- Select Convert to JPG and download.
How it works
PNG stores every pixel exactly and supports transparency, which makes it ideal for logos, screenshots and graphics but very large for photographs. JPG discards detail the eye barely notices and is typically 5–10 times smaller for photos, which is why websites, e-mail and upload forms often ask for it.
JPG has no transparency. Transparent and semi-transparent pixels must be blended onto a solid colour; this converter lets you choose that colour instead of silently using black, the unpleasant surprise many converters produce. White suits documents and most web pages; match your page background if the image will sit on a coloured one.
JPG is the wrong choice for screenshots with small text, line art and logos: its compression creates smudges around sharp edges. For those, keep PNG and shrink it with Compress image using the "PNG, smaller" option. The conversion is done by your browser on your own device. Your photos are not uploaded, so there is no queue, no file-count limit and no copy kept anywhere.
Example
A 4.8 MB PNG photo exported from a design tool becomes a JPG of about 600 KB at 90% quality, with no visible difference.
Frequently asked questions
What happens to the transparent background?
It is filled with the colour you choose, white by default, because JPG cannot store transparency.
Does converting PNG to JPG reduce quality?
Slightly, since JPG is lossy. At 90% the change is not visible on photos. Text and sharp graphics show artefacts sooner; raise quality to 95–100% or keep those as PNG.
Why is my JPG larger than the PNG?
For simple graphics with few colours, PNG can be smaller than JPG. Convert photos and complex images to JPG; keep flat graphics as PNG.
Can I convert several PNG files at once?
Yes, any number, with a ZIP download of all results.
Limitations
- Transparency is replaced by a solid colour.
- Animated PNG (APNG) files give a single still frame.
- Metadata is not carried over.
