PDF to CR2 Converter

About PDF

PDF (Portable Document Format) was created by Adobe in 1993 and standardised as ISO 32000 in 2008. It is the universal container for documents that must look identical on every device — fonts, layouts, vector graphics, embedded images, and hyperlinks all render consistently regardless of the operating system, application, or screen resolution.

When converting a PDF page to an image format (JPG, PNG, WEBP, or AVIF), the PDF is rasterised: each page is rendered as a grid of pixels at a specified DPI (dots per inch) resolution. This site uses ImageMagick with a Ghostscript backend for PDF rasterisation. At 150 DPI, an A4 page renders to approximately 1240 × 1754 pixels — sufficient for most presentation, social media, and documentation use cases. For print-quality output, higher DPI values produce proportionally larger pixel dimensions.

Transparency in PDFs is handled differently depending on the output format. JPEG has no alpha channel, so transparent areas are composited against a white background before encoding. PNG and WEBP retain the alpha channel, so transparent page regions produce transparent pixels in the output. Only the first page is extracted per conversion — for multi-page extraction, split the PDF first.

About CR2

CR2 (Canon Raw version 2) is the proprietary RAW file format used by Canon EOS DSLR cameras from approximately 2004 through 2018 — models including the 5D, 5D Mark II, 5D Mark III, 7D, 7D Mark II, 70D, 80D, and the Rebel series (1100D through 800D). Like all RAW formats, CR2 stores the unprocessed sensor data captured at the moment of shooting: 14-bit color depth per channel, full dynamic range before any white balance or tone curve is applied. Photographers shoot in CR2 precisely for this latitude — a file that appears underexposed or color-shifted can be recovered in post-processing without visible quality loss that would occur if the correction were applied to an in-camera JPG.

The tradeoff is compatibility. CR2 files require Canon's Digital Photo Professional, Adobe Lightroom, Adobe Camera Raw, or another RAW-capable editor to open. They are not displayable in browsers, email clients, social platforms, or most general-purpose applications. Converting to JPG produces a universally compatible file that opens in every application without additional software or codec downloads.

When CR2 to JPG makes sense

Any delivery or sharing scenario that prioritises compatibility over editability calls for JPG. Sending shots to a client by email, uploading to a social platform, publishing to a photography blog, or submitting to a print lab that accepts JPEG — all require a processed output. This converter provides a direct path from CR2 sensor data to a ready-to-share JPG or PNG without opening a desktop application.

About this conversion

Conversion uses ufraw-batch to decode the CR2 sensor data, then Imagick to produce the output JPG, PNG, or WebP. The decode applies default auto white balance and a linear tone curve — a neutral, flat render without Canon's Picture Style profiles (Standard, Portrait, Landscape, etc.) or in-camera sharpening. The output is technically correct but intentionally neutral. It is a starting point, not a finished edit. For output that replicates the camera's own JPEG output style exactly, export from Canon Digital Photo Professional or Adobe Lightroom with your chosen Picture Style applied.

File size note

CR2 files from Canon DSLRs range from 10–30 MB depending on camera model and megapixel count. This converter has a 20 MB upload limit. Files from high-resolution bodies — particularly the 5DS (50 MP) and 5DS R (50 MP) — frequently exceed 30 MB uncompressed. In that case, reduce resolution in-camera, enable in-camera RAW compression if available, or export a high-quality JPEG from your RAW editor and use this converter for format-only conversion.
