or click to browse. JPG, PNG, WebP and AVIF, with no size cap. Stays on your computer.

No cap on the file

There is no server bill to protect here, so the only limit is your own device, not a plan tier.

No signup, no watermark

No account, no trial, no upgrade prompt on the download. Ads pay for the site.

Nothing is uploaded

That is why there is no cap and no account. Turn your network off once it starts and it still finishes.

Transparency is kept

PNG, WebP and AVIF keep see-through areas. JPG has nowhere to store them, and the tool says so before you pick it.

How it works

  1. Pick the format you want out: JPG, PNG, WebP or AVIF.
  2. Drop your picture, or click the box to choose a file.
  3. Download the result. The name ends with a short tag, like logo-8f2a1c.webp.

Which format to pick

WebP is the safe default. It is much smaller than PNG, it keeps transparency, and every current browser opens it.

AVIF is smaller again for photos, at the cost of older software that has never heard of it. Some browsers can open an AVIF but cannot write one; when that is the case here, the choice is shown as unavailable instead of handing you a file with the wrong contents.

PNG is lossless, so it is the one for screenshots, logos and anything with hard edges you need kept exact.

JPG is for photos that have to open in something old. It cannot store transparency, so see-through areas come out white.

The pixel width and height never change, whichever format you pick.

Frequently asked questions

Which formats can it change between?

JPG, PNG, WebP and AVIF, in any direction. Formats your browser cannot write are shown as unavailable rather than quietly producing the wrong file.

Does transparency survive?

Yes, for PNG, WebP and AVIF. JPG has no way to store transparency, so see-through areas come out white when you convert to JPG.

Is my picture uploaded to a server?

No. The work happens on your own device. You can switch your network off after it starts and it will still finish.

Does it add a watermark or need an account?

No watermark, no account, no trial, and no upgrade prompt on the download. The site is free and paid for by ads.

Which format should I pick?

WebP is the safe default: small files, transparency, and every current browser reads it. AVIF is smaller again but newer. PNG when you need it exact and lossless. JPG when something old has to open it.
