All processing happens locally in your browser âĸ Lightning fast âĸ 100% private âĸ Batch & ZIP support
Files never leave your device. All processing runs inside your browser using JavaScript & WebAssembly â zero server uploads.
No upload queues or server wait times. Conversion starts the instant you drop a file â results ready in seconds, not minutes.
No daily limits, no watermarks, no forced sign-ups. Convert as many files as you need, forever. Batch processing & ZIP download included.
Built on proven open-source libraries like pdf.js, sharp, and libvips. Transparent algorithms you can inspect in your browser DevTools.
No sign-ups. No installations. No file uploads to unknown servers. Here's exactly what happens when you use any tool:
Drag & drop one or many files onto the tool interface â or click to browse. Supported formats are clearly labeled on every tool page.
Your browser's JavaScript engine (and WebAssembly where available) processes the file instantly. The file never leaves your device â you can verify this in your browser's Network tab.
One-click download for single files, or automatic ZIP bundling for batch conversions. Files are generated as Blob URLs in your browser memory.
Convert, merge, split, compress, secure, and annotate PDF documents â entirely inside your browser. Our PDF engine uses Mozilla's pdf.js library for rendering and jsPDF for generation, ensuring pixel-perfect output without any server dependency. Whether you're a student combining assignment pages, an accountant extracting invoice tables to Excel, or a legal professional archiving contracts to PDF/A â these tools handle it with zero data exposure.

We believe trust is earned through transparency. Here's exactly what technology runs under the hood when you use our converters.
Every tool runs entirely inside your browser tab. We use the HTML5 File API and Canvas API for image processing, WebAssembly compiled codecs for advanced format support (HEIC, AVIF, TIFF), and Web Workers for multi-threaded batch operations that don't freeze your browser.
PDF rendering uses Mozilla's open-source pdf.js (v4.x) â the same engine powering Firefox's built-in PDF viewer. PDF creation uses jsPDF and pdf-lib for merge, split, rotate, encrypt/decrypt, page numbering, and watermark operations. All processing happens in a sandboxed JavaScript context.
Our tools make zero outbound HTTP requests with your file data. You can verify this yourself: open DevTools â Network tab before converting a file. You will see no upload requests. Files are read locally via FileReader and output as Blob URLs.
Background removal and image upscaling use lightweight TensorFlow.js and ONNX Runtime Web models loaded directly into your browser. The AI model weights (~5â15 MB) are cached locally after first use. No cloud inference, no API calls, no data shared with any third party.
Our converters serve professionals across every industry â here's how different users rely on them daily.
Merge scanned notes into a single PDF, convert assignment screenshots to Word, or compress large presentation files to meet submission limits â all without creating an account.
Extract invoice tables from PDF to Excel, lock contracts with passwords, convert proposals to PDF/A for archival compliance, and add page numbers for professional documents.
Batch-convert HEIC photos from iPhone shoots, export PSD mockups to JPG for client review, generate WebP assets for web performance, and remove backgrounds from product photos using AI.
Compress images to pass Core Web Vitals, convert SVG icons to PNG fallbacks, resize social media assets to exact platform dimensions, and generate optimized WebP files for faster page loads.
Everything you need to know about our free browser-based conversion tools.
Yes â completely free, with no daily conversion limits, no watermarks on output files, no forced account creation, and no premium upsells. All 42 tools are fully functional from day one. We sustain development through non-intrusive display advertising.
No â your files never leave your device. Every conversion runs entirely inside your web browser using JavaScript and WebAssembly. We have zero server-side file processing infrastructure. You can verify this by opening your browser's Developer Tools (F12) â Network tab before using any tool â you'll see no file upload requests.
Since processing happens in your browser, the limit depends on your device's available RAM rather than server restrictions. Most modern devices handle files up to 500 MB without issues. For very large files (1 GB+), we recommend closing other browser tabs to free up memory. Batch operations create output files as a ZIP archive for convenience.
All tools work in any modern browser that supports ES6+ JavaScript and the HTML5 Canvas API, including: Chrome 90+, Firefox 90+, Safari 15+, Edge 90+, and Opera 80+. They work on desktop (Windows, macOS, Linux) and mobile (iOS Safari, Android Chrome). For best performance on large batch jobs, we recommend a desktop browser with at least 4 GB RAM.
Most online HEIC converters upload your photos to a server for processing â meaning your personal images pass through third-party infrastructure. Our HEIC to JPG tool uses a WebAssembly-compiled libheif decoder that runs entirely in your browser. Your iPhone photos are decoded locally, converted to JPG via the Canvas API, and downloaded directly â zero cloud exposure.
Our background removal tool uses a pre-trained U2-Net segmentation model compiled for TensorFlow.js. The model weights (~7 MB) are downloaded and cached in your browser on first use. After that, it works fully offline. The AI identifies foreground subjects through semantic segmentation and generates a clean alpha-channel mask â all computed on your device's CPU/GPU via WebGL.
Absolutely. There are no restrictions on how you use the converted output files. Whether you're processing client deliverables, preparing print-ready documents, optimizing product images for your e-commerce store, or creating marketing materials â all output files belong to you with no attribution required.
Three key differences: (1) Privacy â your PDFs stay on your device, unlike cloud services that temporarily store your files on their servers. (2) No account needed â no email, no credit card, no trial limits. (3) Instant processing â no upload/download wait times since everything runs locally. The trade-off is that some advanced features (like OCR on scanned PDFs) may be less accurate than server-side solutions with more processing power.
Free Image Editor Online was created by a team of web developers and privacy advocates who were frustrated with existing file conversion services that silently upload your personal documents and photos to unknown servers. We built a suite of tools that proves powerful file conversion doesn't require sacrificing your privacy.
Every tool we ship follows three principles:
