What linearization does
A normal PDF keeps its index at the end of the file, so a browser must download everything before showing anything. A linearized PDF puts what the first page needs at the start.
Adobe calls this "Fast Web View". It matters most for large PDFs on slow connections, such as phone users opening a 20 MB catalogue.
Tip: Compress the PDF first, then optimize it for the web, for the fastest result.
Your files stay on your device
Most online PDF sites upload your documents to their servers. Aleynray Ai does the work inside your browser instead, on your own computer or phone.
Nothing is sent anywhere, so contracts, bank statements, IDs and medical forms stay private, and there is no waiting for uploads.

Frequently asked questions
Does linearizing change the PDF?
Only the order of data inside the file. What you see is identical.
Will it make the file smaller?
Not by itself. Use Compress PDF for that, then optimize.
Do I need it for email attachments?
No. It only helps when PDFs are opened over the web.
Is it free?
Yes. There is no sign-up, no limit on files and no watermark.
Are my files uploaded?
No. The tool runs inside your web browser and works on the file on your own device. Nothing is sent to a server, so private documents stay private.
