We tested the leading tools on the market to create this list of the best PDF converters for 2026. Read on to discover our top picks.
The best PDF converter in 2026 is Lido. In our testing across invoices, contracts, reports, and forms, Lido was the only tool that accurately extracted structured data from varied PDF layouts and delivered clean, usable output without requiring templates, training data, or developer integration. For context on the extraction technology that powers reliable PDF conversion, this primer on data extraction is worth reading first.
Lido is the most capable PDF converter we tested. It handles every document type we threw at it and delivers structured output without requiring templates, coding, or manual cleanup.
Adobe Acrobat Pro is a reliable choice for occasional manual PDF conversion on clean documents. It lacks automation and struggles with complex layouts, making it better suited for individual users than teams with volume.
Smallpdf is the easiest way to convert a simple PDF if you only need it occasionally. It cannot reliably handle scanned documents or complex layouts, so it is strictly a lightweight option for simple conversions.
iLovePDF is the most affordable browser-based PDF converter for simple tasks. It covers the basics well but lacks the extraction accuracy and automation needed for complex or high-volume workflows.
Nitro PDF Pro is a solid desktop option for business users who need both PDF editing and conversion in one tool. It handles native documents well but falls short on scanned document accuracy compared to AI-powered alternatives.
PDF2Go is a serviceable free tool for quick, simple PDF conversions. It lacks the accuracy and features needed for anything beyond basic single-page documents, but for zero-cost occasional use it gets the job done.
Zamzar is useful when you need to convert between obscure file formats, but its PDF conversion quality lags behind dedicated tools. It works for quick one-off conversions where formatting accuracy is not critical.
Join hundreds of teams growing faster by automating the busywork with Lido.
Document type: The most important factor is whether your PDFs are native (digitally created) or scanned. Free browser tools like Smallpdf, iLovePDF, and PDF2Go only work reliably on native PDFs. If you process scanned documents, you need a tool with built-in OCR like Lido or Adobe Acrobat Pro.
Output format: Most tools handle PDF to Word and PDF to Excel. If you need structured data extraction rather than simple format conversion, Lido is the strongest option. For basic format swaps, browser-based tools like Smallpdf or iLovePDF are sufficient. If your primary need is spreadsheet output, see our guide to the best PDF to Excel converters.
Volume and automation: For occasional manual conversion, Smallpdf or Adobe Acrobat may be enough. For automated workflows processing hundreds of documents, you need a tool with API access or built-in automation like Lido.
Accuracy requirements: Simple single-column PDFs convert reliably with almost any tool. Multi-table documents, merged cells, and complex layouts require more capable tools. If your documents contain handwritten text, see our guide to the best handwriting OCR software.
Budget: Free options (iLovePDF, PDF2Go, Zamzar free tier) work for occasional simple conversions. Mid-range tools (Lido, Smallpdf Pro, Nitro) suit teams with regular conversion needs. For a broader view of document processing tools, see our best PDF data extraction tools guide.
Now that you know the strengths of each PDF converter, you can choose the one that fits your document types and workflow requirements.
The best PDF converter depends on your goal. For converting PDFs to editable Word or PowerPoint documents while preserving layout, Adobe Acrobat Pro is the most accurate option. For extracting structured data from PDFs into Excel or CSV — invoice data, form fields, table values — Lido is the best choice because it understands document structure and outputs clean, labeled fields without manual cleanup. For quick, free conversions, Smallpdf and iLovePDF handle most everyday needs.
Format conversion turns a PDF into another file type while preserving how the document looks — fonts, images, layout, spacing. Data extraction pulls specific values out of a PDF and organizes them into structured rows and columns. Format converters produce editable documents. Data extractors produce usable data. Most format converters do a poor job of data extraction because they're optimizing for visual fidelity, not field identification.
Yes. PDFgear is completely free with no page limits or watermarks. Smallpdf and iLovePDF both offer free tiers with daily conversion limits. Zamzar allows free conversions for files under 50MB. For data extraction, Lido offers 50 free pages and Tabula is fully free and open source for table extraction from digital PDFs.
Yes, but you need a tool with OCR (optical character recognition). Adobe Acrobat Pro, ABBYY FineReader, and Nitro PDF all include OCR for scanned documents. Free tools like Smallpdf have basic OCR but accuracy is lower on complex layouts. For extracting structured data from scanned PDFs into spreadsheets, Lido's AI handles scanned documents including low-quality scans and phone photos.
