Image Converter: how to use it

  1. Drop in the image you want to convert.
  2. Choose Convert to: PNG, JPEG, WebP or AVIF.
  3. For JPEG, WebP and AVIF, set the Quality. 90 keeps nearly all the detail. Then download.

Tips

  • Transparent areas turn white in JPEG, because JPEG has no transparency. Keep logos and cut-outs as PNG or WebP.
  • Not every browser can save AVIF. If yours cannot, you will be told, and WebP is a good alternative.
  • The image formats guide explains which format suits photos, screenshots and graphics.

Image Converter: what it does and when to use it

The converter decodes your image in the browser and writes it out again as PNG, JPEG, WebP or AVIF. Changing format does not improve a picture: converting a small, blocky JPEG to PNG gives you a bigger file with the same blocks. What the right format does is match the job, which is where most file-size and compatibility problems come from.

WebP is the practical default for websites: smaller than JPEG at the same visual quality and supported by every current browser. JPEG is the safe choice for anything old, such as email clients and office software. PNG is for transparency and for flat graphics like logos, charts and screenshots with text, where JPEG leaves smudges around edges. AVIF is smaller again, but slower to write and not every browser can write it yet; where yours cannot, you get a PNG and the downloaded file name shows it.

Transparency needs care: JPEG has none, so transparent areas become white when you convert to it. For iPhone photos, the dedicated HEIC to JPG converter handles the HEIC format, and our image formats guide goes through each format in more depth.

Image Converter: frequently asked questions

Is the Image Converter free, and do I need to sign up?

Yes, the Image Converter is 100% free with no sign-up, no login and no account. The Image Converter runs in your browser, so it has no daily limit and no upload, and saves at full size with no watermark. See why it is free.

Which format should I choose?

WebP for the web, because it is smaller than both JPEG and PNG and every current browser reads it. JPEG when compatibility with older software matters. PNG when you need transparency or crisp flat graphics such as logos and screenshots. AVIF when size matters more than encoding speed.

Why did my transparency turn white?

JPEG has no alpha channel. When converting anything transparent to JPEG the transparent areas have to become a solid colour, and white is the conventional choice. Convert to PNG or WebP instead if the transparency matters.

How do I convert WebP to JPG or PNG?

Open the WebP file, choose JPG or PNG and download. Choose PNG if the image has a transparent background, since JPG turns transparency white. Our image formats guide explains when to use each format.

How do I convert PNG to JPG without losing quality?

Use a high quality setting, around 90, and the difference is invisible for photos. JPG is lossy, so a small amount of detail is always lost, but the file is usually much smaller. For screenshots and logos with sharp text, PNG or WebP stays crisper.

Can I convert iPhone HEIC photos here?

Use the HEIC to JPG converter, which includes the decoder HEIC files need. Most browsers cannot open HEIC by themselves.
