Why it matters
A real resampling filter
The filter widens as the image shrinks, so fine detail averages instead of aliasing into a moire.
Transparency survives
Alpha is handled separately from colour, so a cutout does not pick up a fringe of whatever was behind it.
Exact sizes
You get the pixel dimensions you typed, not a rounded approximation.
Questions
How do I convert Image to PNG?
Drop your Image file on this page, check the preview, and press Download. The PNG is made in a few seconds, with no sign-up.
Is my Image file uploaded anywhere?
No. The image to png conversion runs in your browser, on your own device. The file never leaves it.
Can I stretch it out of proportion?
Yes. Untick the proportion lock and set both numbers.
Does enlarging add detail?
No tool can add detail that was not photographed. Enlarging interpolates what is there and sharpens the result.
