Export numbered PNGs

joli.studio does not publish for you: it hands you files. They still have to be the right size, in the right order, and named so you can find them again in six months. That is what the export is for. To publish, the simplest path is still the Publish button, which hands you these same files one step at a time (see publish a post); the export is there when you only want the files.

Exporting

1. Open the post in the slides editor

   Export lives in the toolbar, top right, in the menu of the Publish button. The shortcut Ctrl+E (or ⌘E on a Mac) runs the recommended delivery for the post’s platform straight away, without opening the menu.

2. Or open the menu

   The chevron next to Publish drops the menu open. At the top, the post’s platform: “Publish on Instagram”; further down, the Export section.

3. Choose “Lossless PNG images”

   They sit under Other formats. Every slide becomes a PNG, downloaded separately, in order.

What the menu offers

• Publish step by step, which opens the publish window, and Mark as published, when the post is already live.
• In the Export section, ZIP Instagram or PDF LinkedIn — the recommended delivery, the one behind the shortcut, with its summary: “Numbered JPEGs, caption, alt text and instructions” or “PDF document, one page per slide”. For a LinkedIn carousel, the archive sits right below: PDF, caption and instructions (.zip).
• Other formats, a submenu:
  • JPEG images, one per slide — the same images, as JPEG, without an archive;
  • Lossless PNG images — PNG, when you want maximum quality or a perfectly clean flat background;
  • PDF (one page per slide) — offered as soon as the post has more than one slide and the platform doesn’t already deliver a PDF.
• Finally, the Copy section: The caption and hashtags, The hashtags, The alt texts.

The numbering

Every file carries its rank on two digits, then the post title cut short: 01-3-mistakes-that-ruin-a-baguette.jpg, 02-…, 03-… Sorted by name, a folder is therefore sorted in slide order.

The project, the date, the platform and the format are not repeated on every image: they sit on the delivery itself and in the archive’s manifest.json. Repeating them produced sixty-character names where only the last two digits told the slides apart.

Separate files or an archive

The PNG and JPEG exports download files one by one. The ZIP archive holds everything needed to publish: the numbered images, caption.txt (the caption and its hashtags), alt-text.txt when the post has alt text (one line per image, with its file name), a README.txt that reminds you in three lines how to publish on that particular platform, a manifest.json and an AGENTS.md.

Handing publishing over to an agent

joli.studio doesn’t publish for you, but the archive is written so that an agent can — an assistant that takes over your browser, for instance. Give it the ZIP: AGENTS.md tells it what to do and in which order, and manifest.json gives it everything it has to enter.

• The account: the platform handle, taken from your brand. If the browser is logged in to another account, the agent stops.
• The time: the post’s planned date, in the project’s time zone. If it is still ahead, the agent schedules the post when the platform allows it, or asks you.
• The steps: where to start, then the platform’s own steps — crop to keep, alt text, LinkedIn document title, Pin title and description.
• The stops: a draft, a blocking review point, an AI-written testimonial not yet checked or an image that is too heavy, and the agent doesn’t publish; it tells you why.
• The way back: once the post is live, the agent returns to the post in joli.studio, picks Mark as published from the Publish menu and pastes the link. Tracking starts.

The dimensions

They come from the aspect ratio chosen for the post, not from the export: 1080 × 1350 at 4:5, 1080 × 1080 at 1:1, 1080 × 1920 at 9:16, 1920 × 1080 at 16:9, 1000 × 1500 at 2:3 for Pinterest.

Text posts and animations

A text post, a thread or a poll is copied: its editor has the same Publish button, whose menu offers Copy text, Copy thread or Copy poll (⇧⌘C), with a post-by-post copy for threads. The same menu offers Export to publish (.zip): one file per post, the post’s images, the poll in manifest.json, and the same instructions. Once rendered, an animation downloads as an MP4 (Export the MP4, ⌘E, in the same menu) or as a ZIP to publish, with its caption.
