Adjust Quality
Use the quality slider to control the WebP compression level (1–100%). Lower values produce smaller files with more compression. The default of 90% gives an excellent balance for most images.
Convert
Click Convert or Convert All. Each image is processed with a progress spinner on its thumbnail. The conversion happens instantly in your browser — no upload needed.
Download
Download a single converted WebP file directly, or download all converted images as a ZIP archive. Files keep their original names with the extension changed to .webp.
Frequently Asked Questions
What is WebP and why should I use it?
▼
WebP is a modern image format developed by Google that provides superior lossy and lossless compression for web images. It produces files 25-35% smaller than JPEG and up to 26% smaller than PNG at equivalent quality. Google recommends WebP for all web images, and using it improves page speed and SEO rankings.
Does converting to WebP reduce image quality?
▼
WebP uses lossy compression by default, so some imperceptible detail is discarded — similar to JPEG. At quality levels above 75%, the visual difference is virtually undetectable. You can control the trade-off between quality and file size using the quality slider.
Is WebP supported by all browsers?
▼
WebP is supported by all modern browsers: Chrome, Firefox, Edge, Safari (14+), and Opera. The only browsers that don't support it are Internet Explorer and Safari versions before 14. For legacy support, use the HTML <picture> element to serve JPEG/PNG fallbacks.
Does WebP support transparency?
▼
Yes. WebP supports full alpha channel transparency, similar to PNG. When converting a PNG with transparent areas, the transparency is preserved in the WebP output. This makes WebP ideal for logos, icons, and overlays — with much smaller file sizes than PNG.
Is my image uploaded to a server?
▼
No. This tool runs 100% in your browser. Your images never leave your device. The conversion happens locally using your browser's built-in Canvas API. No data is transmitted, no cookies are used, and no third-party services have access to your files.
What is the maximum file size?
▼
Each file can be up to 25 MB, with a total limit of 100 MB across all uploaded files. You can upload up to 10 images at once.
What quality setting should I use?
▼
For photographs and web images, 75-85% is ideal — this provides excellent visual quality with significant file size savings. For screenshots and graphics with text, use 85-95%. For maximum compression where some quality loss is acceptable, try 50-70%.
Can I convert WebP back to JPEG or PNG?
▼
Yes, use our WebP to PNG Converter or Image Converter tool. Keep in mind that converting a lossy WebP to PNG won't restore quality lost during the WebP conversion — it will be a lossless copy of the WebP, not the original.
How much smaller are WebP files?
▼
WebP typically saves 25-35% compared to JPEG at the same visual quality. Compared to PNG, savings are even larger — often 50-80% for photographic images. The exact savings depend on the image content and quality setting.
Will my images be saved if I close the browser?
▼
Yes. Your uploaded images and conversion results are automatically saved in your browser's IndexedDB storage. When you return to this page, everything is restored exactly as you left it. Click Clear All to remove all stored data.

Features Explained
Superior Compression
▼
WebP typically produces files 25-35% smaller than JPEG and up to 26% smaller than PNG at the same visual quality. This means faster page loads, lower bandwidth costs, and better Core Web Vitals scores for your website.
Adjustable Quality
▼
Control the compression level with a quality slider from 1% to 100%. Higher values produce sharper images with larger files. Lower values produce smaller files with more compression artifacts. The default of 90% is optimized for web use.
Transparency Support
▼
Unlike JPEG, WebP supports full alpha channel transparency — similar to PNG but with dramatically smaller file sizes. When converting PNG images with transparency, the transparent areas are preserved in the WebP output.
Multi-Format Input
▼
Convert from JPEG, PNG, BMP, or GIF to WebP. The tool automatically detects the source format and displays it on each thumbnail badge (e.g., 'JPEG → WebP' or 'PNG → WebP') so you always know what was converted.
Batch Processing
▼
Upload and convert up to 10 images at once. Each file is processed individually with its own progress indicator, so you can track the status of every image. All files share the same quality setting.
Drag & Drop Upload
▼
Drag image files directly from your file explorer onto the upload area. You can drop multiple files at once. The tool validates each file and shows an error if a file exceeds the 25 MB size limit or if the maximum of 10 files is reached.
Clipboard Paste
▼
Press Ctrl+V to paste an image directly from your clipboard. This is especially useful for converting screenshots — take a screenshot, paste it into the tool, convert to WebP, and download without ever saving the original file.
File Size Comparison
▼
After conversion, the smart label above the grid shows overall statistics including the total size reduction and percentage savings. This helps you see exactly how much bandwidth WebP saves compared to your original format.
ZIP Download
▼
When converting multiple images, download all results as a single ZIP archive. Each file inside keeps its original name with the extension changed to .webp. For a single image, the download is a direct WebP file.
EXIF Metadata Stripping
▼
Converted images automatically have EXIF metadata (camera settings, GPS coordinates, date, orientation) removed during canvas re-encoding. This protects your privacy when sharing images online.
Auto-Save Progress
▼
Your uploaded images and conversion results are saved automatically in your browser using IndexedDB. If you accidentally close the tab or refresh the page, everything is restored exactly as you left it. Click Clear All to remove all stored data.

Tips for Converting to WebP
Use quality 75-85% for photos
Photographs look virtually identical to the original at these levels but can be 30-50% smaller than the equivalent JPEG. Below 70% you may notice compression artifacts in gradients and skin tones.
Use higher quality for text and graphics
Screenshots, diagrams, and images with sharp text benefit from quality levels of 85-95%. WebP handles sharp edges better than JPEG, but low quality settings can still introduce blurring.
Convert PNG photos to WebP
If you have photographs saved as PNG (common with screenshots and phone exports), converting to WebP can reduce file sizes by 70-90% while maintaining excellent visual quality.
Keep originals for archival
WebP with lossy compression discards some image data. Always keep your original JPEG or PNG files archived. If you need to make edits later, start from the original to avoid compounding quality loss.
Check browser compatibility
WebP is supported by all modern browsers (Chrome, Firefox, Edge, Safari 14+, Opera). For legacy browser support, serve JPEG/PNG fallbacks using the HTML <picture> element.
Use batch mode for site optimization
If you're optimizing an entire website, upload all images at once. Convert All processes every image in a single pass, and Download All packages them into a ZIP for easy deployment.
Compare file sizes
After conversion, check the savings percentage in the smart label. WebP typically saves 25-35% over JPEG and 50-80% over PNG for photos. If savings are minimal, the original may already be well-optimized.
Use for hero images and banners
Large hero images and full-width banners benefit the most from WebP conversion. A 500 KB JPEG hero image might become 350 KB as WebP — saving 150 KB on every single page load.
Convert GIF to WebP for animations
While this tool converts static GIF frames, animated WebP files are significantly smaller than animated GIFs. For animated content, consider using a dedicated animated WebP converter.
Test different quality levels
If file size is critical, try the same image at different quality levels. Convert, check the result, clear, adjust quality, and convert again. Find the sweet spot where quality meets your size target.
