Architecture docs and design PDFs pinned to a Confluence page often describe systems that should not visit an outside compressor first. This page trims the file in the browser with a mild Web preset so a 10 MB embed stops stalling the editor, and the document never leaves your session.
The re-encode happens in tab memory and never touches our servers. You download the lighter PDF and attach or embed it in Confluence yourself.
Annotations are stripped by default because a wiki embed is usually a reference artefact rather than a live redline, keeping the attached copy lean for everyone who loads the page.
Confluence Cloud pages feel sluggish once an attached or embedded PDF pushes past roughly 10 MB, especially when a space is full of macros and the editor tries to render a preview. Readers open the page, wait, and lose the thread.
Teams work around it by pasting screenshots into the body, which fragments the diagram and defeats page search. A mild Web pass keeps a single embeddable PDF that opens without freezing the editor.
The issue is preview responsiveness rather than a hard rejection, so the goal is a file light enough that the macro renders promptly on a colleague’s laptop.

|---|---|
| Size check | ~10 MB embed target |

| Annotations | Stripped for a lean wiki artefact |
| Privacy | Browser-only before the Confluence attach |
| Sibling pages | Jira · Notion |
Wiki content is read in a narrow column, so a mild Web preset that empties export bloat is enough to make an embed feel instant. The quality sits slightly softer than a mailbox target because on-page rendering, not print fidelity, is the job.
Keep the pristine master elsewhere and let Confluence hold the readable copy. Overwriting your only lossless export with a wiki-optimised embed is the kind of shortcut that hurts a diagram later.
The practical 10 MB line on Confluence is about editor responsiveness rather than a blunt cap, so the aim is a prompt-rendering embed, not the smallest possible file. That focus separates it from a mailbox or LMS crush.
Its Atlassian sibling is the Jira page, which shares the ~10 MB neighbourhood but targets ticket attachments. For product-doc embeds in a different wiki, the Notion page tunes for a tighter in-page preview.
Long architecture specs embed more smoothly once you divide them with Split PDF, and one measured pass on Compress PDF handles a stubborn chapter.
Reorder or merge sections before embedding from the wider PDF tools catalogue.
I keep this page because PDF attachment limits for Confluence kept failing with upload tools or generic presets. Here you pick the Screen/Web preset that fits the channel, compress locally, then attach. Limits and architecture are documented in Lab Notes — this URL is a micro-instrument for one job, not a keyword clone.
