icloud mail attachment limit

iCloud Mail attachment limit.

iCloud Mail stops inline attachments at 20 MB and hands you over to Mail Drop above that. Mail Drop is fine when both sides are in Apple Mail, but Gmail and Outlook recipients often see a broken icon and have to click through to a download page. The fix is to skip Mail Drop and paste a plain HTTPS link your recipient's mail client can render however they prefer. Drop the file on quik.space, copy the link, paste it into your iCloud Mail message. The upload widget below is ready.

What is happening

iCloud Mail caps inline attachments at 20 MB. Mail Drop carries up to 5 GB but the link expires in 30 days.

iCloud Mail uses the same SMTP-era convention as everyone else and stops inline attachments at 20 MB. Above that, Apple Mail offers Mail Drop, which uploads the file to iCloud and replaces the attachment with a download link valid for 30 days. The Mail Drop link only renders well in Apple Mail and some compatible clients, which is why recipients sometimes see a broken link.

Common workarounds

Here is what most people try first, and where each option falls short.

Use Mail Drop from Apple Mail
Attach the big file in Mail and accept the Mail Drop prompt.
Downside. Mail Drop links only render reliably in Apple Mail. Other clients sometimes show a broken icon. File lives in iCloud for 30 days.
Compress to fit under 20 MB
Pack into a zip before attaching.
Downside. Already-compressed formats barely shrink. Modern files rarely fit under 20 MB after compression.
Upload to iCloud Drive and share
Drop into iCloud Drive, share the link.
Downside. Recipient may need an Apple ID. iCloud Drive uses your storage quota.
Switch to a transfer service
Use WeTransfer or similar.
Downside. Recipient gets an email-link delivery step that spam filters sometimes eat. Some services require accounts.

The cleaner fix

Drop the file on quik.space, copy the link, paste it into your iCloud Mail message. Recipient opens the link in any browser, downloads the file, walks away. No Apple ID, no Mail Drop quirks, no 30-day iCloud retention to clean up. Free up to 100 MB and supports up to 5 GB on a one-shot upgrade.

The upload widget at the top of this page is the same one on the homepage. Drop the file, copy the link, paste it where you wanted to attach. See pricing for the full table or how it works for the three-step explainer.

What we will not do

We do not read your file. We do not train AI on your file. We do not sell your file. Every upload is encrypted in transit over HTTPS and at rest. The share ID is an 8-character random string with roughly 218 trillion combinations, so the link is practically unguessable. After 72 hours plus a 7-day grace period, the bytes are permanently purged from storage and cannot be recovered.

Frequently asked

Why does Mail Drop sometimes show a broken link?
Mail Drop links render best in Apple Mail. Gmail, Outlook, and other clients sometimes show them as a generic attachment icon, and the recipient has to click through to download.
Does iCloud Mail Drop count against my iCloud storage?
No. Mail Drop has its own quota. But the file expires after 30 days and is not recoverable after that.
Will a quik.space link work in iCloud Mail?
Yes. The link is plain HTTPS and works in any mail client and any browser.
How long does a quik.space link last?
72 hours by default. Pay $2 to extend by 30 more days, renewable.
Is this safer than iCloud Mail Drop?
Similar from a transport angle. From a recipient-experience angle, much better, because the link works in every mail client without Mail Drop quirks.
