The dates that are
not negotiable.

USPS — send-by dates for delivery before December 25

For the contiguous United States (the lower 48 states):

Alaska, Hawaii, Puerto Rico and the US territories get a different table, and the first row is the one people miss: Ground Advantage to or from Alaska, Hawaii, Guam, the Northern Mariana Islands, American Samoa and the US Virgin Islands expects a 10-day service or more, so the send-by date is earlier. USPS also notes that Hanukkah falls early this year (December 4–12, 2026), so if a gift is for that holiday, plan around the earlier date rather than Christmas.

USPS — international and military

• First-Class Package International and Priority Mail International: Wednesday, December 9, 2026 for every international destination listed (Africa, Asia/Pacific, Australia/New Zealand, Canada, Caribbean, Central and South America, Europe, Mexico, Middle East).
• Priority Mail Express International: Wednesday, December 16, 2026.
• Military mail is earlier again: Ground Advantage to APO/FPO/DPO addresses goes by November 4, First-Class and Priority by December 9, Express by December 16.

FedEx — last day to ship

FedEx publishes a grid keyed on transit time, which is more precise than a single date. For delivery by December 24, 2026:

Two operational details: FedEx offices are closed December 24–25 and December 31–January 1, and international deadlines do not include time for customs clearance, so add transit days for anything outside a major city.

UPS — the two closure days people miss

UPS is closed on New Year's Day, MLK Day, Memorial Day, July 4, Labor Day, Thanksgiving and Christmas. For this season that means:

• Thursday, November 26 — Thanksgiving: UPS holiday. UPS Store locations may be closed.
• Friday, November 27 — the day after Thanksgiving: also an observed UPS holiday, so no UPS Ground pickup and UPS Store hours may be reduced.
• Thursday, December 24: UPS pickup for Air and international Air services only, and only if prearranged by December 18. No UPS Ground pickup.
• Thursday, December 31: Air and international Air pickup only if prearranged by December 28. No UPS Ground pickup, and no UPS Ground delivery.

UPS Express Critical stays available year-round through Marken, including on those days. The general rule from UPS is the one worth keeping: allow extra time in the busy period, because last-minute changes are what cause missed deliveries.

The two dates that decide it

Most of the tables above are the same every year, and the same mistake gets made every year too.

1. The send-by date is not the same as the last pickup. A carrier can accept a package on December 20 and still miss Christmas if the service is Ground. The date that matters is the one for your specific service, from the carrier's own table.
2. Retailers cut off earlier than carriers do. A retailer has to receive, pick, pack and hand off the parcel — so its own order cutoff is days before the carrier's. Those dates live on the retailer's page, not the carrier's.

To know how many days you actually have left, the time duration calculator gives you the count from today to any date — and it is worth doing it now rather than in December.

The file side: what you are actually shipping

A holiday shipment is usually a PDF, not a photograph: a shipping label, a packing slip, a returns policy, a gift card, a catalogue. Those files get emailed, and they get emailed badly.

• Shipping labels and packing slips are generated as PDFs and attached to an order confirmation. A multi-page label pack from a print driver can be several megabytes, and the email carrying it is the part that gets rejected. Our Compress PDF tool shrinks it in the browser, so the document never reaches a third-party server to be squeezed.
• Gift cards and product photos are images, and the ones that come from a supplier are frequently 2–5 MB each. Our image compressor handles the whole batch, with a ZIP download at the end. For a form that wants a specific ceiling, the compress to 100 KB and to 500 KB tools hit an exact target — our measured numbers for a 4.6 MB image are in the Black Friday 2026 guide.
• Seasonal catalogues are the worst case. A 40-page price list exported from a design tool is frequently 5–10 MB, and it gets attached to email and uploaded to a portal in the same week. Compress it once, then reuse the small file everywhere.

All of this runs locally, which matters for the order confirmation and the packing slip specifically — those documents carry customer names and addresses, and there is no reason for them to be uploaded to a converter to get smaller.

What this guide is not

• Not a promise. Every carrier says the same thing: actual delivery depends on origin, destination, acceptance time and conditions, and schedules can change. This is the published schedule, not a guarantee.
• Not a retailer list. Order cutoffs, in-stock handling and shipping minimums are set per retailer and are often stricter than the carrier's.
• Not a tool for tracking. We do not track packages. For that, the carrier's own site is the source.
