How Do You Convert CBR to PDF?
You convert CBR to PDF by adding the comic to QuickCatPDF's CBR to PDF converter and clicking Convert to PDF. Each picture in the archive becomes one PDF page, in the right reading order, with the pictures kept at their original quality.
CBZ and CB7 comics convert the same way. It's free, with no sign-up and no watermark.
How to Convert a Comic to PDF With QuickCatPDF
Turning a comic archive into a PDF takes four steps.
- Click Select comic files or drop your CBR or CBZ files on the page (up to 10 files).
- Keep Page size on Each picture's own size, or choose A4 or Letter.
- For several issues, choose Separate PDFs or One combined PDF.
- Click Convert to PDF, then download each PDF, the ZIP or the combined PDF.
Why Use QuickCatPDF for Comics?
QuickCatPDF places JPEG and PNG pages in the PDF without re-compressing them, so the artwork looks exactly as it did in the archive. Pictures in other formats, such as WebP, are converted once to a lossless format.
Pages are sorted the way people number them, so page 2 comes before page 10 even when the files aren't numbered with leading zeros. In our test, a CBR with pages named 1, 2 and 10 converted in about a second into a 3-page PDF in that order, and the JPEG pages in the PDF were byte-for-byte identical to the pictures in the archive.
Comics are sent over HTTPS, unpacked and converted in a sandboxed service with no internet access, and deleted right after conversion.
What's the Difference Between CBR and CBZ?
Both are ordinary archives full of page pictures, renamed so comic readers recognise them.
| Format | Archive type | Converts here |
|---|---|---|
| CBZ | ZIP | Yes |
| CBR | RAR | Yes |
| CB7 | 7-Zip | Yes |
The archive type doesn't affect the PDF; the pictures inside are what matter. Archives protected with a password can't be opened.
Which Page Size Should You Choose?
Keep Each picture's own size for reading on screens: every page is exactly the shape of its picture, so nothing is cropped and there are no white borders. Choose A4 or Letter when you want to print, and each picture is fitted onto the paper with its proportions kept.
A comic page 800 pixels wide becomes a page about 5.3 inches wide at the default size, matching 150 pixels per inch, which reads at a comfortable size in any PDF viewer.
Frequently asked questions
Is CBR to PDF free?
Yes, free with no sign-up and no watermark, with a fair-use limit of 60 files an hour.
Does converting reduce the picture quality?
No, JPEG and PNG pictures go into the PDF unchanged. Other picture formats are converted without loss.
Can I join several issues into one PDF?
Yes, add the issues, put them in order with the arrows, and choose One combined PDF. Each issue gets its own bookmark.
What's the size limit?
Each comic can be up to 100 MB, and you can convert up to 10 at once. To join PDFs you already have, use Merge PDF.
My pages come out in the wrong order. Why?
Pages are sorted by file name, including folders inside the archive. If the files have names like "page-a" and "page-b" rather than numbers, the order follows those names.
Can I convert a folder of pictures instead of an archive?
Yes, for loose pictures use JPG to PDF, which builds one PDF from many images. Scanned books in DjVu format convert on DjVu to PDF.
