We run WebAssembly (Wasm) and modern JavaScript engines directly inside your web browser. When you drop a PDF, image, or text file into a tool, your computer or phone’s own CPU and memory do 100% of the work. Your files never get sent over the internet or saved to remote databases.

Are my confidential documents, contracts, and financial PDFs safe here?

Yes. Because the processing architecture is strictly client-side, sensitive information like tax returns, medical files, legal agreements, and corporate spreadsheets never leave your device. There is no cloud storage or server-side logging where third parties could access your data.

Do I have to pay or create an account to use these tools?

No. All core browser utilities — including PDF merge, compression, splitting, editing, signing, image conversion, and developer formatters — are free to use immediately with no sign-up or credit card required.

What is the maximum file size I can process in my browser?

There are no arbitrary server bandwidth limits or file count quotas. The practical limit is simply your device’s available RAM memory. On modern laptops and phones, you can easily process multi-gigabyte files or 1,000+ page PDF documents without hitting server timeouts.

How does the P2P File Sharing tool work without cloud storage?

The P2P file share tool establishes an encrypted WebRTC peer-to-peer data tunnel directly between your browser and the recipient’s browser. Files are compressed in real time using native Gzip, encrypted end-to-end with AES-256-GCM, and checked with SHA-256 checksums — bypassing cloud intermediaries entirely.

Can I use these tools while offline or with unstable internet?

Yes. Once a tool’s page is cached in your web browser, the underlying WebAssembly and script engines operate independently of your network. You can disconnect from Wi-Fi or turn on Airplane mode and continue editing, converting, compressing, and managing files locally.

Do your PDF or image tools add watermarks to exported files?

No. We never insert promotional watermarks, brand logos, or hidden metadata onto your downloaded PDFs, images, or converted documents. Your output files remain clean and professional.

Which web browsers and operating systems are supported?

All modern browsers that support standard WebAssembly and HTML5 APIs work seamlessly — including Google Chrome, Apple Safari, Mozilla Firefox, Microsoft Edge, Opera, and Brave on Windows, macOS, Linux, iOS, Android, and ChromeOS.

Why wikawe tools run in your browser

wikawe is a catalog of free utilities for documents, images, data, color, and everyday calculations. Each tool opens a focused workflow so you can compress a PDF, format JSON, crop a photo, or convert units without installing desktop software.

Core processing is designed to stay in your browser whenever possible. That means personal contracts, photos, and business data are not uploaded to wikawe servers just to finish a quick task. Use the search box or category filters above to jump straight to the tool you need, then follow the on-page steps to download or copy your result.

Popular PDF jobs include merge, split, compress, sign, watermark, and page management. Developers often use Smart Editor, JSON formatters, encoders, and diff checker. Designers use Smart Image, Smart Palette, and Wikawe Design for cards and posters. Every landing page includes unique guidance, FAQs, and related tools so you can chain jobs privately.
