Why compress images?
Smaller images upload faster and can improve web delivery. Compression trades some visual information for fewer bytes.

Privacy and file handling
This tool is designed for browser-side processing. SwiftFileTool does not intentionally upload the selected image to a conversion server. Third-party resources loaded by the page can still make ordinary network requests; see our Privacy Policy.
What to expect
For large photos, resizing can reduce file size more dramatically than compression alone.
