Convert PNG to JPG
PNG screenshots and exports are often several times larger than they need to be. Convert them to JPG here, in your browser, with nothing uploaded.
Or click to choose them. Pasting from the clipboard works too, and so does a whole batch at once.
Nothing here is uploaded. See how the page enforces it.
What changes when you convert
PNG stores every pixel exactly. That is ideal for screenshots and logos, and wasteful for photographs: a photo saved as PNG is routinely five to ten times bigger than the same photo as a JPG that looks identical.
Two things change in the conversion, and both are worth knowing before you run it:
- Transparency disappears. JPEG has no alpha channel at all. Anything transparent is filled with white. Not made invisible: filled. If your PNG has a transparent background and it needs to stay transparent, convert to WebP instead.
- The encoding becomes lossy. At quality 88 the difference is invisible on a photograph. On a screenshot full of small text it is not: JPEG puts a faint halo around sharp edges. Keep screenshots as PNG.
When PNG to JPG is the right call
| Your PNG contains | Convert to JPG? |
|---|---|
| A photograph | Yes, a large saving with no visible change |
| A screenshot with text | No. Keep PNG; the text will blur |
| A logo with a transparent background | No. You would lose the transparency |
| A scan of a document | Only at quality 90+, otherwise the text suffers |
| A photo exported from design software | Yes |
Questions
Does converting PNG to JPG reduce quality?
JPEG is a lossy format, so some information is discarded. At the default quality of 88 that loss is invisible on photographs at normal viewing size. On text and sharp edges it is visible, which is why screenshots should stay PNG.
What happens to a transparent background?
It becomes white. JPEG cannot store transparency. If you need to keep it, convert to WebP, which supports both transparency and small files.
How much smaller will the file be?
For photographs, typically 70–90% smaller. For flat graphics, sometimes larger than the PNG, because JPEG is poor at large areas of a single colour.
Can I convert many PNGs at once?
Yes, as many as your device can hold, and download them together as a ZIP. There is no cap and no paid tier.
Are my files uploaded?
No. The conversion runs in your browser using the standard Canvas API. Nothing is sent to a server, so there is nothing to delete afterwards.
