How to convert a PNG to JPG
Quick answer
Upload your PNG, choose the output quality, and download it as a JPG. Transparency is not supported in JPG, so any transparent area is filled with a solid background first.
- 1Upload your PNG.
- 2Choose the quality.
- 3Convert.
- 4Download the JPG.
Free, no sign-up, and your file is read on your own device rather than uploaded.
PNG and JPG solve different problems: PNG stores an image losslessly and supports transparency, which makes files larger; JPG compresses the image, trading a little quality for a much smaller file, and has no transparency at all. Converting to JPG is the right move when the file needs to be smaller and the image does not rely on a transparent background.
A screenshot, a diagram exported as PNG, or a photo saved as PNG by mistake all typically shrink considerably once converted to JPG at a reasonable quality.
Step by step
Choose the quality
Higher quality keeps more detail at a larger file size; lower quality shrinks the file further with more visible compression.

Tips
- If the PNG has a transparent background, converting to JPG fills that area with a solid colour, since JPG cannot represent transparency at all - check the result if your original relied on a transparent background.
- A PNG of a photograph converts to JPG with a large size reduction and very little visible quality loss; a PNG of text or line art can look softer, since JPG compression is tuned for photographic detail.
- Going the other way? Use JPG to PNG instead if you need lossless quality or transparency rather than a smaller file.
Common problems
The converted JPG has a solid colour where the PNG was transparent.
That is expected - JPG does not support transparency, so any transparent area is filled with a background colour during conversion. If you need to keep transparency, JPG is not the right format; stay with PNG or use WebP instead.
The JPG doesn't look as sharp as the original PNG.
PNG is lossless and JPG compresses the image - some quality difference is expected. Increase the quality setting if sharpness matters more than file size for this particular image.
Frequently asked questions
- Does converting PNG to JPG reduce file size?
- Usually significantly, especially for photographs - PNG's lossless storage makes it much larger than a JPG at a comparable visual quality.
- What happens to transparency when converting to JPG?
- It is filled with a solid background colour, since JPG has no way to represent a transparent pixel.
- Can I control the JPG quality?
- Yes - a quality setting controls the balance between file size and visual detail in the output.
- Is my image uploaded to a server?
- No. Conversion happens entirely in your browser, on your own device.

JPG or PNG? How to choose, and convert between them
JPG compresses the image for a smaller file, at a small cost to quality, and has no transparency - use it for photographs. PNG stores the image losslessly and supports transparency, at a larger file size - use it for screenshots, diagrams, logos and anything with sharp lines, text or a transparent background.

Need a smaller image for email? Compress it in your browser
Upload your image, choose a quality level or a target file size in KB, and download the smaller result. A photo usually shrinks the most; a screenshot or graphic responds less.
