Convexy — File Converter

Convexy is the honest file converter. Every conversion runs entirely on your iPhone or iPad using Apple's own frameworks - your files never leave your device. No cloud uploads, no account, no tracking, and no subscription. Just a 14-day free trial, then a one-time $4.99 unlock. Yours forever. Most converters upload your private files to a server and bill you every week. Convexy does the opposite, on purpose. WHAT IT CONVERTS • Images - convert among 11 formats and to/from PDF, strip EXIF & GPS metadata, resize, and develop camera RAW. (JPG, PNG, HEIC, TIFF, BMP, GIF, ICO, SVG, RAW, AVIF, PDF) • Video - MOV ⇄ MP4 ⇄ M4V, make animated GIFs, extract the audio, grab a still frame, trim and re-encode. • Audio - convert among six formats with control over bitrate, sample rate and channels. (M4A, MP3, WAV, AIFF, CAF, FLAC) • Documents - PDF ⇄ images, PDF → text, and convert between TXT, RTF, HTML, Markdown, CSV and JSON. • Archives - compress to ZIP, TAR, GZ or BZ2, and open almost anything — including 7z and RAR — to preview and extract. BATCH & TOOLS Convert a whole album at once. Plus PDF merge and split, a QR code generator, archive tools, file checksums (MD5/SHA/CRC32) and password encryption - most of them free forever, no purchase needed.
