Common uses
Smaller attachments
Keep the aspect ratio and reduce the long edge to 1600px or less to shrink many photos substantially.
Transparent backgrounds
Use PNG or WebP to retain transparency. JPEG fills transparent areas with white.
What determines output quality
Pixel dimensions, format, image detail, and device limits all affect the final file.
Pixels and file size are different
Fewer pixels usually mean a smaller file, but color variation, detail, and format change how much it shrinks.
Choose a format for the content
JPEG suits photos, PNG preserves sharp graphics and transparency, and WebP often provides a smaller modern alternative.
Browser limits apply
Input is capped at 20 MiB and each output side at 8192px. Large images may take longer on memory-limited mobile devices.
