How do I subscribe to Premium?+
Sign in, choose monthly or yearly billing, and continue to Waffo checkout. Premium becomes active after a confirmed production payment. A checkout return URL alone does not activate a subscription.
What is the difference between Basic and Premium?+
Basic includes one introductory successful SKP conversion per signed-in account. Daily check-in adds 1 conversion per Beijing calendar day, up to 3 unused rewards; each expires 7 days after receipt. Premium includes unlimited conversions during an active paid period, subject to service capacity and acceptable use. File-header version checking remains free. Failed or canceled conversion streams do not consume the introductory allowance.
How do daily check-in conversions work?+
Sign in and use Daily check-in in the header. Claim 1 conversion per Beijing calendar day (UTC+8), with at most 3 unused check-in conversions saved. Each reward expires 7 days after receipt. Rewards are used in earliest-expiry order before your introductory conversion. A failed or canceled stream does not deduct a reward. At the cap, use a reward before claiming; reaching the cap does not mark that day as claimed. Premium users can claim too, and active Premium conversions do not use saved rewards.
How much does annual Premium cost?+
Annual Premium costs $48 USD per year, equivalent to $4 per month. It is charged as one annual payment and renews annually until canceled. Twelve monthly payments cost $84, so annual billing saves $36 (approximately 43%). Any applicable tax is shown at checkout.
What file size is supported?+
Each request supports one SKP file up to 100 MiB. The same limit applies to Basic and Premium. A subscription does not bypass file validation, timeouts, or processing capacity.
Which SketchUp versions can I convert to?+
Targets include SketchUp 3–8 and 2013–2026. Targets 2021–2026 share the versionless format, so the actual output header may show a different year. Inspect the result in your intended SketchUp application.
Does Premium include STL, OBJ, or FBX export?+
No. This service converts between SKP version formats. Premium does not add other output formats.
Does unlimited mean simultaneous or instant conversion?+
No. Unlimited refers to conversion count during an active paid period. Shared processing capacity, the 100 MiB file limit, timeouts, and the Acceptable Use Policy still apply.
How do I cancel or request a refund?+
Contact support@skpconverter.online using the email on your receipt and include your order reference. Request cancellation before the next billing date to stop future renewals. A cancellation does not itself refund a payment. Read the Refund Policy for billing disputes and applicable rights.
