The .seal format
Sealshot saves captures as .seal packages: the original, untouched pixels
plus your annotations, stored together in one file. Recordings use the same
container — a video .seal holds the movie plus its metadata.
Why a custom format?
Section titled “Why a custom format?”Flat image files bake annotations into the pixels — once you export, an
arrow can never be moved and a blur can never be adjusted. A .seal file
keeps everything editable: reopen it next month and rearrange, restyle, or
remove any annotation.
What’s inside
Section titled “What’s inside”Alongside the original pixels and the annotation list, a .seal carries
the capture’s own intelligence: the recognized OCR text (which powers
library search), the automatic summary,
Smart Keywords, and your tags, capture provenance (which app, when), and
cached Extract Structured Data
results.
The editing state rides along too: any
inserted images, the
enhanced and
background-removed alternates of the base image (with which one you were
showing), crop and focus area, and a
ready-made composite and thumbnail so previews don’t have to re-render.
Move a .seal to another Mac and all of it comes along.
With Enhanced Security on, the package contents are encrypted at rest.
Exporting
Section titled “Exporting”When you need a standard file, export from the editor: a flattened PNG
for images (⌘S), .mov/.mp4 for recordings, or an encrypted
.sealshare package for sharing — see
Sharing & export. The .seal original stays
intact, so you can always re-export differently later.
