- Free, no sign-up
- No watermark, no file limit
About this tool
PNG screenshots and exports are often far larger than they need to be, and many Indian portals accept only JPG. Converting fixes both — usually cutting the file to a fraction of its size. The one thing to decide first is what should happen to any transparent areas, because JPG cannot store them.
Your images never leave your device. Each file is decoded by your browser, drawn to a canvas and re-encoded in the new format in memory. Nothing is uploaded, which matters when the image is an ID document, a signature or a private photograph.
How to use this tool
- Add your PNG images.
- Choose what transparent areas should become — white suits nearly every use.
- Set the quality. 85–90% is the sweet spot for photographs.
- Press Convert to JPG and check the size reduction.
What the PNG to JPG does
PNG keeps every pixel exactly, which is why a full-screen screenshot can run to several megabytes. JPG compresses by discarding detail the eye is poor at noticing, and for photographs the difference is invisible at 85–90% quality while the file is a tenth of the size.
Transparency is the catch. JPG has no concept of it, so any transparent area must become a solid colour. White is right for almost every form and document; the option is there because occasionally it is not.
Transparency and quality
TRANSPARENCY
The chosen background is painted first, then the image
is drawn on top. Transparent pixels show the background;
semi-transparent pixels blend into it.
QUALITY (JPG only)
100% visually lossless, largest file
90% no visible difference in normal viewing
85% recommended — big saving, no visible loss
70% slight softening in fine detail
50% visible blocking around edges and text
Screenshots with text suffer more at low quality
than photographs do — sharp edges are what JPG handles worst.
Worked example
Example: a screenshot
| Input | 1920 × 1080 PNG, 2.4 MB |
| Quality | 90% |
| Output | 1920 × 1080 JPG, about 280 KB |
| Reduction | roughly 88% |
Comfortably inside the 500 KB or 1 MB limit most portals impose, from a file that was well over it.
What your result means
A large reduction is normal for screenshots and photographs.
Transparency is gone permanently in the JPG. Keep the PNG if you may need it again.
If text looks fuzzy, raise the quality to 95% or keep the PNG — screenshots of text are the one case where PNG is genuinely better.
Things to watch out for
- Keep the original PNG if the image has transparency you might need later. The conversion cannot be undone.
- For screenshots that are mostly text, PNG often looks better and can even be smaller. Convert only if JPG is required.
- White is the safe background choice for forms, applications and printing.
- To hit a specific KB limit rather than a quality percentage, use the KB optimiser.
- JPG re-saves lose a little each time, so edit the PNG and convert once at the end.
Limitations of this tool
- Transparency cannot be preserved — JPG does not support it.
- Images are capped at 8000 px on the longest side.
- Animated PNGs produce a single frame.
- Metadata is not carried across.
Frequently asked questions
What happens to transparent areas?
They become the background colour you choose, white by default. JPG cannot store transparency, so there is no way to keep it — pick the colour that suits where the image is going.
How much smaller will the file be?
For screenshots and photographs, usually 80–90% smaller at 90% quality. The result reports the actual figure for your files.
What quality should I choose?
85–90% for almost everything. Go to 95% for screenshots containing small text; below 70% the loss becomes visible.
Can I convert back to PNG later?
You can, but it will not restore what JPG discarded. Keep the original PNG if you might need it.
