My file is too large

The limit

15 MB per doc. That's the whole raw body — the Markdown or HTML you paste, or the file you drop, counting every inline image and asset baked into it. Not a page, not a project: one document, 15 MB. Most write-ups, specs, and HTML pages sit well under it, so if you're over, something heavy is embedded.

Why there's a cap

Two reasons, both in your favor. Every doc is served from Cloudflare's global edge, and a lean document loads fast from anywhere — a 15 MB page doesn't. And every doc is sanitized on ingest before it's published; keeping bodies bounded keeps that pass quick and predictable. The cap is what makes a paste-and-share link feel instant.

How to get under it

Work down this list — the first one usually does it:

• Compress or resize images before embedding. A full-resolution photo or screenshot is often 1–4 MB on its own, so a handful of them clears 15 MB fast. Drop each to a sensible display width and re-export as compressed JPEG or WebP before it goes into the doc.
• Strip large data: URI images and link them instead. If your HTML has a giant data:image/png;base64,… blob inline, base64 adds roughly a third to the original size, and a few of those strings can be most of the 15 MB on their own. Host the images somewhere on https and reference them by URL — the doc drops to a few kilobytes. See how to host an AI image.
• Paste the key section, not the whole thing. If you're sharing one part of a long document, share that part. A tight page also reads better and its scroll and heatmap data is more useful.
• Remove unused assets. Fonts you don't use, duplicated images, dead markup — clear them out.
• Big media stays out for now. Audio and video hosting isn't supported yet; you can't get a 40 MB clip under the cap by trimming. Link to where it already lives instead.
