Convert PNG to JPG

Drop your PNG files below. They are converted on your own device and never sent anywhere.

Convert to JPG when the PNG is a photograph and the file size is a problem. Keep PNG when the image contains text, sharp lines or flat blocks of colour. It is converted by your own browser here, so the file is never uploaded.

Nothing is uploaded. Your files are read by this page and processed by your own processor. Open the Network tab and watch — you will not see them leave.

PNG and JPEG, and why you would move between them

PNG to JPG is the conversion people reach for when a file is too big to attach, too big to upload, or rejected by a form that only accepts JPEG. It usually works dramatically well: a photographic PNG frequently drops by 80–95% with no visible change, because JPEG was designed for exactly that kind of image and PNG was not.

It works badly on the other kind of image. Screenshots, logos, charts and anything with text or hard edges pick up visible smearing around the edges — the classic JPEG "mosquito noise" — and often barely shrink at all. If your PNG is a screenshot, converting it to JPEG makes it look worse without making it much smaller.

Things that catch people out

  • JPEG has no transparency. Anything transparent has to become a solid colour, and the default is white. A logo designed for a dark background will come out with a white box around it.
  • Screenshots and images containing text compress poorly and look noticeably worse. If that is what you have, resizing the PNG or converting to WebP will serve you better.
  • The conversion is one-way. Once JPEG has discarded the detail, converting back to PNG restores the format but not the quality — you get a large file containing compression artefacts.
  • Any transparency-based cutout is gone for good. Keep the PNG if you might need to place the image on a different background later.

Questions

My PNG has a transparent background. What happens to it?

It becomes solid white by default, because JPEG has no alpha channel. If the image is going onto a coloured background, either keep it as PNG or convert to WebP, which supports transparency and still compresses well.

Why did my PNG barely get smaller?

It is probably a screenshot or a graphic rather than a photograph. JPEG’s compression works by discarding detail the eye does not notice in continuous-tone images; on flat colour and sharp text there is nothing for it to discard, so it saves little and introduces visible artefacts.

Which quality setting should I use?

Around 82 is the point where most photographs stop looking different from the original. 90 and above gains very little visible quality for a much larger file. Below 60 you will start to see banding in skies and blotching on skin.

What BriskFile will not do to you

  • Your files never leave your device

    Every conversion runs in your browser. Open DevTools, watch the Network tab, and you will see no upload — because there is not one.

  • No account, no email, no watermark

    Nothing to sign up for and nothing stamped on your images. There is no step between choosing a file and getting it back.

  • No limits at the download button

    No daily cap, no file counter, no "upgrade to download". If the tool starts a job, it finishes it.

  • Checkable, not just claimed

    Open the Network tab and convert something — nothing goes out. Or load the page, disconnect, and watch it keep working: the tool is already on your machine, and your file never leaves it.
