Convert PNG to JPG
Screenshots and photographs take up needless space as PNG. Convert them to JPG and the file usually drops to a fifth of its size.
How to use it
Drop the PNG in
Drag it over or click to choose. There is no size limit — the only limit is your device's own memory.
Decide on quality
85 is the default: the point where the saving is large and the difference is invisible. If the file is still big, go lower — and stop as soon as the edges start to break up.
See the saving, download
The line underneath tells you how much smaller it got. On photographs, 70–90% is ordinary.
Why PNG files are so large
PNG throws nothing away
It is a lossless format: every pixel is kept as it is. On anything with hard edges — logos, drawings, screenshots — that gives a perfect result.
On a photograph that is a loss
A photograph holds millions of tones and your eye cannot tell most of them apart. PNG insists on keeping all of them, so the file balloons; JPG drops what the eye does not see and holds the same picture in far less space.
Screenshots sit in between
If there is text in it, PNG stays more readable; if it is mostly photographic, JPG is much smaller. This tool shows you both, so you can decide by eye.
When not to convert
You need a transparent background
JPG carries no transparency; transparent areas turn white. Keep logos, icons and cut-out images as PNG.
It is mostly text and hard lines
JPG leaves a faint blur around sharp edges. Code screenshots, charts, diagrams and tables should stay PNG.
It is a photograph
Landscapes, portraits, products, food — on all of them JPG is far smaller and indistinguishable by eye.
Common questions
My transparent PNG came out with a black background
Not in this tool — transparent areas are deliberately filled with white. Tools that give you black are encoding without setting a background colour. If you need to keep transparency, use PNG or WebP rather than JPG.
Can the quality loss be undone?
No. The detail dropped on the way to JPG is gone for good; turning that file back into a PNG does not bring it back, it only makes the file bigger. Keep the original PNG somewhere.
Does the resolution drop?
No. This tool does not touch the pixel dimensions. If you want to change those too, use Resize Image.
I have to get under a specific file size
Compress Image takes a target size and works out the quality itself — no trial and error with a slider.
