Yes, FileSwift is genuinely free for everyday use with no hidden charges, no watermarks, and no credit card required. Free users can convert files up to 10MB per batch and run up to 5 conversions per day, which covers the vast majority of personal and professional use cases. If you need more: larger files, higher volume, or priority processing, FileSwift Pro costs $11 per month (or $105 per year) and gives you 100MB file size limits and unlimited daily conversions. There are no ads anywhere on the platform, and we will never sell your data or charge you unexpectedly. What you see is what you get.

Your privacy is a core part of how FileSwift is built, not an afterthought. Every file you upload is processed on secure Google Cloud infrastructure and automatically deleted within 24 hours, no exceptions. We do not read your files, we do not store them beyond the conversion window, and no human ever has access to your documents. Your files are transmitted over HTTPS at all times and processed in an isolated environment. If you are converting sensitive documents: contracts, CVs, medical records, financial statements, you can trust that FileSwift handles them with the same care you would expect from enterprise software, at no cost.

No. You can convert files immediately without creating an account or providing an email address. Just visit the dashboard, upload your file, select your output format, and download, the entire process takes seconds with zero friction. Guest users get 5 free conversions per day with files up to 10MB. If you want to save your conversion history, re-download previous outputs, or unlock higher limits, you can create a free account in under 30 seconds using your email or Google account. Signing up never triggers a paywall, the free tier remains fully functional with an account, you just get the added benefit of a conversion history.

FileSwift currently supports over 60 file conversion pairs across four categories. For documents, you can convert between PDF, Word (DOCX), Markdown, TXT, HTML, and more. For images, we support JPG, PNG, WEBP, HEIC, SVG, GIF, TIF, BMP, and PDF. For data files, we handle CSV, JSON, XML, XLSX, XLS, YAML, and PLIST conversions. We also support EPUB to PDF for ebooks. We actively add new formats based on user demand, if there is a conversion you need that is not listed, you can request it via our contact page. FileSwift is particularly strong on AI-ready formats like PDF to Markdown and PDF to JSON, which most competitor tools do not offer.

File size limits depend on your plan. Free users and guest users can convert files up to 10MB per batch, this covers the majority of standard documents, images, and spreadsheets. FileSwift Pro users get 100MB per batch, which handles large multi-page PDFs, high-resolution images, and complex spreadsheets with ease. FileSwift Business users get 500MB per batch for enterprise-scale document processing. All plans support batch conversion, you can upload multiple files at once and convert them all in a single job, with the total batch size subject to your plan limit. If you regularly work with very large files, upgrading to Pro removers that barrier entirely.

Yes, FileSwift is built for batch conversion from the ground up. You can upload multiple files in a single session and convert them all simultaneously rather than one at a time. Each file in your batch can even be converted to different output formats in the same job, for example, you can upload a mix of JPGs and PDFs and convert them all in one click. When your batch is complete, FileSwift automatically packages all your converted files into a single ZIP download so you are not clicking through individual downloads. Free users can batch convert up to 10MB total per job. Pro and Business users get significantly higher limits for processing large document collections.

The main differences come down to four things. First, no ads. ILovePDF and Smallpdf both serve advertising throughout their free tier experience. FileSwift has no ads anywhere, ever. Second, no forced signup, most competitors require you to create an account before you can do anything useful. FileSwift lets you convert immediately with no account required. Third, AI-ready formats: FileSwift offers PDF to Markdown, PDF to JSON, and Markdown to HTML conversions that are specifically designed for feeding documents into AI tools like ChatGPT, Claude, and Gemini. Very few competitors market or optimise for this use case. Fourth, modern infrastructure: FileSwift is built on Google Cloud Run with automatic scaling, meaning conversions are fast and reliable regardless of traffic levels. We are a newer, leaner product built for how people actually work in 2026.
