Why Browser-Based Tools?
Most online tools upload your files to remote servers. That means slower processing, privacy concerns, and daily usage limits. Browser-based tools process everything locally on your device - your files never leave your machine.
Here are 10 tools that run 100% in your browser and are completely free.
1. Image Compress
Reduce image file sizes by up to 80% without visible quality loss. Uses MozJPEG and OxiPNG compression engines running in WebAssembly.

How to use: Drop your JPG, PNG, or WebP image, adjust the quality slider (80% is a good starting point), and download the compressed file.
Try it: Image Compress
2. AI Background Remover
Remove backgrounds from photos using an AI model (MODNet) running in your browser. Full original resolution, no watermark, no daily limit.

Unlike remove.bg which caps free output at 500x500 pixels, this gives you the full resolution for free. The trade-off: edge quality on very fine hair isn't quite as sharp.
Try it: Background Remover
3. Invoice Generator
Create professional PDF invoices without signing up for an accounting platform. Fill in the form, see a live preview, and download the PDF.

Supports 14 currencies with proper number formatting, tax calculation, and discount fields. Your financial data stays on your device.

4. Video Compressor
Compress video files using FFmpeg compiled to WebAssembly. Reduce MP4 file sizes by up to 90% without re-uploading to any server.

Processing is slower than server-based tools (WASM vs native), but your videos stay completely private. No watermarks on output.
Try it: Video Compressor
5. JSON Formatter
Format, minify, and validate JSON with syntax highlighting and error detection. Essential for any developer working with APIs.

Paste messy JSON, click format, and get clean indented output. Errors are highlighted with line numbers.
Try it: JSON Formatter
6. PDF Merge
Combine multiple PDF files into a single document. Drag to reorder pages before merging.

Uses pdf-lib (MIT licensed) to process documents entirely in your browser. No file size limits beyond your device's RAM.

7. QR Code Generator
Create QR codes for URLs, text, Wi-Fi credentials, and more. Customize colors and download as PNG.

8. CSS Box Shadow Generator
Build layered box shadows visually with live preview. Copy the CSS with one click.

Add multiple shadow layers, adjust blur, spread, color, and position. Great for designers who want to fine-tune shadows without writing CSS by hand.

9. PDF Split & Compress
Extract specific pages from a PDF or compress PDF files for email attachments. Both tools process locally.
- PDF Split - extract page ranges
- PDF Compressor - reduce file size
10. Screen Recorder
Record your screen, window, or browser tab with audio. Download as WebM. No install needed.
Great for bug reports, tutorials, or quick demos. Uses the browser's native Screen Capture API.
