Know the difference.
SKP version conversion keeps the model in the SketchUp ecosystem. The key question is which file format your destination can read.
SketchUp 2020 and earlier
Older installations use version-specific formats. A downconversion method needs to support the exact legacy version you want to open.

Download and inspect
Review the resulting model in the destination application. Check its dimensions, geometry, materials, components, and scenes.
Different versions.
The same project.
From studio handoffs to a downloaded component, a little compatibility planning reduces the back-and-forth.
Client & consultant handoffs
Agree on the receiving SketchUp version before sending a project. Keep the original model alongside any converted copy.
Shared design libraries
Check the version requirements of downloaded models before adding them to an existing studio workflow.
Classrooms & older workstations
Identify whether a legacy installation is the source of an opening error, then choose an appropriate next step.
Your model deserves
a proper final check.
Conversion can change the way model features behave. Review a copy in the actual destination version before using it for production.

Answers about SketchUp version conversion, older SKP files, and this website.
What is a SketchUp version converter?
A SketchUp version converter rewrites an SKP model for a different SketchUp file format. It is different from exporting a model to STL or OBJ: the intended output remains an SKP file for use in SketchUp.
Can I convert my SKP file on this website now?
Yes. Choose a SKP file up to 100 MiB, check its file-header version, select a supported target, then convert and download the resulting SKP file. Sign in for one free successful conversion. Further conversions use available daily check-in rewards or active Premium.
Do newer SketchUp files always need downconverting?
No. SketchUp introduced a versionless SKP format in 2021. Compatibility within that format differs from older, version-specific files. Check your exact SketchUp release and update it before assuming the file needs conversion.
Can I downconvert to SketchUp 2020, 2019, 2018, or 2017?
Yes. Supported conversion targets are SketchUp 3–8 and 2013–2026, including 2017, 2018, 2019 and 2020. Targets 2021–2026 share a versionless format. Always review your converted copy in the destination application.
What should I do if SketchUp says the file was created in a newer version?
Confirm the version of your installed application and the model's source version. If you use a supported SketchUp version, install its latest updates. SketchUp also recommends opening the model in SketchUp for Web when an older desktop version cannot open it. Follow the official compatibility guidance linked on this page.
Will materials, textures, and components survive conversion?
That depends on the conversion method and the features used in your model. Keep an untouched source file and review geometry, units, materials, components, tags, and scenes in the destination version. This website does not guarantee lossless conversion.
Does the compatibility checker work on Mac and Windows?
Yes. Use a modern browser on Mac or Windows to select a SKP file, check its header and request conversion. Processing takes place on our server; the header check does not validate the complete model.
Are my SKP files uploaded or stored?
Selecting a file keeps it local until you click check or convert. Each action uploads the full file to our processor. Conversion uses temporary files that are cleaned up after processing; there is no saved model history. See the privacy policy for processing and transport details.
Is SKP Converter free?
Version checking is free without signing in. Each signed-in account gets one free successful conversion; further conversions use available daily check-in rewards or active Premium. Each file must be 100 MiB or smaller. Processing capacity is shared, so busy requests may need a retry. Daily check-in grants 1 conversion per Beijing calendar day, capped at 3 unused rewards; each reward expires after 7 days. Premium costs $7/month or $48/year through Waffo checkout.
Is this an official SketchUp tool?
No. SKP Converter is an independent website and is not affiliated with Trimble or SketchUp. Third-party names and trademarks belong to their respective owners.
