Frequently asked questions

Short answers to common questions about usage, privacy and support.
Is my file uploaded to your servers?
By default most processing runs locally in your browser. When a server conversion is needed we only keep files temporarily for processing and remove them automatically. See Privacy & Security for details.
Are my files deleted after processing?
Yes - server-stored files are deleted after a short expiration window (typically minutes to a few hours). We do not keep processed files longer than necessary.
Which formats can PDF Converter handle?
Common office formats (DOCX, XLSX, PPTX), images (JPG, PNG, TIFF) and PDF ↔ conversions. Some complex layouts may require manual checking.
