Smart Convert-File Convertor

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.
