How to convert PNG to JPG
- Drop your .png files onto the box above.
- The output is already set to JPG.
- Choose a quality level — 90% is right for almost any photograph.
- Download the converted images individually or as a ZIP.
When this conversion makes sense
PNG is the wrong format for photographs, and a lot of photographs end up as PNG by accident — saved from a screenshot tool, exported by an application that defaults to it, or downloaded from a service that converted them. Those files are routinely five to ten times larger than they need to be.
Converting to JPG fixes that in one step, and JPEG is readable by absolutely everything.
If the destination is a website rather than a general-purpose file, consider WebP instead: it is smaller again than JPEG at the same quality.
What to watch out for
Transparency is lost. JPEG has no alpha channel, so transparent areas are filled with white during conversion. If your PNG is a logo on a transparent background, converting it to JPG will give it a white box — convert to WebP instead, which keeps transparency and is smaller too.
Sharp text and hard edges suffer more than photographs do under JPEG compression. A screenshot full of text will show visible artefacts where a photograph would not. Keep screenshots as PNG, or use a high quality setting.
Common questions
- What happens to a transparent background?
- It becomes white, because JPEG cannot store transparency. If you need it preserved, convert to WebP instead — it keeps the alpha channel and produces a smaller file than either PNG or JPG.
- How much smaller will the file be?
- For a photograph mistakenly saved as PNG, often eighty percent smaller or more. For a flat graphic or a screenshot the saving is smaller, and JPEG may not be the right format for those at all.
- Is JPG a good choice for screenshots?
- Not really. JPEG compression blurs the sharp edges of text and interface elements, and the artefacts are easy to spot. Keep screenshots as PNG, or convert them to WebP, which handles both photographs and sharp edges well.
- Are my files sent to a server?
- No. Everything happens in your browser and nothing is uploaded.
