Resize PNG Online: what it does
PNG is a useful image format for illustrations, screenshots and graphics that need transparency. Unlike standard JPEG, PNG supports an alpha channel, which means parts of the image can remain see-through. ResizeMyImage can change the pixel dimensions of an uploaded PNG and export a new PNG file.
Keep PNG edges clean
PNG is useful for screenshots, logos, illustrations and images with transparent regions. The output is lossless at the encoder stage, but resizing still resamples existing pixels and cannot make an already blurry screenshot sharp.
This page begins with PNG as the output format. When a platform requests a tiny JPEG upload, use a KB compressor instead: strict small KB limits are not always achievable while retaining PNG transparency.
PNG for screenshots, graphics and transparency
Choose your output width and height and leave the Download format set to PNG. Use Crop to fill an exact frame or Fit with background to preserve all original edges.
Before you download: limits and trade-offs
PNG typically makes sharper-looking text and interface screenshots than a low-quality JPEG, though the output can be much larger in bytes. A transparent PNG retains alpha when cropped without adding an opaque background.
Quick answers for this image task
Can PNG be smaller than JPG?
For flat-color graphics it sometimes can; complex photographs usually compress smaller as JPEG.
Does this resize tool set a PNG size limit?
No. It resizes pixels; an exact PNG KB target is not provided by this tool.
