ZIP to PDF — Free ZIP File to PDF Converter (Images & CBZ)

ZIP to PDF — Free ZIP File to PDF Converter (Images & CBZ). Convert a ZIP or CBZ file of images to one PDF for free. Pages are sorted naturally, can be reordered or removed, and fit to image, A4 or Letter — all in your browser, no upload.

Still JPG, PNG, GIF, BMP and WebP images only. Animated or unreadable images are skipped with a notice; other documents are not converted. ZIP/CBZ up to 20 MiB, 500 entries and 100 images. Each image: 20 MiB, 24 megapixels and 8,192 pixels per edge.

Expanded/prepared images and the PDF: 50 MiB. A 60-second timeout applies to each step. Use standard, unencrypted UTF-8/CP437 archives. Validated PNGs and JPEGs without EXIF rotation or mirroring go directly to the PDF engine without canvas re-encoding.

Oriented JPEGs and static GIF, BMP and WebP images are normalized to PNG using the browser’s displayed orientation. The PDF contains images, without OCR. Check every page, orientation and colors before sharing; embedded JPEGs may retain original metadata.

Files are processed on this device and are not uploaded or saved in browser storage by this tool. Advertising makes separate network requests. Changing pages or layout removes the old download; Cancel or choosing another archive stops the current job.

Frequently asked questions

How do I convert a ZIP file of images to PDF?

Drop a .zip or .cbz file onto the upload area or click to browse. The images inside are extracted and listed as pages; adjust the order and PDF options, set the PDF file name, click Build PDF and then Download PDF.

Which files inside the ZIP are supported?

Still JPG, PNG, GIF, BMP and WebP images only. Animated or unreadable images are skipped with a notice; other documents are not converted. ZIP/CBZ up to 20 MiB, 500 entries and 100 images. Each image: 20 MiB, 24 megapixels and 8,192 pixels per edge. Expanded/prepared images and the PDF: 50 MiB. A 60-second timeout applies to each step. Use standard, unencrypted UTF-8/CP437 archives.

How are the PDF pages ordered?

By default pages are sorted by file name in natural order, so page2 comes before page10. Page order can also be set to Z to A or to the order inside the archive, and you can move single pages with the up and down arrows or remove them with the cross button.

Which page size should I choose?

Fit page to image makes each page exactly the size of its image, which suits comics and scans. A4 or US Letter scales each image to fit the page and turns the page to landscape for wide images. Add a Small (0.25 in) or Large (0.5 in) margin if you plan to print.

Can I convert CBZ comic files to PDF?

Yes. A CBZ file is a ZIP archive of comic pages, so it works exactly the same way: drop it in, check the natural page order and build the PDF.

Is my ZIP file uploaded to a server?
