Frequently asked questions
- How can I compress a PDF to less than 100KB?
- Choose the Strong or Flatten to images level. If the document has high-resolution scanned pictures, Flatten to images achieves the highest possible compression to reach under 100 KB.
- Are my certificates and personal files uploaded to a server?
- No. All compression runs locally on your device in the browser. Zero bytes are uploaded to our server or any third party.
- Will my text remain readable at 100KB?
- Yes. The algorithm preserves text sharpness and optimizes internal image resolution so numbers, names, and text remain crisp and legible.
