About FileConverter
FileConverter is a complete UK-based utility for all your file conversion needs. We specialize in everyday format changes including PDF to DOCX, HEIC to JPG, and MP4 to MP3. Whether you're a professional looking to standardize deliverables or a student submitting coursework, our free online converter provides the speed and privacy you require.
Our platform handles hundreds of conversion pairs across multiple categories. In addition to the main converter, our tools hub offers specialized utilities for image compression, video trimming, and ZIP archive management—ensuring you have the right tool for every digital task.
Step 1: Upload your files or paste a link from Google Drive or Dropbox. Step 2: Choose your desired output format from our extensive list of supported types. Step 3: Use our built-in tools to adjust quality, dimensions, or length if needed. Step 4: Click 'Convert' and download your high-quality output instantly.
Security is our priority. Many conversions run entirely within your browser using WebAssembly, meaning your data never leaves your device. For tasks that require server processing, files are handled ephemerally and deleted immediately after the job is done. We never reuse or sell your data.
Documents: PDF, DOC, DOCX, TXT, RTF, XLSX, PPTX, ODT, ODS, EPUB, and CSV. Images: JPG, PNG, WebP, GIF, TIFF, AVIF, SVG, and HEIC. Video & Audio: MP4, MOV, AVI, MKV, WebM, MP3, WAV, AAC, FLAC, and OGG. Archives: ZIP and RAR extraction. Images up to 200MB · Video/audio up to 2GB · Documents up to 200MB.
Looking for more than just a format change? Browse our tool directory for advanced archive management (ZIP/RAR), image optimization, and video editing. Each tool is designed to be lightweight, efficient, and accessible from any device.
Unlike generic converters, FileConverter focuses on transparency and user privacy. We don't require accounts, we don't watermark your files, and we provide clear information about file limits and processing methods. It's the simple, reliable choice for users who value their data and their time.
Optional team accounts are available for those who need professional features like PDF watermarking and usage analytics, but basic conversion will always remain free and accessible to everyone.
Picking the correct output format matters as much as the conversion itself. For photos headed to the web, WebP or AVIF cut file size dramatically compared with PNG, while JPG remains the safest choice for universal compatibility. For documents you want to keep editable, DOCX is ideal; for final sharing and printing, PDF locks the layout so it looks identical everywhere. Audio splits into lossless formats like FLAC and WAV for editing and archiving, and lossy formats like MP3 and AAC for everyday listening.
Our blog explains these trade-offs in plain English, with practical guides such as HEIC vs JPG, the best image format for the web, PDF to Word without losing formatting, and lossless vs lossy audio. If you are unsure which format to convert to, start there and you will make the right call in seconds.
Some conversions come up again and again. iPhone users frequently convert HEIC to JPG so photos open on Windows and older websites. Office workers convert PDF to Word to edit fixed documents, and Word to PDF to finalise them. Creators convert MOV to MP4 for wider compatibility, MKV to MP4 for phones and browsers, and extract MP3 audio from video for podcasts and playlists. Web teams convert PNG to WebP to speed up their pages.
You can jump straight to any of these from our convert directory, which lists every supported pair by category, or use the homepage converter above and pick your formats directly. Every conversion page includes step-by-step guidance, file-size limits, and answers to the most common questions.
