CBZ is just a ZIP of pictures
A CBZ file is a ZIP archive full of page images. Comic apps understand it, but many e-readers and phones don't. A PDF opens everywhere and keeps the pages in order.
CBR files are RAR archives, which this tool can't open yet. Most comic apps can save a CBR as CBZ.
Tip: Going the other way? PDF to CBZ turns a PDF comic into a CBZ.
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.

- Works on desktop and mobile
Frequently asked questions
Does it support CBR files?
Not yet. CBR uses the RAR format; convert it to CBZ in your comic app first.
Will the pages lose quality?
No. JPEG pages are copied into the PDF exactly as they are.
Can I open a plain ZIP of images?
Yes. Any ZIP that contains images works the same way.
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.
