Free File & PDF Tools Online
Free, browser-based file tools for compressing images, reducing PDF sizes, converting images to PDF, and merging multiple PDF documents — all processing happens locally in your browser with no file uploads to any server. Your files stay completely private and are never stored anywhere.
File Tools That Respect Your Privacy
Most online file tools upload your files to a server for processing, creating privacy risks especially with sensitive documents. Our tools work entirely differently — all image compression, PDF processing, and file conversion happens in your browser using JavaScript. Your files never leave your device. This makes these tools safe for compressing sensitive documents, contract PDFs, and confidential images.

Frequently Asked Questions
Everything you need to know about these tools
Yes — all processing happens entirely in your browser. No files are uploaded to any server. The image compressor, PDF compressor, and PDF converter all use JavaScript running locally on your device. Your files never leave your computer, making these tools safe for sensitive documents, contracts, and confidential images.
For JPEG images, quality levels of 75-85% typically reduce file size by 50-70% with minimal visible quality loss. For PNG images, lossless compression can reduce size by 20-30%. WebP format achieves better compression than JPEG at equivalent quality. Our image compressor shows before/after comparison so you can judge the quality impact yourself before downloading.
Since all processing happens in your browser, the limit depends on your device's available memory. Most modern devices handle images up to 20MB and PDFs up to 50MB comfortably. Very large files (100MB+) may be slow on older devices. For best performance, process one file at a time for large files.
Yes — the PDF merger supports combining multiple PDF files into one. Upload all your PDFs, arrange them in the desired order, and merge them into a single document. There is no hard limit on the number of files, though very large merges may be slower on older devices.
