FAQ

Before you put a file in.

Do local tools upload my files?+

No. Tools labeled Local run entirely in your browser and your file is not uploaded to us — the few that also offer an optional cloud path (large files, legacy formats, cloud engines) mark it clearly on the page.

Which tools use the cloud?+

OCR, Office conversion, and heavy jobs. They are labeled clearly, encrypted in transit, and results are kept for 24 hours and then automatically deleted (nothing is stored for anonymous use). See our Privacy page for details.

Can I cancel anytime?+

Yes. Cancel with one click and keep access until the paid period ends. 14-day money-back on first subscription · Refunded to your original payment method in 3–10 business days · Cancel anytime.

Can I get a business invoice?+

Yes. Add your company and VAT or Tax ID at checkout or in Billing.

Have a document to finish?
