Sobre os arquivos TIFFComparativo de vantagens
SR2 Vantagens
- Full Sony Alpha early-era sensor data preserved.
- Supported by major raw processors.
- Metadata includes Konica Minolta pre-Sony era compatibility.
TIFF Vantagens
- Lossless by default — no generation loss on successive edits and saves.
- Supports any bit depth (1 to 32 bits per channel), any color model, any number of channels.
- Extensible tag system means vendor-specific data survives alongside standard tags.
- Multi-page containers are perfect for scanned documents, faxes, and DICOM-like stacks.
- Industry-standard for archival, museums, scientific imaging, and high-end print prepress.
Limitações
SR2 Limitações
- Transitional format — limited to 2006-2008 bodies.
- Superseded by ARW.
- Proprietary with no public spec.
- Essentially legacy — no new content.
TIFF Limitações
- File sizes are huge compared to JPEG/WebP/AVIF — often 10-30× larger.
- Not a web format — no browser displays TIFF natively.
- Ambiguous spec areas mean some TIFFs only open correctly in the tool that created them.
- Weak animation support — designed for still imagery.

Perguntas frequentes
SR2 (Sony RAW SR2) 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 SR2 when its particular strengths match the publishing target.

Most desktop photo viewers (Windows Photos, macOS Preview, GIMP, Photoshop, Affinity Photo) open SR2 natively. On mobile, iOS Photos and Google Photos display SR2 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 SR2 to JPG or SR2 to PNG converter.

It depends on the task. JPG is the smallest file size for photographs; PNG is lossless with transparency; SR2 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.
