CR2 vs JPG
Um comparativo detalhado de Canon RAW CR2 e JPEG Image — tamanho de arquivo, qualidade, compatibilidade e qual escolher de acordo com seu fluxo de trabalho.
Comparar CR2 e JPG não é só sobre tamanho — profundidade de cor, transparência e compatibilidade importam. Aqui vai a análise prática.
Canon RAW CR2
Raster & Vector ImagesCR2 is Canon camera RAW format containing unprocessed sensor data.
Sobre os arquivos CR2JPEG Image
Raster & Vector ImagesJPEG is the most widely used lossy image format on the web. It achieves small file sizes through adjustable compression, making it ideal for photographs and complex images where some quality loss is acceptable.
Sobre os arquivos JPGComparativo de vantagens
CR2 Vantagens
- Mature — 13 years of camera bodies and tooling.
- Preserves every bit of Canon sensor data for post-processing.
- Embedded JPEG preview makes browsing fast.
- Supported by every major raw processor.
JPG Vantagens
- Excellent compression ratio for photographs (10:1 or better without visible quality loss).
- Universal support — every camera, phone, OS, and browser reads JPEG natively.
- Adjustable quality setting balances file size against visual fidelity.
- Embeds EXIF metadata (camera model, GPS, exposure) automatically.
- Progressive rendering for graceful loading over slow networks.
Limitações
CR2 Limitações
- Proprietary — no official spec, tool support depends on reverse engineering.
- Canon-only tags (Picture Styles, DPP adjustments) are lost when processed outside DPP.
- Superseded by CR3 in 2018 — format is frozen.
- File sizes are large (20-40 MB typical).
JPG Limitações
- Lossy — every save degrades the image further (generation loss).
- No transparency channel (use PNG or WebP for that).
- Visible compression artifacts on text, sharp edges, and flat colors.
- Limited to 8 bits per channel — poor for HDR or print work.
- Baseline JPEG tops out at 65,535 × 65,535 pixels.

Perguntas frequentes
CR2 (Canon RAW CR2) is an image format used to store raster graphics — a two-dimensional grid of pixels describing a picture. It is part of the raster & vector images family and designed around a specific trade-off between file size, visual fidelity, and feature support (transparency, colour depth, compression type). Photographers, web designers, and content creators choose CR2 when its particular strengths match the publishing target.

Most desktop photo viewers (Windows Photos, macOS Preview, GIMP, Photoshop, Affinity Photo) open CR2 natively. On mobile, iOS Photos and Google Photos display CR2 in the gallery when supported by the OS. If the format is rare or new, convert to JPG or PNG first — both are universally readable — using our CR2 to JPG or CR2 to PNG converter.

Upload the CR2 to KaijuConverter and pick a target format (JPG, PNG, WebP, HEIC, TIFF, BMP, SVG, PDF). The conversion runs in the browser via ImageMagick and returns a download in seconds. No account or installation required; both input and output delete automatically within two hours.
It depends on the task. JPG is the smallest file size for photographs; PNG is lossless with transparency; CR2 has its own niche that may favour colour depth, animation, or encoding efficiency over one or both of those. For the final web publish, test all three and measure file size plus visible quality on real content.
