How it works
Grayscale PDF in three steps.
Choose the PDF
Select the file and the preview switches to grey so you can see the result.
Pick the quality
Standard is smaller; High quality keeps more detail for printing.
Save the grayscale PDF
Every page is redrawn in grey tones and saved as a new file.
What you can do

- Converts every page in one go

Private by design
Your PDF never leaves your device.
Grayscale PDF runs inside your browser tab. The file you choose is read from your device, processed there, and the result is saved back to your device — it is never uploaded to a Pyrbit server, so there is no copy to keep or delete.
Processed in your browser
The Pyrbit PDF engine runs on your computer or phone, not in the cloud.
No upload
Your document isn’t sent anywhere — not to us, and not to a third-party converter.
Sign-in is for your plan only
Your Google account keeps track of your free daily document and Pyrbit Pro. It never gives us your files.
Prefer offline?
The Pyrbit PDF apps do the same work on your phone, tablet or Mac — even without a connection.

FAQ
Grayscale PDF questions.
Will text still be selectable?
No. Pages are redrawn as grey images, so text in the result can’t be selected or searched. Keep the original if you need that.
Does grayscale make the file smaller?
Often, but not always — it depends on what’s in the PDF. Use Compress PDF if size is what matters.
Can I convert only some pages?
The tool converts the whole document. To convert a few pages, extract them first, convert, and merge them back.
Is Grayscale PDF free?
On the web, sign in with a Google account and you can use Grayscale PDF — or any other tool — on one free document every 24 hours. Pyrbit Pro (₹79/month or ₹599/year) gives unlimited use with no ads. The Pyrbit PDF apps for iPhone, iPad and Android are free, supported by ads.
