About formats

PICT is a metafile graphics format created by Apple Computer as the native graphics format for the Macintosh, debuting alongside the original Mac in January 1984 and remaining central to Mac OS graphics until the transition to Mac OS X. PICT files record a series of QuickDraw operation codes (opcodes) that reproduce the image when replayed through the QuickDraw graphics engine: operations for drawing lines, arcs, rectangles, rounded rectangles, ovals, polygons, regions, text strings, and pixel maps (bitmaps). This opcode-based approach means PICT files are not simply pixel grids but rather programmatic descriptions of how to draw the image, combining resolution-independent vector elements with pixel data in a unified stream. The PICT 2 revision, introduced with the Macintosh II and Color QuickDraw in 1987, extended the format to handle 24-bit color, multiple pixel depths, extended color spaces, and embedded JPEG and PackBits compressed data. PICT was integral to the Macintosh user experience: system clipboard operations (Copy/Paste), screen capture, printing, and inter-application data exchange all used PICT as the common visual representation. One advantage is historical comprehensiveness: PICT files from the classic Mac era capture both the visual output and the drawing methodology of Mac applications, preserving not just the image but the QuickDraw operations that produced it — valuable for understanding the visual computing paradigm of early Macintosh software. The format's extensive use in desktop publishing during the DTP revolution of the late 1980s provides another dimension of historical importance. PICT files are readable by macOS Preview, ImageMagick, XnView, LibreOffice, and GraphicConverter.
Developer: Apple Computer
Initial release: 1984
RGBA is a raw (headerless) image format that extends the RGB color model with a fourth channel for alpha transparency. Each pixel is stored as four consecutive sample values — red, green, blue, and alpha — written sequentially in scanline order with no container structure, headers, or compression. The alpha channel specifies opacity for each pixel independently: a maximum value means fully opaque, zero means fully transparent, and intermediate values produce semi-transparency. Like its three-channel counterpart, RGBA files require the image dimensions and bit depth to be specified externally since the raw data stream contains no metadata. The format supports 8-bit (four bytes per pixel, 32-bit total), 16-bit, and floating-point channel depths. In compositing workflows, the alpha channel enables layering operations where foreground elements are blended over backgrounds according to their per-pixel opacity — the mathematical foundation for all modern image compositing, described by Porter and Duff in their seminal 1984 paper on digital compositing. One advantage is direct framebuffer compatibility: modern GPU hardware natively processes 32-bit RGBA pixels, so raw RGBA data can be uploaded to texture memory or written from render targets without any format conversion, critical for real-time graphics applications and game engines. The format's simplicity in representing transparent images provides another practical benefit — scientific visualization, medical imaging, and overlay rendering can produce raw RGBA output that any downstream tool can consume without needing a common container format. RGBA files are handled by ImageMagick, FFmpeg, and various graphics and compositing tools.
Initial release: 1990

Frequently Asked Questions

Why convert PICT to RGBA?

Apple discontinued PICT support years ago. Converting to RGBA future-proofs your classic Mac images in a format that current software understands.

Which apps support RGBA format?

GIMP, Blender, IrfanView, and 3D rendering software. RGBA adds transparency channel support to the SGI format.

Will the image quality change?

Image data is transferred faithfully from PICT to RGBA. The conversion itself does not degrade or enhance the original pixel information.

Are my files secure during conversion?

All file transfers use encrypted connections. Uploaded PICT files are deleted after processing, and RGBA outputs are purged within 24 hours.

Do I need to install anything?

No — the entire conversion runs in your web browser. There is nothing to download or install on your computer or phone to convert PICT to RGBA.

Where can I upload PICT files from?

You can upload from your local device, Google Drive, Dropbox, or paste a direct URL. Convertio pulls the PICT file from any of these sources.
