Shoot once.
Export every size.

A quiet, local image workflow for people who shoot the same setup every day.

Drop photos into a folder. SizeFold processes every new one to all the sizes you need — and moves your originals to a safe archive only after every output succeeds.

SizeFold processing a product photo into a square output

Your folder is the workflow

No importing, no library to build. Point SizeFold at a folder and it takes care of the rest.

📥

A folder is your inbox

Open your shoot folder and every new photo is already queued. Run the batch and the folder clears itself — done shots leave the inbox, so you always know what's finished.

📐

One photo, every size

Amazon 1:1, YouTube 16:9, Stories 9:16, plus 4:3 and 3:4 — turn on the configs you need and one run outputs them all, each filed in its own folder with its own crop, size, and color.

🔒

Verify first, then archive

Every output is written and verified before a single original moves. If anything fails, your original stays exactly where it was — nothing is moved until its outputs are safely written.

No AI. No tokens.
No monthly bill.

SizeFold does one job, on your machine, forever. Nothing to log into, nothing to upload, no credits to top up, no process humming after you quit. You bought a tool — not a subscription that dies the moment you stop paying.

Buy once. Use forever. Own it.
