All the tools you need, right in your browser
Explore 172 fast, free, and secure tools. Everything runs locally on your device, meaning zero server uploads and complete privacy for your files.
Why our tools run directly in your browser without server uploads
Why our tools run directly in your browser without server uploads
Most online file converters quietly upload your confidential files to their remote cloud servers, run scripts in a distant data center, and leave copies on their drives. We took a fundamentally different engineering path: wikawe runs WebAssembly (Wasm) and native client-side engines directly inside your browser tab. Your computer or mobile phone’s processor does all the work, which means your contracts, financial spreadsheets, patient records, and family photos never leave your device.
Because your files never travel across the internet, there are zero bandwidth bottlenecks, no file queue delays, and no risk of data breaches or leaks. You can merge multi-gigabyte PDFs, compress scanned invoices, format complex JSON trees, convert photos to WebP, or stamp digital signatures in seconds—even when you are on an unstable mobile connection or working completely offline.
Whether you are handling routine daily tasks like converting Word to PDF, running OCR on receipts, calculating GST, or inspecting code with our developer toolkit, every tool is completely free with no subscriptions, paywalls, or forced email signups. Simply pick your tool, drag in your files, and download your finished result with complete peace of mind.

Common Questions About Browser Processing & Security
Everything you need to know about how our zero-upload tools keep your files private and secure.
How do these tools process files without uploading them to a server?
We run WebAssembly (Wasm) and native JavaScript engines directly inside your browser tab. When you drag and drop a PDF, image, or raw data file into any tool, your device’s own CPU and memory handle all parsing, compression, and rendering locally. Zero bytes of your file contents travel over the internet, and nothing is ever cached on an external server.
Are my confidential documents, contracts, and financial PDFs safe here?
Yes, 100%. Because your files never leave your personal computer or phone, sensitive data like signed agreements, bank statements, personal identification, and medical records remain under your control at all times. There is no remote cloud bucket where your documents could leak or be inspected by third parties.
Do I need to pay, subscribe, or create an account to use these tools?
No. Every single utility in our directory—from PDF editing, merging, and splitting to image conversion, JSON formatting, and developer helpers—is open and completely free. You can use them immediately without entering an email address or signing up for a trial.
Is there a file size limit or daily quota?
Because our servers do not host or ingest your files, we never throttle your usage with daily limits or artificial megabyte caps. The only practical limit is your device’s available RAM. You can comfortably merge, compress, or reorganize PDFs with hundreds of pages or large image batches right in your browser.
How does client-side PDF compression work without losing readability?
Our compressor inspects your PDF’s internal structure, stripping duplicate font definitions, unused metadata, redundant color profiles, and thumbnail streams. It also resamples embedded bitmap photos to standard web resolutions (like 150 DPI) while keeping text layers vector-crisp and perfectly legible for reading and printing.
Can I use these tools completely offline without an internet connection?
Yes. Once the page is loaded into your browser’s cache, all core WebAssembly libraries stay ready on your device. You can turn on Airplane mode, disconnect from Wi-Fi, and continue merging, rotating, watermarking, or editing documents with complete peace of mind.
Do you stamp watermarks or branding on my exported documents?
Never. We do not inject watermarks, promotional stamps, headers, or metadata into your exported files. The documents you export are clean, pristine, and ready for official or corporate presentation.
How does the P2P file share tool send gigabytes of data without cloud storage?
It creates a direct peer-to-peer WebRTC data channel between your browser and the recipient’s browser. The file is streamed straight from your hard drive to theirs with end-to-end encryption (AES-256-GCM) and verified with SHA-256 checksums. No cloud intermediary ever stores a single chunk of your transfer.
Does this comply with workplace privacy policies, GDPR, and HIPAA?
Yes. Because no personal data or protected health information (PHI) is transmitted or stored on any server, wikawe acts as a strictly local utility on your workstation—similar to running a native desktop application. This makes it safe for enterprise teams subject to strict compliance rules.
Can I convert scanned PDFs into editable text with OCR?
Yes! Our OCR tool analyzes scanned images and non-selectable PDF pages using browser-based machine learning (Tesseract.js). It detects letterforms, builds searchable text overlays, and lets you extract plain text or export a searchable PDF right from your device.
How accurate is the PDF to Word and Excel conversion?
Our conversion engines reconstruct paragraphs, font weights, tabular structures, and embedded illustrations from the original PDF layout. Standard digital documents convert with high fidelity into clean .docx or .xlsx spreadsheets that you can open and edit in Microsoft Office or Google Docs.
Will these tools work on my smartphone or tablet?
Yes! All tools are fully responsive and optimized for mobile touchscreens on iPhone (iOS Safari), iPad, and Android (Chrome, Firefox, Brave). You can snap photos of paper documents, merge them into PDFs, sign them with your finger, and download the finished file directly to your device storage.
