Online forms often bounce PDFs over ~10 MB. This preset keeps color so seals and blue ink stay readable, strips only hidden metadata, and warns before you hit Submit on the portal.

Shipping labels, ID scans, and signed affidavits should not be uploaded to a random compress site. Use this page to shrink toward a practical ~10 MB form limit while keeping color so stamps and ink still look intentional — everything runs offline in the browser.
Government and carrier portals already ask for sensitive pages; adding another third-party upload before that step is unnecessary risk.
VeloTools never receives the scan. You compress locally, then upload only to the official portal.
Online forms tied to USPS-style and municipal workflows often reject single-file uploads past roughly 10 MB. Unlike homework modes, you cannot simply force grayscale — a muddy stamp or blue wet signature can fail a human review even when the byte count looks fine.
People respond by crushing quality until seals look blocky, then get rejected for legibility instead of size. The better path is email-like resolution with color kept, plus a warning near 10 MB so you know when to remove extra pages instead of destroying the stamp.
Always read the form’s own help text; some legacy fields sit at 5 MB and need a stronger Screen pass after this one.
| Problem it solves | Online form PDF too large to upload |
|---|---|
| Size check | ~10 MB practical single-file target |
| Color | Kept for seals, stamps, blue ink |
| Hidden data | Metadata stripped; visible pages unchanged |
| Privacy | Local only — upload only to the official portal |
| Not for | PDF/A archival packages |
Unlike LMS grayscale modes, this URL refuses forced gray. We re-encode at email-like resolution, strip metadata that does not help a reviewer, and warn around 10 MB so you know when to delete unused pages.
It will not emit PDF/A. If the checklist demands archival PDF/A, use a dedicated converter after size is under control — do not expect a size tool to invent conformance.
Unlike homework modes, this URL refuses forced grayscale. A muddy stamp can fail a human review even when the file is small enough. We trade a bit of size for color fidelity at email-like resolution, then warn around 10 MB — a ceiling many USPS-related and municipal fields still hint at.
Always read the form’s own help text; some legacy fields sit at 5 MB. When that happens, try Screen on Compress PDF and zoom the signature before submitting.
For school portals instead of government forms, use Canvas, Blackboard, or Moodle. Multi-page evidence packets can be divided with Split PDF.
Browse PDF tools if you need to reorder scanned pages before the official upload.
I keep this page because PDF attachment limits for Usps 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.
