Yes. FastConvertTools is free to use with no account required. We fund the site through advertising so you can convert files without a paywall.
Files are transferred over HTTPS to our conversion partner for processing and are typically deleted from their servers within about one hour. We do not use your documents to train models or build marketing lists.
PDF and video tools accept up to 100 MB per file per job unless the upload area states otherwise. Image and text tools may use browser limits instead of a fixed cap.
Any modern device with a current browser works. Phones and tablets can upload from the gallery or files app; desktops support drag-and-drop. Disable aggressive ad blockers only if they block the conversion script—never disable HTTPS.
You control the start index, but hidden PDF pages or unnumbered front matter can confuse readers. Align start numbers with your table of contents manually.
Page numbers guide readers through long briefs, board packs, and training manuals. Courts and arbitration rules often require consistent numbering on filed PDFs. Unlike word processors where headers are native, PDFs need overlay text drawn on each page surface. Position matters: bottom center is traditional, while top right suits binders with tab cuts. Starting at zero versus one affects sync with existing tables of contents—set deliberately. Numbering does not change internal PDF page labels used by some printers; test on the device you will use for hardcopy. Combine with merge after combining chapters so numbering runs continuously. For drafts, watermark instead of formal numbering to avoid confusion with final editions.
FastConvertTools focuses on straightforward workflows: upload or paste, convert, download, and move on with your day. Whether you are a student fixing one assignment, a freelancer delivering client assets, or an office administrator unblocking an email attachment limit, you get clear steps on this page and predictable limits before you start. When results must be perfect, always keep an original copy and spot-check the output against your source—automated conversion saves time, but human review still wins for high-stakes documents.
