What this does
Each picture keeps its format and is compressed again, either at the quality you set or to fit under a size you type in.
What it can’t do
Undo compression. Keep the original if you may need the full quality later.
A worked example
A visa form allows photos up to 240 KB. With the target set to 240 KB, a 3.1 MB phone photo comes out at 236 KB with its full dimensions.
Questions
- How small can it get?
- A phone photo usually drops to a fifth of its size with no visible change. Type a target size and the tool gets as close as it can.
- Why didn't my PNG shrink?
- PNG stores every pixel exactly, so there is little to save. Convert it to JPG or WebP for a large reduction.
- Will the picture change size in pixels?
- Only if the target size cannot be reached any other way. The tool tells you when it had to.
Your file stays on this device
The tool above runs in a sealed frame that cannot send your file anywhere. It works with airplane mode on, and the counter above it stays at 0. Here is how you can check that yourself.
