Official-source PDF upload size limits
Source-linked upload caps for hard-limit forms and portals. Every row points to an official source checked on 2026-06-29; every row stays unverified until the official source also states a policy effective date.
Short answer
Use this as a source checklist, not filing advice. If a portal says 2MB, 4MB, 5MB, 12MB, or 25MB, compress below the cap with headroom and re-check the official upload prompt before submitting.
