Upload your MP4 file to Convertio, select AVI as the output format, choose your preferred quality settings, and click convert. Our advanced compression algorithms maintain video quality while ensuring compatibility with older media players and editing software that require AVI format.
Yes! Convertio supports batch file conversion, allowing you to upload and convert dozens of files at once. Simply select multiple files, choose your desired output format, and our system will process them simultaneously, saving you time and effort when dealing with large file collections.
No, Convertio doesn't impose file size limits. Whether you're converting small social media videos or large 4K recordings, our WebAssembly-powered conversion engine handles files of any size efficiently. The conversion speed depends on your device's processing power and the complexity of the conversion.
Lossless formats like FLAC preserve all original audio data, while lossy formats like MP3 compress files by removing some audio information. When converting FLAC to MP3, you trade file size for audio quality. Our converter lets you choose bitrate settings to balance quality and file size according to your needs.
When converting PNG to JPG, transparent areas are automatically filled with white background since JPG doesn't support transparency. For best results, consider using PNG format when transparency is needed, or manually add a background color before conversion to JPG format.
Yes, Convertio can convert PDF files to DOCX format, making them editable in Microsoft Word. The conversion preserves text formatting, images, and basic layout structure. For complex PDFs with intricate layouts, some manual formatting adjustments might be needed after conversion.

Your files never leave your device or get uploaded to external servers, ensuring complete privacy and security. This makes it safe for converting sensitive documents, personal photos, and confidential business files.
MP4 format with H.264 codec is universally supported across all social media platforms including YouTube, Instagram, TikTok, and Facebook. For optimal results, convert your videos to MP4 format with appropriate resolution settings: 1080p for general use, 720p for faster uploads, or 4K for high-quality content.
For web optimization, convert images to WEBP format for modern browsers (smaller file sizes with better quality) or JPG format for universal compatibility. Use quality settings between 80-90% to balance file size and visual quality. PNG format is best for images with text, logos, or transparency requirements.
Absolutely! Upload your video file (MP4, AVI, MOV, etc.) and select an audio format (MP3, WAV, FLAC) as output. Convertio will extract the audio track while maintaining the original quality. This is perfect for creating podcasts from video recordings or extracting music from music videos.
