- Set the target size in MB and the max edge in pixels
- Compress, then download images singly or as a ZIP
Frequently asked questions
How much smaller will my image get?
Depends on the target you set — a 4000px photo capped at 1920px and 1MB typically drops 50-90%; aggressive targets show visible artifacts.
Are images uploaded anywhere?
No — compression and ZIP packaging run entirely in your browser.
Does PNG transparency survive?
When output stays PNG the alpha channel is preserved; if the compressor falls back to a JPEG path, transparent areas get a white background.
