How it works
- Drop your files in the zone above (or click it, or paste with Ctrl+V).
- They convert instantly, right in your browser — nothing is uploaded.
- Adjust quality or max width if needed; files reconvert automatically.
- Download files one by one, or everything at once as a ZIP.
About the formats
WebP
WebP is Google's image format for the web, offering smaller files than JPG and PNG with both lossy and lossless modes plus transparency. Browsers handle it well, but plenty of desktop software, older tools and upload forms still reject it — which is why images saved from the web often need converting.
JPG
JPG (JPEG) is the most widely supported image format ever made — every camera, phone, program and website accepts it. It compresses photos efficiently but doesn't support transparency, and each re-save at low quality degrades the image a little more.
What this conversion actually gives
Measured with the converter on this page, on a 2016 × 1512 px test image: the WebP file weighs 470 KB.
| Setting | Result | Change |
|---|---|---|
| Quality 85 % (default) | 553 KB | +18 % |
| Quality 60 % | 255 KB | −46 % |
| Max width 1600 px, quality 85 % | 324 KB | −31 % |
Converting to JPG makes the file bigger here (+18 %): WebP relies on a newer, more efficient codec than JPG: at comparable quality, JPG simply needs more room.
For an email attachment, quality 60 % brings it down to 255 KB. Capping the width at 1600 px gives 324 KB — plenty for any screen.
- Transparent areas become white: JPG has no transparency.
- An animated WebP loses its animation — the first frame is kept.
Your own files will differ — a photo full of detail compresses less well than a flat graphic. These figures come from one reproducible test image, not from an average.
Frequently asked questions
How big will my JPG file be?
On our 2016 × 1512 px test image, a WebP of 470 KB comes out at 553 KB at the default quality (+18 %). Lower the quality slider or set a maximum width and the figure drops further — the page shows the new size as soon as the file is reconverted.
Why do images I save from websites end up as WebP?
Sites serve WebP because it loads faster. Your browser saves whatever the site delivered. Converting the file afterwards gives you a JPG or PNG that any program accepts.
Does converting to JPG reduce image quality?
JPG uses lossy compression, but at a high quality setting the difference is invisible to the eye — and the file gets much smaller, ideal for photos and sharing. Pixloc lets you set the quality with a slider and adds a white background, since JPG has no transparency.
Are my files really private?
Yes. The conversion runs entirely in your browser using its built-in image engine. Your files are never uploaded, stored or seen by any server — you can even disconnect from the internet after the page loads and keep converting.
Is this free? Is there a file limit?
Completely free, no account, no watermark. Convert as many files as you like, up to 200 MB each — the only limit is your device's memory.
Can I convert many files at once?
Yes — drop a whole batch at once. Each file converts independently and you can grab everything in a single ZIP when done.
