Ranked by privacy, daily limits, and what PDF tasks each tool actually handles well. PDF conversion covers two very different jobs — we pick the right tool for each.
The only PDF converter on this list that never uploads your file. Converts JPG, PNG, WebP, AVIF, HEIC, GIF, BMP, and SVG to PDF — and PDF to JPG, PNG, AVIF — entirely in your browser. Also converts DOCX, XLSX, and other documents to PDF. Unlimited, no account, works offline. Does not do OCR-based PDF-to-Word extraction — use ILovePDF for that.
Dedicated PDF toolkit: PDF to Word, Excel, PowerPoint, JPG, and back. Merge, split, compress, watermark, rotate PDFs. Cloud-based — files uploaded. Free tier with daily limits (typically 2 tasks per hour on free). The most accurate free PDF-to-Word conversion available without a subscription.
Full PDF toolkit (convert, compress, edit, sign). Cloud-based, files uploaded. Free tier: 2 tasks per hour. Excellent interface. Good for users who need occasional PDF-to-Word or merge tasks and don't need daily bulk conversions.
Free open-source desktop suite (Windows, macOS, Linux). Exports DOCX, XLSX, PPTX, ODT to PDF with no upload, no limit, no account. Also imports PDFs as editable Draw documents (limited accuracy). Full office suite — requires installation.
Adobe's online tool converts PDF to Word, Excel, JPG and more. Most accurate PDF-to-Word conversion for complex layouts (tables, columns). Free tier: 2 conversions. Files uploaded. Requires Adobe account. Best when document fidelity is critical and ILovePDF results aren't good enough.
