How it works

  1. Drop your files in the zone above (or click it, or paste with Ctrl+V).
  2. They convert instantly, right in your browser — nothing is uploaded.
  3. Adjust quality or max width if needed; files reconvert automatically.
  4. Download files one by one, or everything at once as a ZIP.

About the formats

PNG

PNG is the standard lossless format: perfect quality, full transparency support, and universal compatibility. Its weakness is size — photographs saved as PNG are often 5–10× heavier than a visually identical JPG or WebP.

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.

Frequently asked questions

Will I lose transparency when converting from PNG?

Converting to WebP keeps transparency. Converting to JPG replaces transparent areas with a white background, because JPG has no alpha channel — that's a limit of the format, not of this tool.

Why convert to WebP?

WebP gives the same visual quality as JPG or PNG at roughly 25–35% smaller file size, supports transparency, and is read by every modern browser — the best choice for fast-loading websites.

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.
