How KEY turns into JPG: slide-canvas rendering

Painting happens slide by slide: each KEY slide's text, charts, and artwork are composed onto a JPG canvas. Speaker notes, transitions, animations, and editable masters never enter that still image and need checking in the source deck. Keynote packages are traversed for themes, masters, slides, builds, masks, charts, notes, fonts, and media before translating into another presentation system. JPG output is always opaque and lossy, so judge it at high-contrast edges, gradients, fine texture, orientation, and any damage accumulated from repeated encoding.

Source material - An Apple Keynote presentation package containing slides, themes, builds, notes, charts, and media. Rendered deliverable - Lossy JPEG-compressed pixels optimized for photographs and broad compatibility.

Deciding when KEY to JPG is the right conversion

Use JPG for slide thumbnails, review images, or a destination that only accepts pictures. Keep KEY when presenting, revising masters, reading notes, or playing embedded media.

What changes between the KEY model and the JPG deliverable

JPG is a lossy destination, so judge the converted image, motion, or sound directly instead of trusting matching dimensions or file size.
Metadata handling differs between KEY and JPG; do not assume every application-specific field carries across untouched.

Checking the JPG result before you trust it

BEFORE

Record the KEY evidence before conversion

Present the result in the destination app and inspect aspect ratio, masters, fonts, builds, notes, charts, audio, and video.

AFTER

Test the JPG file in its receiving workflow

View text edges, faces, gradients, and high-contrast detail at the intended display size.

What the KEY source carries and the JPG output demands

KEY

What can fail when KEY presentation format is interpreted

PowerPoint-oriented output may change Keynote fonts, builds, transitions, masks, charts, and embedded video.

JPG

What JPEG image cannot safely promise

Repeated encoding introduces ringing or blocks, and transparent areas must become opaque.

ENGINE

How the JPG writer handles this route

The writer builds lossy JPEG-compressed pixels optimized for photographs and broad compatibility and labels the result as image/jpeg. The receiving application - Not the extension alone - Is the final compatibility test.
