Batch entire folders
Queue every file at once across 12 batch-capable tools — 6 converters, STL Repair, and 3 optimization tools.
MeshWrench Pro
Stop converting files one at a time.
Batch an entire folder through the same conversion, repair or optimization pipeline you already trust — reuse your settings, and get back to the work that actually needs you.
- ✓ One-time payment, never a subscription
- ✓ 7-day money-back guarantee
- ✓ Still 100% local — nothing you process is ever uploaded
“Need to convert 37 more?”
The free tools handle file #1 perfectly. It's files #2 through #40 that cost you the afternoon.
Every MeshWrench free tool already does its one job at full quality, with no account and no upload — and it always will. Pro exists for the exact moment that job stops being "a file" and becomes "a folder": the same settings, the same fixes, repeated dozens of times.
What you get
Everything in Free, plus the parts that don't scale to a folder.
Reusable presets
Save your repair or optimization settings once and apply them to every batch from then on — no re-configuring per job.
Adjustable concurrency
Run 1 or 2 files at once, tuned to your device — large batches stay responsive instead of freezing your tab.
ZIP + JSON report downloads
Every result, packaged as one ZIP, plus a machine-readable JSON report of exactly what changed in each file.
Ad-free
No ads anywhere, on top of the same local-only privacy every free tool already gives you.
Still zero uploads
Batch mode runs through the exact same on-device Web Worker pipeline as the free tools. Nothing new ever leaves your browser.

Why trust this
No testimonials to take our word for — verify it yourself.
No subscription trap
One payment, one license key, yours forever. Nothing renews, nothing to remember to cancel.
Nothing to take on faith
Open your browser's network tab while batching a folder on Pro. No request will ever contain your file's bytes — same as every free tool.
The same architecture, not a different tier
Pro doesn't route your files through a new, less-tested code path. It's the identical local Web Worker pipeline the free tools already use.

Frequently asked questions
Is this really a one-time payment, not a subscription?
Yes. $39 once. No recurring charge, no trial that auto-converts, nothing to cancel later.
What exactly does Pro unlock?
Batch processing (queue a whole folder instead of one file), reusable presets for repair and optimization settings, adjustable concurrency, ZIP + JSON report downloads, and an ad-free experience — across every batch-capable tool.
Which tools support batch mode?
All 6 converters (3MF/OBJ/GLB/PLY → STL, and STL → OBJ/3MF), STL Repair, and all 3 optimization tools (Reduce File Size, Simplify STL, Triangle Reducer) — 12 tools in total, with more added as new tools ship.
Do my files get uploaded once I'm on Pro?
No — this never changes. Every Pro capability runs with the exact same local-only processing as the free tools. There is no file-processing backend anywhere in this product, Free or Pro.
What if it's not for me?
Email us within 7 days of purchase and we'll refund you — no questions asked. See the guarantee above.

Use "Forgot your license key?" below — enter the email you purchased with and we'll send it to you.
