What it does to your PDF

Stays on your device: The compressor runs inside this browser tab. Your file is never uploaded, so there is nothing to delete afterwards and nothing to leak.
Text and screenshots stay sharp: Images of text, charts and line art keep every pixel. Photos are shrunk only as far as they still look the same, checked image by image.
Your PDF still works: Form fields, links, bookmarks and accessibility tags are kept. Signed and password-protected files are left untouched rather than broken.
