Ad Builder

Switching designs keeps your photos, logo, message and link. Each design remembers its own colors, so switching back restores the ones you had. The Event design has no button — the whole ad is clickable, and the tilted sticker carries the event dates. The Issue Promo design puts your photos on the right as tilted magazine covers (the first photo is the front cover, a second one sits behind it) and has no background video.

The typeface of the headline (the title, in the Event design). Default keeps each design's own look. Buttons and the dates sticker keep their design's fonts. Each style is embedded in the ad file (about 20–30 KB), so the ads stay self-contained.

Formats the headline (the title, in the Event design) on every size — use the Aa button on a size to give that size its own. Bold is each design's headline weight by default; in the Event design it needs a font style other than Default. Italic is the real italic for Caslon and a slanted version of the others. Sentence and Title case can't know proper nouns — leave it on “As typed” and type them exactly if that matters. Alignment only moves the text, not the logo or button.

Used for file names in the export.

Auto-resized to keep file weight in check. Add one photo for a static background, or 2–6 to crossfade through them as a slideshow in the animated ad sizes — drag a thumbnail to reorder, that order is the slideshow sequence. The static image sizes (Instagram/newsletter/HubSpot) always use just the first photo. Pick a focal point so the crop looks right at every size:

Off (default): plays through once and settles on the last photo (or the video's last frame), same as the rest of the entrance animation — safely within most ad networks' animation-length policies. On: repeats indefinitely — only applies with 2+ photos or a video.

Plays instead of the photo slideshow in the animated sizes. Each ad file has to stay under 1,000,000 bytes, so the clip is silent and short: up to 8 seconds are kept (set “Start at” before choosing the file to pick which part), and every size gets its own copy cropped to fit and compressed to the space that size has left. “Play” sets how much of the clip each ad uses. The focal point above sets the crop. The photo — or, with no photo, the video's first frame — is still used for the static image sizes. Needs a current Chrome, Edge or Firefox to build it; the finished ads play in any browser that plays WebM, and show the first frame in ones that don't.

Transparent PNG recommended. Every logo you upload is kept in a shared library, and the logos already inside saved campaigns are added to it too — so any campaign can reuse them. Choosing one copies it into this campaign.

Helps legibility on busy photos. Turn off for logos that already have their own background, or that read fine directly on the photo.

One message adapts to every size, shrinking to fit rather than cutting off. Long headline (branded content, story titles)? Press Enter to split it into frames yourself, one line per frame (up to 6) — those breaks are yours to keep, but a line that's still too long for a given size gets sub-split further for that size only, instead of forcing every size to share the exact same lines. Leave it as one line instead and each size makes that same call from scratch: a message too long for a given size's comfortable length splits into frames on that size only, while a size with room to spare keeps it as one — so the same message (typed as one line, or your own breaks) can play as 3 frames on 320×50 and stay simpler on 1080×1350. Either way, the animated ad sizes play frames in sequence — about 2.5s each — and loop continuously back to the first, for as long as the ad is up, independent of whether the photo slideshow loops. The CTA still only enters once, timed to land with that first pass's last frame instead of appearing early, then stays put while the headline keeps cycling. The static image sizes can't animate, so they stack frames as separate lines instead.

Printed on the tilted sticker, in capitals. On the taller sizes it wraps onto two lines. Leave it empty to hide the sticker.

The small sticker on the wide and thin sizes (970×250, 728×90, 320×50, 560×175) has room for about a dozen characters. Leave this empty to reuse the full dates there — they'll shrink to fit.

The serif look uses the Serif font style (a stand-in for the design's Financier Display). Pick another Font style above to change the face. Bold sans switches to a heavy sans headline.

Baked in as the ad's clickTag — see README in the export for ad-server notes.

The three static image sizes (Instagram, newsletter, HubSpot). JPG is typically 3–10× smaller than PNG for photographic ads, with slight loss (90% quality) and no transparency. The animated ad sizes are unaffected.
