Convert PNG to JPG

Choose a PNG and this page writes a JPG from it inside your browser; the file is not sent anywhere. You control the JPEG quality and the solid color that replaces transparency. The caveat that matters most: JPEG has no alpha channel, so every transparent or semi-transparent pixel is blended permanently onto that background color.

Tool facts

Transparency
Flattened onto the Transparency background color, white (#ffffff) unless you change it
Quality range
50–95% in steps of 5, with 85% preselected
PNG input limit
12 MiB, 8,192 px per side, 24 MP in total
Batch
12 files and 96 MiB per run with shared settings, saved as one ZIP
Color profile
An embedded ICC profile is not copied; the JPG is encoded from an sRGB canvas

How to convert PNG files to JPG

  1. 01

    Add the PNG

    Press Choose file or drag PNG files into the drop zone. Selecting several files queues them, and each one is checked when its turn comes.

  2. 02

    Pick the background

    Use the Transparency background color picker to choose what fills transparent areas. Match it to the page or slide the image will sit on.

  3. 03

    Set Quality

    Leave the slider at 85% or move it: lower values give smaller files with more visible compression, higher values keep more detail.

  4. 04

    Convert and compare

    Press Convert image, read the Size change figure, and download the JPG once the trade-off looks right.

What happens when a PNG becomes a JPG

PNG is lossless and supports transparency, which makes it the usual export for screenshots, interface mockups and logos. JPEG gives up both: it compresses lossily and stores only opaque color. The switch pays off when a destination demands JPG or caps the upload size and the picture is photographic.

How much smaller the file gets depends on the content, so the converter measures it instead of promising a number: the Size change readout compares the real bytes. Flat-color graphics and crisp text can come out barely smaller, or even larger, and lossy compression can soften the edges of letters.

Flattening cannot be undone in the JPG. A logo converted on white keeps that white rectangle wherever it is placed, so pick the background that matches its destination, or keep the PNG when transparency has to survive.

Common questions

Why does my logo have a white box after converting?
JPEG cannot store transparency, so the converter paints the Transparency background color behind the image before encoding. White is the default; choose the color of the surface the logo will sit on and convert again.
Which JPG quality setting should I use?
Start from the default 85% and judge the result by eye and by the Size change readout. Drop toward 50% for tight upload limits; move toward 95% when fine texture matters more than bytes.
Why did my screenshot barely get smaller?
Flat color and sharp edges leave lossy compression little to remove, so the JPG may save little or nothing and soften text. Compare the Size change readout and keep the PNG when the JPG is not smaller.
Can I convert many PNG files at once?
Yes. Choose up to 12 PNG files totalling no more than 96 MiB; the same quality and background apply to each, and the results arrive as a single ZIP.
Does the JPG keep the PNG's color profile?
No. Pixels are drawn onto an sRGB canvas and the source ICC profile is not carried over, although the browser may tag the output with its own. Compare colors against the original before using the JPG for print or brand work.
