About formats

AFF (Acorn Draw) is a vector graphics file format native to Acorn Computers' RISC OS operating system, introduced with the Draw application bundled in RISC OS 2 in April 1989. The Draw application shipped as a standard component of every RISC OS installation, providing users with a capable vector illustration tool at no additional cost. AFF files store vector objects as a sequence of tagged data blocks, each containing object type, bounding box, and type-specific data — supported objects include paths with straight lines and Bezier curves, text objects with font references, sprite (bitmap) objects, groups, and tagged objects for application-specific extensions. Path objects use cubic Bezier curves with move, line, and curve elements, supporting variable line widths, join styles, dash patterns, and flat color fills. The coordinate system uses RISC OS draw units at 1/180 inch resolution, providing precision for both screen display and print output. One advantage is the straightforward binary structure — the tagged block architecture makes AFF files simple to parse and generate programmatically. Native operating system integration is another strength: RISC OS renders Draw files natively in its desktop environment, treating vector graphics as first-class objects alongside bitmaps. While Acorn Computers ceased operations in the late 1990s, RISC OS continues under active open-source development, and AFF files remain supported through the platform's drawing applications and conversion utilities.

JFIF (JPEG File Interchange Format) is the standard file format specification for storing JPEG-compressed images, published by Eric Hamilton at C-Cube Microsystems in version 1.0 in 1991 and updated to version 1.02 in 1992. While the JPEG standard (ISO/IEC 10918-1) defines the compression algorithm — the discrete cosine transform, quantization, and entropy coding that convert pixel data into a compact bitstream — it does not specify a file format. JFIF fills this gap by defining a minimal container that wraps the JPEG bitstream with the metadata needed for interoperable display: pixel aspect ratio, resolution units (DPI or dots per centimeter), color space specification (YCbCr using CCIR 601 conversion from RGB), and an optional embedded thumbnail. The JFIF container is identified by an APP0 marker segment at the start of the file containing the ASCII string 'JFIF' and a version number. Nearly every JPEG file in existence conforms to the JFIF specification — when people refer to a 'JPEG file,' they almost always mean a JFIF file, even if the extension is .jpg or .jpeg. One advantage is universality: JFIF's simplicity and early publication date (predating competing proposals like EXIF) meant it was adopted by virtually every software and hardware platform as the baseline JPEG file format, establishing the interoperability that made JPEG the world's most widely used image format. The specification's deliberate minimalism is another strength — by defining only the essential metadata for correct display and leaving room for application-specific extensions via additional APP markers, JFIF proved extensible enough to accommodate EXIF camera data, ICC color profiles, and XMP metadata without breaking backward compatibility.
Initial release: 1991

Frequently Asked Questions

Why convert AFF to JFIF?

AFF requires extinct software. JFIF is the most common JPEG file interchange standard — the format you see in everyday photos and web images.

What opens JFIF files?

JFIF is standard JPEG. Every operating system, browser, and photo viewer opens JFIF files natively — no extra software needed.

Is JFIF the same as JPG?

JFIF defines the standard JPEG file format. In practice, JFIF and JPG files are interchangeable and open in the same applications.

Is the conversion free?

Yes — free for all users without account creation. Premium plans are optional.

Is my AFF file safe during conversion?

Uploaded AFF files are deleted immediately after conversion. JFIF output files are removed from servers within 24 hours for your privacy.
