Images, video, audio, documents and archives — converted entirely on your device. No cloud, no tracking, no fine print.
Pick a file — we'll show the formats it can become.
Pick from Files or Photos, or share straight into Convexy from any app. Choose several at once to batch them.
We only ever offer the formats your file can actually become. Tweak quality, size, codec — or don't.
See exactly what you got — including how much smaller — then save to Photos, Files, or share it on.
Convert among 11 formats including WebP and ICO, to and from PDF, trace to SVG, strip EXIF/GPS, resize, and develop camera RAW.
MOV ⇄ MP4 ⇄ M4V, make animated GIFs, pull the audio out as MP3, M4A, WAV or FLAC, and grab a still frame.
Convert among six formats — including to MP3, which iOS itself cannot do — with control over bitrate, sample rate and channels.
PDF ⇄ images, PDF → text, and convert between TXT, RTF, HTML, Markdown, CSV and JSON.
Compress to ZIP, TAR, GZ or BZ2 — or open almost anything, including 7z and RAR, to preview and extract.
Convert a whole album at once. Plus PDF merge/split, a QR generator, archive tools, file checksums and password encryption — most of them free forever, no purchase needed.
Every conversion runs on your device — on the operating system's own frameworks, plus a few bundled open-source encoders for the formats Apple leaves out.
PDF merge & split, the QR generator, archive compress/extract, file checksums and opening encrypted files never need a purchase — even after the trial ends. Only creating encrypted files is part of the one-time unlock. Generosity, in writing.
Convexy has no backend, no accounts, and no analytics. Your photos, documents and recordings are converted on your phone and stay there. It works on a plane, in a tunnel, anywhere — because it never needed the internet to begin with.
