WebP converter — to and from WebP, free
To convert images to and from WebP for free without uploading anything, open Klipzo, drop in your file, and export as WebP for smaller, faster-loading web images — or convert an existing .webp back to PNG or JPEG. It all runs in your browser on your own device, with no account and no watermark.
WebP typically produces files 25–35% smaller than JPEG or PNG at the same visual quality, which means faster pages and lower bandwidth. Klipzo lets you go both directions: turn a heavy PNG or JPEG into a lightweight WebP for a website or app, or convert a .webp you downloaded into a PNG or JPEG that older software and social uploaders accept. A quality slider on export lets you trade file size against fidelity, and because the encode happens locally on Canvas, even batches of large photos convert instantly with no server round-trip.
How to convert to and from WebP online
- Open the converter Go to Klipzo and drag your image in, or click to browse. A PNG, JPEG, or existing .webp all load instantly on your device.
- Pick the target format Choose WebP to shrink an image for the web, or choose PNG/JPEG to convert an existing WebP into a more widely supported format.
- Set the quality For WebP or JPEG, drag the quality slider to balance file size and sharpness. Watch the estimated output size update as you adjust.
- Preview the result Compare the converted image against the original to confirm the compression level looks right before you save.
- Export and download Click Export to download the converted file. No sign-up, no watermark, and metadata is stripped on the way out.
Tips
- For photos on a website, WebP at around 80% quality is a strong default that cuts file size sharply with little visible loss.
- Converting a transparent PNG? WebP preserves transparency and is far smaller than PNG for the same graphic.
- If a CMS or upload form rejects .webp, convert it to JPEG here first, then upload.
- Run WebP through the Compress tool afterward if you need to hit a specific size budget.
- Keep a copy of the original PNG if you might need to re-edit later, since re-encoding always discards some detail.
Why it’s private
Unlike most “online” editors, Klipzo never uploads your photo. Everything — decoding, editing, and export — happens on your own device inside the browser. There’s no server that receives your file, no account, and no watermark on what you export. See exactly how it works →
Frequently asked questions
Does converting to WebP cost anything?
No. The WebP converter is free with no account, no watermark, and no daily limit. Ads on the surrounding guide pages keep it running, not fees for the tool itself.
Are my images sent to a server to be converted?
Never. Both encoding to WebP and decoding from WebP happen in your browser using the Canvas API, so your files stay on your device the entire time.
Can I convert a WebP back into a JPG or PNG?
Yes. Load any .webp and export it as JPEG or PNG. This is handy when a program or upload form rejects WebP files.
Will WebP look worse than my original JPEG or PNG?
At the same file size WebP usually looks as good or better. You control the trade-off with the quality slider; set it near the top for near-lossless results.
Does WebP support transparency?
Yes. WebP keeps an alpha channel, so a transparent PNG converts to a transparent WebP without a background being added.
