A CR2 is Canon's raw sensor capture — most viewers, email clients, and gallery hosts can't open it. This converter demosaics the raw data, renders it to a standard image, and embeds it in a PDF anyone can view, print, or sign. Drop in several CR2 files and they become one multi-page PDF — handy for proof sheets, client review, or archiving a viewable copy next to your originals.
How to Convert CR2 to PDF
- Upload Your CR2 Files: Drag and drop your
.cr2files or click "Add Files". Add several to build a multi-page PDF in one pass. - Choose Single PDF or Individual PDFs: "Single PDF" merges every photo into one document (each image on its own page); "Individual PDFs" gives you a separate PDF per file.
- Set Paper Size and Quality: Pick a paper size (A4 by default, or Original to match the photo's dimensions) and drag the Quality Percentage slider to trade file size against detail.
- Convert and Download: Click Convert. No sign-up, no watermark — files are deleted from our servers after a few hours.
CR2 vs PDF: What Changes in the Conversion
| Property | CR2 (Canon RAW) | PDF (output) |
|---|---|---|
| Type | Raw sensor data, TIFF-based container | Page-layout document (ISO 32000) |
| Bit depth | Up to 14-bit per channel | 8-bit image embedded per page |
| Editing latitude | Full — recover highlights/shadows, set white balance | Baked in — exposure and color are final |
| Opens without special software | No (needs Canon DPP, Lightroom, etc.) | Yes (any PDF viewer or browser) |
| Multiple frames | One file per shot | Combine into a single multi-page PDF |
| Best for | Editing your negative | Sharing, printing, proofing, archiving |
Frequently Asked Questions
Will I lose image quality converting CR2 to PDF?
You lose editing latitude, not visible sharpness. A CR2 stores up to 14-bit raw sensor data so you can push exposure, white balance, and shadows after the fact. Once it's demosaiced and embedded in a PDF, the photo looks correct but the exposure and color are baked in. Keep the original CR2 if you may want to re-edit, and treat the PDF as the shareable proof.
How do I turn several CR2 files into one multi-page PDF?
Upload all of them and leave the merge option on "Single PDF" — each photo lands on its own page in the order you added them, which is the standard layout for a contact or proof sheet. Choose "Individual PDFs" instead if you need one separate file per shot.
Should I convert CR2 straight to PDF, or to JPG first?
Go straight to PDF when the end goal is a viewable, printable document or a multi-image proof sheet. If you instead want an editable, re-shareable photo you can drop into other apps, convert to a standard image with our CR2 to JPG converter — JPG stays an image you can crop or re-export, whereas the PDF is a finished page.
My CR2 won't open in my editor — will this still convert it?
Probably. CR2 (Canon Raw version 2) shipped on Canon DSLRs from the EOS 350D/20D era until 2018, when newer models switched to CR3. Older software that predates your camera often can't read its specific CR2 variant. Our converter reads the raw payload server-side, so you don't need Canon's Digital Photo Professional installed to get a usable PDF.
The output PDF is too large to email — how do I shrink it?
Lower the Quality Percentage slider before converting; a 24-megapixel frame at 70-80% is usually plenty for screen review and cuts the file substantially. If you've already exported a large multi-page PDF, run it through our PDF compressor to bring it under typical email caps — Gmail, for example, attaches files up to 25 MB.
Are my photos kept private during conversion?
Yes. Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours. In our testing, a single 24-megapixel CR2 at default quality produces a one-page PDF around 1-2 MB. There's no sign-up, no watermark, and your files are never shared or made public.
