Refund Policy

Last updated: February 23, 2026

Simple and Fair

We only charge for credits that are successfully used. If you have unused credits and no longer need them, we'll refund them — no questions asked.

What We Refund

We will refund unused credits only. A credit is considered used when a compression operation completes successfully and the compressed file is returned to you.

  • Unused credits — fully refundable at the original purchase price.
  • Partially used credit packs — the unused portion is refundable.

What We Do Not Refund

  • Used credits — credits that have been consumed by successful compression operations cannot be refunded, as the compute cost has already been incurred.
  • Failed compressions — if a compression fails for any reason, no credit is deducted. You will not be charged for failed operations.

How to Request a Refund

To request a refund for unused credits:

  1. Contact us via the Contact page or email billing@smallest.zip.
  2. Include your account email address.
  3. We will verify your unused credit balance and process the refund within 5 business days.

Refunds are issued to the original payment method.

Processing Time

Approved refunds are processed within 5 business days. Depending on your bank or card issuer, it may take an additional 3–10 business days for the funds to appear in your account.
