it is recommended to process them in smaller groups for the best performance.
WebP has become the dominant image format on the modern web. Developed by Google and supported in all major browsers since 2020, it offers significantly smaller file sizes than JPEG and PNG without a meaningful loss in visual quality. Converting your image assets to WebP is one of the highest-impact optimizations you can make for web performance.
This tool handles both directions: converting legacy PNG, JPG, GIF, or BMP images into WebP, and converting WebP images back to PNG or JPG for editing in tools that do not yet support the format. Everything runs in your browser — no upload, no server, no account needed.
In real-world testing across a variety of image types, WebP consistently outperforms older formats. A typical 200KB JPEG converts to roughly 130–150KB WebP at equivalent quality. A 500KB PNG often becomes 80–120KB WebP lossless. The savings compound quickly when you have dozens of images on a page — the difference between a 3-second load and a 1.5-second load can come down to format choice alone.
WebP supports both lossy and lossless modes. Lossy WebP (quality 1–99) is comparable to JPEG in visual fidelity but smaller. Lossless WebP is comparable to PNG but with better compression. This tool uses the browser's native lossy encoder via the Canvas API.
Select "To WebP" mode, set your desired quality (80 is a safe default), upload your PNG files by dragging them into the upload zone or clicking to browse, then click "Convert All." Each file is processed sequentially and appears in the results list. Download individually or use "Download All (ZIP)" to grab everything at once.
PNG files with transparency (alpha channel) convert to WebP correctly — the transparency is preserved. If you need transparency in the output, always use WebP (not JPG) as the target format.
Switch to "From WebP" mode, choose your output format (PNG for lossless with transparency support, JPG for smallest file when transparency is not needed), upload your WebP files, and click Convert All. The tool renders each WebP image onto an HTML Canvas and re-encodes it to the target format.
This is useful when you receive WebP screenshots or assets and need to edit them in software like Photoshop or older tools that do not natively open WebP files.
WebP is supported in Chrome, Firefox, Safari (since version 14), Edge, and Opera — covering over 97% of global browser usage as of 2024. For the small percentage of users on very old browsers, it is a best practice to provide a fallback using the HTML <picture> element with a JPEG source as the default. However, for most modern projects, serving WebP only is perfectly acceptable.
When building HTML templates for ThemeForest or similar marketplaces, replacing PNG and JPG assets with WebP can significantly reduce your template's total file size — an important factor for page speed test scores. Use the <picture> element to support both formats gracefully:
Keep in mind that some email clients do not support WebP — for email templates, stick with PNG or JPG. For web templates, WebP is the recommended choice for all photographic and complex imagery.
