What is an image file size?
Every digital photo is a grid of tiny coloured dots called pixels. Your camera or phone decides how many dots fit in each row and column — a 4000×3000 photo holds 12 million of them, which is where the word “megapixel” comes from.
Each dot has to be stored somewhere, so more dots means more bytes. The file format matters too: JPG squeezes similar colours together to save space, while PNG keeps every dot exactly as it is — which is why the same picture can weigh 200 KB in one format and 2 MB in another.
When a site talks about “file size”, it simply means this storage weight, usually shown in kilobytes (KB) or megabytes (MB).
How can I reduce my image's file size?
There are two levers, and they do different things. Resizing changes the dot grid itself — shrinking a photo from 4000×3000 to 1900×1100 throws away roughly three quarters of the pixels, so the file gets dramatically smaller without looking any different at normal viewing sizes.
Compression keeps the grid but stores it more cleverly. With JPG you pick a quality level: 90% looks identical to the original for most photos, while 60% can halve the file size again with only tiny artefacts if you look very closely.
The practical recipe: first resize to the dimensions you actually need — about 1900×1100 is plenty for the web — then save as JPG at around 90% quality. That is exactly what this tool does in one click, and your images never leave your device while it happens.
