CBR to JPG
Get the individual page images out of a RAR-based comic archive as a ZIP of JPG files, ready for editing, printing, wallpapers or a new archive
-
Original JPEGs untouched: Pages that are already JPEG are copied byte for byte. Nothing is re-compressed, so the quality is exactly what the scanner or publisher delivered.
-
Other formats converted: PNG, WebP, GIF or BMP pages are converted to JPEG with ImageMagick at quality 92, close to visually lossless.
-
One ZIP, all pages: The result is a single ZIP with the pages in their original order and names, so you can pick the ones you need.
You can upload up to 20 ebooks simultaneously.

How the converter unpacks a CBR
A CBR is a RAR archive that has been renamed. Our server extracts it with the official unrar tool, which understands every RAR version including RAR5, converts any non-JPEG page to JPEG and zips the pages again. No comic reader or WinRAR is needed on your side.
How to use Converter App
1
Upload the CBR
One archive per conversion, from your computer or Google Drive. Password-protected and multi-part archives are not supported.
2
Extract and convert
unrar unpacks the pages. JPEGs are kept as they are; other image formats are converted to JPEG at quality 92.
3
Download the ZIP
Unpack it on your computer or phone to get the page images with their original names.
Key features
Lossless for JPEG pages
In our test the extracted 001.jpg was identical to the file inside the archive, down to the last byte.
Predictable naming
Converted pages keep their original name with .jpg appended, for example 002.png becomes 002.png.jpg, so the sort order of the comic is unchanged.
Any RAR version
unrar 6 handles RAR 2, 3, 4 and 5 archives, including solid archives created by current WinRAR.
Top-level pages only
Images inside subfolders of the archive are not included. Almost all comics keep their pages at the top level; if yours does not, our CBR to CBZ tool keeps the folder structure.

What a CBR actually contains
The CBR format was born around 2000 when the CDisplay reader started opening RAR archives full of scanned pages. The archive holds image files, almost always JPEG at 1200 to 2500 pixels wide, sometimes PNG for clean digital releases, occasionally WebP in newer releases. The pages are named so that they sort correctly, for example 001.jpg to 024.jpg, and may be accompanied by a ComicInfo.xml with series and issue metadata. RAR was chosen because it supported recovery records and solid compression; for images that are already compressed, neither matters, and the format's licensing has since made ZIP-based CBZ the standard. Extracting a CBR to JPG is therefore a lossless operation for the typical comic: the pages come out exactly as they went in.
How the extraction works on our server
The uploaded archive is unpacked with unrar, the reference decompressor from RARLAB, into a temporary folder. The script then looks at every file at the top level of the archive. Files that already end in .jpg are left alone. Every other file is handed to ImageMagick 7, which decodes it and writes a JPEG at quality 92 next to it with .jpg appended to the name. Finally all JPEG files are packed into result.zip, which is what you download. We verified the behaviour with a test archive containing a JPEG, a PNG, a WebP and a subfolder: the JPEG was byte-identical after extraction, the PNG and WebP became JPEGs of the same pixel size, and the image in the subfolder was not included.
Working with the extracted pages
- Selecting pages: open the ZIP, copy the pages you need and leave the rest; the file names keep the comic's order.
- Building a PDF: our JPG to PDF converter joins the pages into a single document at full resolution, which is the way to get a print-quality PDF rather than a screen-sized one.
- Repacking: zip the pages again, with numbered names, and rename the archive to .cbz for a universally readable comic.
- Editing: the JPEGs open in any image editor. Save edits as PNG or at JPEG quality 95 or higher to avoid generation loss.
- OCR and translation: page images can be fed into OCR tools to extract the lettering, which is handy for fan translations and accessibility.

CBR to CBZ repacks the archive losslessly, including subfolders and metadata files, when all you need is a readable format. CBR to PDF and CBZ to PDF render the pages into a screen-sized PDF for phones and tablets. CBZ to JPG does exactly what this page does for ZIP-based archives. And if you have a PDF comic instead, PDF to JPG extracts its pages as images.
FAQ
Frequently Asked Questions
Why would I turn a comic into single images?
To use a panel or page as a wallpaper or in a presentation, to crop or edit pages, to print a few pages, to run OCR on the lettering, to build a PDF from selected pages with our JPG to PDF converter, or to repack the pages into a CBZ with a different page order. A CBR is only a container; the pages inside are ordinary images once extracted.
Is the image quality reduced?
Not for JPEG pages, which are copied without decoding. Pages in PNG, WebP, GIF or BMP are converted to JPEG at quality 92, which keeps artefacts invisible at normal viewing sizes but is not lossless; a PNG page with flat colours and sharp lettering typically grows in size and gains slight ringing around the lines. If you need those pages untouched, extract the CBR with 7-Zip or WinRAR on your computer, or convert it to CBZ and unzip that.
Can I upload several CBR files at once?
Convert one archive at a time. The converter writes a single result ZIP per job, and with several archives in one upload only the last one would be returned. Multi-part RAR archives split into .part1, .part2 and so on must be joined on your computer before uploading.
My CBR will not extract. What is wrong?
The three usual causes are a password-protected archive, which cannot be opened without the password; a file that is actually a ZIP renamed to .cbr, which you can simply rename to .cbz and unzip; and a damaged download, which unrar reports as a CRC error. RAR5 archives from current WinRAR versions are supported.
Why do converted pages have names like 002.png.jpg?
The converter appends .jpg to the original file name instead of replacing the extension, so a page that was 002.png is delivered as 002.png.jpg. This keeps the alphabetical order of the pages identical to the archive. Rename the files on your computer if you prefer clean names; a bulk rename tool does it in one step.
Are my comics stored on the server?
The uploaded archive and the extracted pages are deleted automatically after two hours. They are used only to produce your download and are not inspected, indexed or shared.
