Images · file size
Why is my image still too big after I resized it?
Because dimensions and file size are related, but they are not the same thing. Sometimes resizing is only the first step.
In plain English
An image can have smaller dimensions and still carry a lot of data. File format, compression and image detail all affect the final size. If the image is for the web, a useful sequence is to resize it for the space it needs to fill, compress it, then convert it to a suitable format if that helps.
- Resize first so you are not compressing pixels you do not need.
- Compress next to reduce the file weight without changing the dimensions again.
- Convert only when another format makes sense for where the image is going.
