  3. Choose the resolution. If unsure, use "Standard".

Notes

  • Pages are turned into images and made monochrome, so text can no longer be selected or searched.
  • Grayscale suits photos and figures. Pure black & white suits text-only documents.
  • The file can get larger. If so, lower the resolution or use Compress PDF.
  • Password-protected PDFs are not supported.

FAQ

Is my PDF uploaded anywhere?

No. Everything is processed inside the browser on your device.

Is my original PDF changed?

No. A monochrome PDF is saved separately.

Light text disappears in black & white.

Pale text can turn white. In that case, use Grayscale.
