FAQs
Are my images uploaded to a server?
No. Optimization runs entirely in your browser, so your images are never uploaded or stored anywhere.
Does optimization remove metadata?
Yes. Re-encoding the image drops EXIF data such as camera settings, GPS location and timestamps.
Which output format is smallest?
WebP usually gives the smallest files for photos and graphics, while PNG is best for images that need transparency.
Is the tool free to use?
Yes. Every Handio tool is free, with no sign-up, no limits and no watermarks.

Why use Image Optimizer?
Use this tool when an image needs to be leaner for the web and clean of hidden data at the same time — re-encoding shrinks the file while silently dropping EXIF, GPS and camera details.
- Prepare a set of blog images by trimming size and stripping GPS data before they go live.
- Modernize old JPGs into WebP so an existing site loads faster without re-shooting anything.
- Clean up marketing photos before sharing them publicly so no camera or location details leak.
Tips and Limits
The side effect of removing metadata is a re-encode, so quality is tied to the slider — keep it above roughly 70% unless the file must be as small as possible. WebP gives the largest savings for photos, while PNG is the right pick when transparency must survive. Process multiple files at once — all in your browser.
