The three levers of file size
File size depends on three things: dimensions (pixels), format, and compression level. Pulling all three gives the biggest reduction with the least visible loss.
Start by resizing to the size you actually display, then convert to WebP or JPG, then compress to quality 75-85.
Match the format to the content
Photos compress best as JPG or WebP. Graphics, screenshots, and text-heavy images stay sharp as PNG or lossless WebP.
Watch the live size readout as you adjust quality — stop at the highest quality that meets your target size.
