SlideSmith — questions, answered

How do I make an Instagram carousel from text?

Paste your text into SlideSmith and it splits into slides on paragraph breaks, measuring real line boxes so nothing overflows. Pick a template, set your accent colour, and download every slide as a 1080x1350 PNG.

Is there a free Instagram carousel maker with no login?

SlideSmith is free with no account, no watermark and no export limit. It runs entirely in your browser, so there is nothing to sign up for and no credit counter — you can make as many carousel posts as you like.

What size should Instagram carousel slides be?

Use 1080x1350 pixels for the 4:5 portrait ratio, which takes the most feed height, or 1080x1080 for square. SlideSmith exports both at exactly those pixel sizes and keeps every slide in one carousel the same ratio.

Can I make carousel posts on my phone in the browser?

Yes — SlideSmith is a web page, so it works in Safari or Chrome on a phone with nothing to install. The editor is touch-sized, and the export hands each slide to your phone's share sheet or straight to your camera roll.

How many slides can one Instagram carousel have?

Instagram allows up to 20 images or videos in a single carousel, and SlideSmith caps its deck at 20 for the same reason. If your pasted text needs more than that, it tells you exactly how many characters did not fit.

Are my photos uploaded when I make a carousel here?

No. Every slide is drawn on a canvas inside your own tab, and the PNG and ZIP files are built there too — no image, no text and no project file is ever sent to a server. The tool never contacts Instagram at all.

What is DMrun?

About SlideSmith

SlideSmith is a free, on-device Instagram carousel maker from shotMod that turns a block of text into designed, ready-to-post slides. Paste a caption, a thread or a set of notes and it splits them into slides on paragraph and sentence boundaries, measuring real line boxes rather than counting characters, then lays each one out on a strict typographic grid. There's no login, no account and no API keys.

Seven hand-built templates — editorial, bold quote, numbered list, checklist, photo and caption, cover with a call to action, and plain minimal — share one 6-column grid, one modular type scale and the same safe margins, so a deck stays consistent no matter how you mix them. You choose the accent colour, the ground and the font pair; slide numbers and the swipe hint are one toggle each. Type that runs long is auto-fitted down to a documented floor and then flagged, never silently clipped.

Everything is drawn on a canvas in your own tab and exported as 1080x1350 or 1080x1080 PNGs, one at a time or as a ZIP in slide order, with a JSON project file you can save and reopen. SlideSmith is part of shotMod, a free hub of Instagram tools by SourceStrong AI. Once your carousel is live, its sibling tool DMrun (dmrun.com) can turn the comments it earns into customers.
