SketchUp version converter: can you open an older SKP?
Can it be saved down?
Current SketchUp saves versionless SKP files for supported versions; it no longer saves to older, unsupported SKP formats. Need a 2017 or 2020 file? Do not assume today's Save As can produce it. Use a current supported version, open the model in SketchUp for Web, or agree an exchange format with the recipient. This page provides compatibility guidance, not an online SKP downgrade.
For a SketchUp 2024-to-2023 handoff, check that both installations are supported and updated before looking for a converter. SketchUp introduced the versionless SKP format in 2021, but that does not guarantee every old installation supports every newer feature. A 2024-to-2017 or 2024-to-2020 request involves a legacy format: SketchUp's current Saving a Model documentation explicitly says saving to older, unsupported versions is no longer available.
The procedure that works
- 1Ask for the recipient's exact SketchUp release, update level and required deliverable: an editable SKP, a review model or exported geometry.
- 2For supported installations, update SketchUp, keep the original model and use File → Save As to save a separate versionless SKP copy. Have the recipient open that copy; Save As is not a target-year downgrade in current SketchUp.
- 3If the recipient uses SketchUp 2017 or 2020, first agree whether they can use a supported version or SketchUp for Web. Do not promise a 2017/2020 SKP from the current Save As dialog.
- 4If an older installation offers a target-version option, treat that as a release-specific legacy workflow, not a current supported feature. Verify it on a copy in the recipient's actual release before relying on it.
- 5If native compatibility is unavailable, agree an export format that both installations support. Reopen the exported file and check dimensions, geometry and materials; an exchange file is not an older editable SKP.

What the file loses
- • Versionless file compatibility does not guarantee that an older installation or extension can use every newer feature. Check the recipient's software and required model behavior.
- • Do not assume renderer settings, extension objects or external assets transfer. Confirm plugin compatibility and package required textures separately.
- • Exchange exports may omit scenes, tags, component behavior and application-specific data; what survives depends on the chosen format and export settings.
- • Keep the original native SKP and compare the handoff copy against it before issuing a deliverable.
Which SketchUp handoff should you use?
The versionless format began in 2021. Current support status and installed updates still matter; a shared format is not a promise of full feature compatibility.
| Supported SketchUp releases | Versionless SKP | Update both installations; send and test a separate copy |
|---|---|---|
| SketchUp 2017 or 2020 recipient | Legacy SKP requirement | Current SketchUp cannot save to older unsupported formats |
| Older desktop Save As option | Release-specific legacy workflow | Only rely on a target version actually offered and tested |
| SketchUp for Web | Open the model with a current web app | An alternative to an unsupported desktop installation, not a legacy SKP converter |
| Agreed exchange format | Geometry handoff | Check import support and losses; not a native SKP downgrade |
Questions
Can SketchUp 2024 files open in SketchUp 2023?
SketchUp introduced versionless SKP in 2021. Its current documentation guarantees compatibility between supported versions, so check support status and updates rather than assuming any old installation works. Test the actual model and its extensions on the recipient's installation.
Can I convert SketchUp 2024 to 2017 or 2020?
Current SketchUp no longer saves to older, unsupported SKP formats. An older desktop release may have a target-version option, but that is a legacy, release-specific workflow requiring testing. Otherwise agree a supported SketchUp version, SketchUp for Web or an exchange deliverable.
Is this an online SKP version converter?
No. This page explains supported compatibility and handoff options; it does not upload or rewrite SKP files. Saving a model in current SketchUp produces versionless SKP, not a selected legacy year.
Will scenes, components and textures survive?
Test those items in the recipient's installation. Native SKP compatibility does not guarantee every newer feature or extension works; exchange formats can lose scenes, tags and component behavior. Keep the original model and check the deliverable.
What should I do about the newer-version error?
SketchUp recommends a current supported release, or SketchUp for Web if you do not have a subscription. If you already use a supported release, update it to the most recent version. Do not assume current Save As can write an unsupported legacy format.
