File Conversion Without Privacy Risk
Traditional file conversion services require you to upload your files to their servers. This means your documents, photos, and private files travel across the internet and are stored on someone else's computer.
Browser-based file conversion eliminates this risk entirely. Modern JavaScript and HTML5 APIs can convert most common file formats directly in your browser - your files never leave your device.
Which File Types Can Be Converted in the Browser?
Images (JPG, PNG, WebP, HEIC, AVIF, GIF, BMP, TIFF, SVG), audio (MP3, WAV, FLAC, AAC, OGG), and many document formats can be converted entirely in the browser using JavaScript APIs.
Some conversions (like video format conversion with codec changes, or complex document conversion) still require server processing due to computational requirements.
215+ Supported File Formats
Convert images, video, audio, documents, ebooks, archives, fonts, and presentations. All major formats are supported with conversion paths between them.
The most popular conversions: JPG to PNG, PNG to WebP, HEIC to JPG, MP4 to MP3, PDF to DOCX, EPUB to MOBI, MP3 to WAV, and hundreds more.
Why Convert Files?
Compatibility
Different devices, apps, and platforms support different file formats. Converting ensures your file opens correctly on the recipient's device.
File Size Reduction
Converting to a more efficient format (like JPG to WebP, or WAV to MP3) can dramatically reduce file size for easier sharing and storage.
Editing Requirements
Some tools only work with specific formats. Converting a PDF to DOCX lets you edit the content in Word. Converting RAW photos to JPG makes them viewable everywhere.
Platform Requirements
Social media, websites, and email services often have format requirements. Converting ensures your files meet upload specifications.

Start Converting FreeTips for Successful File Conversion
Use the Right Output Format
Choose the format that your recipient or platform needs. When in doubt: JPG for photos, PNG for graphics, MP4 for video, MP3 for audio, PDF for documents.
Keep the Original File
Always keep your original file. Lossy conversions (like JPG or MP3) reduce quality permanently. You may want to convert again with different settings.
Check File Size Requirements
Many platforms have maximum file size limits. Check requirements before converting and adjust quality settings to meet the limit.
