Tools
Prep
Crop, compress, convert, mark.
Drawing grid
For sketching, murals, and teaching — not for posting tiles.
Pixel grid
A reference, not a filter pack.
Image crop
Do this before a split if the subject sits on an edge.
Letterbox
When you cannot lose a logo or a limb.
Image compressor
Run this on tiles if a ZIP is too heavy to upload.
HEIC to JPG
Most grid tools need a bitmap. Start here if the file will not drop.
Watermark
Brand a set before you post. We will not remove third-party watermarks.
Remove EXIF
A local pass before you post a home or a child.
Batch convert
Normalize a set before you compose or split.
Highlight covers
Same studio, round tiles.
App Store screenshots
Use this when the listing needs a set, not a raw phone capture.
Colors from a grid
A border color that already exists in the photos.
