Got a question?
Which tools are available?
Ten tools: merge, compress and edit PDF pages, PDF ↔ Word, PDF ↔ Excel, PDF ↔ JPG/PNG and OCR text extraction. Each tool shows its limits in the job panel.
Where do my files go?
When you start a job, files are sent to our server over an encrypted connection, are only reachable from your session and are deleted when they expire. Early deletion closes access immediately.
Do PDF → Word and Excel keep the original layout?
PDF → Word rebuilds fonts, images, tables and columns into an editable document; complex designs may differ. PDF → Excel extracts detected tables; run OCR first for scanned documents.
Which files can I use?
Depending on the tool: PDF, DOCX, XLSX, JPG and PNG. Password-protected PDFs and Office files with macros or external links are not supported. Size and page limits are shown in the job panel.
