Smart Convert-File Convertor Live

The all-in-one file converter, video compressor, image resizer, audio extractor and PDF scanner — 100% offline, 100% private. Your files never leave your phone. Smart Convert is the universal Android file converter you actually need. Convert MP4 to MP3, WEBM to MP4, PDF to JPG, HEIC to JPG, PNG to WEBP, WAV to MP3, JSON to CSV, and 300+ more format combinations. Everything happens locally on your device — no uploads, no accounts, no tracking. ★ SMART CONVERT — pick where you'll use the file (WhatsApp, Email, Website, Upload, Max Quality) and ConvertX picks the right format, resolution, quality and bitrate automatically. ★ MAKE IT FIT — type a target size (e.g. 10 MB) and ConvertX auto-shrinks quality, resolution and bitrate until the file fits under your limit. Perfect for email attachments, WhatsApp video sharing, or upload limits. ★ VIDEO COMPRESSOR — shrink large MP4, MOV, MKV, AVI, WEBM videos without losing quality. Ideal for messaging apps, storage cleanup, or sending clips via email. ★ AUDIO EXTRACTOR — pull the audio track out of any video and save it as MP3, M4A, WAV or OGG. Convert YouTube-style videos you already have on your phone into music files. ★ PHOTO / VIDEO → GIF — turn a short clip or a set of photos into an animated GIF ready to share on chat, forums or Reddit. ★ PDF SCANNER — take photos of documents, contracts, receipts or book pages, and ConvertX merges them into one clean PDF document. Works fully offline. ★ BATCH CONVERTER — pick 10, 50, 100 images at once, choose the target format (JPG, PNG, WebP, PDF) and download them all in a single ZIP archive. ★ QR BATCH SCANNER — scan dozens of QR codes at once and export results to CSV. Ideal for tickets, inventories, coupon codes or bulk data collection. ★ FILE CLEANER — find duplicate files by SHA-256 hash to free up storage. Detects identical images, videos, audio or documents regardless of filename. ★ SHARE INSTANTLY — after every conversion, share directly to WhatsApp, Email, Gmail, Drive, Telegram, Photos, Bluetooth or any Android app with one tap.
