FileDiffs vs Draftable: Free File Comparison Compared

FileDiffs vs. Draftable: Which Document Comparison Tool Should You Use?

FileDiffs is the better fit if you want unlimited free comparisons with no file size cap and no upload to a server. Draftable is the better fit if you need legal-grade redlining, Microsoft Office integrations, or an API to build comparison into your own software. The right choice depends on three things: how sensitive your files are, what file types you compare, and whether you need enterprise features like DMS integration.

Both tools solve the same basic problem — finding what changed between two versions of a file — but they're built for different users. Here's how they actually compare, feature by feature.

FileDiffs vs. Draftable at a Glance

How FileDiffs Works

FileDiffs compares files directly inside your browser using the native File API, without uploading anything to a cloud or external server. You drag in two files, the comparison runs on your own device's hardware, and the result — additions in green, deletions in red — appears in seconds.

This local-first design means there's no upload wait, no account requirement for basic comparisons, and no file ever leaves your machine during the process. It's a meaningfully different architecture from tools that send your files to a remote server to be processed and then return the result.

FileDiffs supports more than 60 file formats split across four categories:

• Documents: PDF, DOCX, RTF, Markdown, LaTeX, AsciiDoc
• Data and spreadsheets: XLSX, CSV, JSON, XML
• Programming and web: JavaScript, Python, SQL, HTML, and dozens more languages
• Other structured formats: email files (EML), contact files (VCF), calendar files (ICS), and configuration/env files

The free plan covers unlimited side-by-side comparisons with no login. Paid tiers — Premium at $10/month and Enterprise at $15/month — add a unified single-view mode, a line-by-line analytical view with exact line numbers, and (on Enterprise) exportable audit reports for compliance or sharing.

How Draftable Works

Draftable is available in three forms: a free browser-based Online tool, a paid Desktop app, and an API for developers who want to build comparison into their own software. A fourth product, Draftable Legal, is purpose-built for law firms and adds redlining and document management system integrations.

The free Online tool requires no signup, but it comes with real constraints that aren't always obvious on Draftable's marketing pages: a 10 MB file size limit and a 300-page cap per comparison. For a short contract or memo, that's plenty. For a long technical manual, a large spreadsheet export, or a scanned PDF, you can hit the ceiling fast.

Draftable Desktop removes that cap and processes files locally rather than uploading them, but it costs $129 per year per user and currently runs on Windows only (Mac support is planned for late 2026). Draftable Legal, aimed at law firms, runs $20.75 per user per month and adds tracked-changes redlining, Outlook integration, and connections to document management systems like iManage and NetDocuments.

Privacy and Data Handling: The Core Difference

This is the single most important distinction between the two tools, and it's the one most comparison roundups skip entirely.

FileDiffs never uploads your files anywhere — comparison happens in your browser's memory and nothing is transmitted to a server, on any plan, free or paid. Draftable's free Online tool, by contrast, processes your documents on Draftable's servers; Draftable states this data is encrypted in transit and at rest, but it does leave your device. Only Draftable Desktop matches FileDiffs' fully local model, and that requires the $129/year purchase.

If you're comparing a public template or a non-sensitive draft, this distinction may not matter much. If you're comparing an unsigned NDA, a financial model, proprietary source code, or anything covered by client confidentiality, it's the deciding factor — and it's free with FileDiffs, where it costs $129/year with Draftable.

Pricing Compared

FileDiffs has three tiers, with annual billing saving roughly 16% over monthly:

• Free — $0 forever. Unlimited side-by-side comparisons, no login, all 60+ formats, full local processing.
• Premium — $10/month. Adds unified and line-by-line views plus priority support.
• Enterprise — $15/month. Adds exportable audit reports and unlimited high-volume sessions.

Draftable has four tiers across its product line:

• Online — Free, but capped at 10 MB and 300 pages per comparison.
• Desktop — $129/year per user (uncapped, local processing, Windows only).
• Business — $10.75/user/month, billed annually.
• Legal — $20.75/user/month, billed annually, includes redlining and DMS integrations.

For a quick, occasional comparison of a small file, both free tiers work. The moment you need higher volume, larger files, or guaranteed local processing without a 300-page ceiling, FileDiffs stays free where Draftable requires a paid plan.

Which One Should You Use?

Choose FileDiffs if:

• You want to compare files without uploading them anywhere, on the free plan
• You work with file types outside the standard Word/PDF/Excel set — code, JSON, Markdown, config files
• You compare files occasionally and don't want to pay anything
• File size is unpredictable and you don't want to run into a server-side cap

Choose Draftable if:

• You're on a legal team that needs redlining, tracked changes, and DMS integration
• You need Outlook or Microsoft Word add-ins built directly into your existing workflow
• You're comparing scanned PDFs that require OCR
• You need an API to embed comparison functionality inside your own product

Common Mistakes When Comparing Documents Online

Assuming "free" means unlimited. Draftable's free Online tool caps out at 10 MB and 300 pages — a limit that isn't prominent on the product's main marketing pages. Check the fine print before you start a comparison on a large file.

Uploading sensitive files without checking where processing happens. Not every "compare documents online" tool processes files the same way. Some upload to a server; others, like FileDiffs, never do. If your files are confidential, this matters more than any feature list.

Ignoring file format support until mid-task. A tool built for Word and PDF won't necessarily handle a JSON config file or a LaTeX document well. Confirm format support before you commit to a workflow.

Comparing scanned PDFs without OCR. A scanned PDF has no underlying text layer unless it's been through OCR first. Tools that compare the visual layout alone may miss content changes entirely.

Best Practices for Choosing a Document Comparison Tool

• Match the tool to the file type you compare most often — a tool optimized for legal redlining isn't necessarily the best choice for comparing spreadsheets or code.
• Check the file size and page limits on any free tier before relying on it for anything beyond a quick, casual check.
• Confirm how the tool handles your data — local processing versus server upload — especially for anything confidential.
• Test with a real file from your own workflow, not just the tool's demo document, before deciding which one to adopt.

Conclusion

FileDiffs and Draftable both solve the same core task, but they're optimized for different priorities. FileDiffs wins on privacy architecture, free-tier limits, and format breadth — all without ever uploading a file. Draftable wins on legal-specific features, Office integrations, and enterprise document workflows, at a price.

If you're comparing files occasionally and care about keeping them off a server, try FileDiffs free — no signup, unlimited side by side commparison, no file size cap.
