Icons8 subscriptions renew automatically — monthly or yearly, depending on what you chose at checkout. You'll be charged at the start of each billing cycle until you cancel.
What you get with a subscription:
A monthly download quota (varies by plan — see which plan fits your needs)
Access to all formats, including SVG, at any size
No attribution required
Unused downloads carry over to the next month as long as the subscription is active. If you cancel, remaining downloads expire at the end of the billing period — but everything you already downloaded stays yours permanently.
Not sure you want to keep it? You can pause for 1–3 months to preserve your credits, or cancel anytime.
