Storage is not the problem — attachment and preview are. This page locks mild Web quality so SharePoint/OneDrive PDFs stay under common mail ceilings when someone demands a direct file.

OneDrive and SharePoint store enormous files without complaint, so the real trouble starts when someone insists on a direct attachment and a mail ceiling bounces it. This page runs a mild Web pass toward a 25 MB mail-path check, all in the browser, so the document never visits an outside compressor.
The file is re-encoded in tab memory and never reaches our servers. You download the lighter copy and either re-upload to OneDrive or attach it wherever the mail cap applies.
Annotations are preserved here because these office documents frequently carry review comments, and the mild profile keeps them while shedding export bloat.
Nobody hits a wall putting a PDF into OneDrive; the service will hold it comfortably. The failure appears one step later, when a recipient refuses a link and demands a direct file, and the mail client rejects anything past a common 25 MB attachment ceiling.
Export bloat is what pushes an otherwise ordinary office PDF over that mail line. A mild Web pass trims the waste so the same document can travel as a plain attachment when a link simply will not do.
This URL is built for that specific hand-off: OneDrive keeps the master, and a lightly compressed copy satisfies the person who wants a file in their inbox rather than a shared link.

Since storage is never the issue, this profile stays mild — quality 74 with annotations intact — because the only job is clearing a mail ceiling for someone who refuses a link. There is no reason to crush an office document that OneDrive would host untouched.
If the recipient will accept a shared link after all, skip the attachment entirely and send the OneDrive URL. The compressed copy exists purely for the case where a direct file is non-negotiable.
The quirk this page solves is social as much as technical: OneDrive can store the file, but a recipient sometimes insists on a direct attachment, and mail caps near 25 MB then bite. A mild pass bridges that gap without degrading the office original.
For the actual mailbox send, pair this with the Outlook page, whose ~20 MB consumer habit is even tighter. Its cloud sibling the Box page keeps a larger comfort zone for hosted shares, and the Google Drive page stays milder near ~100 MB.
Oversized decks travel better once split with Split PDF, and a firmer squeeze is available on Compress PDF when a mail cap is unusually strict.

I keep this page because PDF attachment limits for Onedrive 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.
