About the image compressor
How this tool works
Image compression is more useful when it shows the size change clearly instead of just handing back a new file. This page focuses on that before-and-after workflow.
It lets you control format, quality, and optional width reduction in the same shared interface, which covers most everyday compression tasks.
Where it is useful
Because everything happens in the browser, it is a good fit for private images and quick one-off upload prep.
The registry-first architecture also means future file tools can reuse the same result and validation model instead of inventing new page logic.

FAQ
3 answersHow does the quality setting affect compression?
Lower quality settings usually reduce file size more, but they can introduce visible artifacts in lossy formats like JPG and WEBP.
Should I also shrink the width when compressing?
Often yes. Lowering quality helps, and capping the width can reduce large images even further.
When should I use an image compressor?
It is useful for uploads, email attachments, CMS media libraries, and any workflow where image size matters.
