How It Works
Four steps from a heavy PNG or JPG to a lightweight WebP.
- 1
Upload Image
Drag in your PNG, JPG or JPEG files — one at a time or the whole folder.
- 2
Choose Quality
Pick a compression preset or fine-tune the WebP quality with the slider.
- 3
Convert to WebP
Each image is fully decoded and re-encoded as genuine WebP on the server.
- 4
Download Smaller Image
Grab each file individually, or download the whole batch as one ZIP.
Why Convert to WebP?
WebP was built for the web. It is smaller than JPG and PNG at the same quality, and every modern browser supports it.

Lighter images mean fewer bytes over the wire and pages that render sooner.
Better Core Web Vitals
Largest Contentful Paint improves directly when your hero image shrinks.
Improved page speed

Less bandwidth usage
Lower hosting and CDN bills, and a cheaper experience for mobile visitors.
Modern image format
Supported by Chrome, Firefox, Safari, Edge and every current mobile browser.

Frequently Asked Questions
Answers about WebP conversion, quality and privacy.
WebP is a modern image format developed by Google that supports both lossy and lossless compression, as well as transparency. It produces significantly smaller files than JPG and PNG at comparable visual quality, and it is supported by every major browser including Chrome, Firefox, Safari and Edge.
Converting JPG to WebP typically cuts file size by 25–35% at the same visual quality. Smaller images mean faster page loads, better Core Web Vitals scores (especially Largest Contentful Paint), lower bandwidth bills and a better experience for visitors on mobile data.
At the default quality of 80 the difference is invisible in normal viewing, while the file is far smaller. You control the trade-off with the quality slider: raise it towards 100 for maximum fidelity, or choose Lossless for a pixel-perfect copy with no quality loss at all.
Photographs saved as JPG usually shrink by 25–50%. PNG screenshots, logos and graphics often shrink by 60–90% because WebP compresses flat colour and transparency far more efficiently than PNG. Your exact saving is shown for every image after conversion.
Yes. PNG files are fully supported, including PNGs with transparency. The alpha channel is preserved in the WebP output, so transparent logos and cut-out product photos keep their transparent background.
Yes. Drop as many images as you like into the upload area and convert the whole batch in one go. Each file shows its own progress and saving, and you can download everything together as a single ZIP archive.
No. Your original upload is deleted from the server the instant the WebP version is written. The converted file is held in a private, randomly named folder only long enough for you to download it, then removed automatically. Nothing is shared, indexed or kept.
Yes, it is completely free with no account, no sign-up, no watermark and no daily limit on the number of images you can convert.
