iPhone

Compress a video to fit an email, or turn HEIC into JPG — on your iPhone, with nothing uploaded anywhere. Convert and compress video and photos on your iPhone. Everything runs on the device, so your files are never uploaded — it works in airplane mode. WHAT IT DOES • Convert video — MOV/HEVC to MP4/H.264, for Windows PCs and older devices that won't play iPhone video • Compress video — get under a limit, like 25 MB for an email attachment • Convert photos — HEIC to JPG, PNG, PDF and more • Compress photos — meet an upload size limit without hunting for the right quality setting TARGET A SIZE, NOT A QUALITY SLIDER Tell it "1 MB" and it works out the settings for you. No guessing at bitrates, no converting three times to land under a limit. BUILT FOR BATCHES Pick dozens of files at once. The progress screen shows which ones are done, and you can cancel mid-run without losing what already finished. NO SERVER, NO ACCOUNT No sign-up, no watermark, no ads. The conversion engine has no networking code at all — your videos and photos never leave your iPhone. HISTORY THAT SAYS WHAT CHANGED Every job records what it actually did: HEIC → JPEG, or 248 MB → 24 MB. Not just "done". SHARE SHEET Send files straight from Photos, Files, or a messaging app. FREE AND PAID Three conversions a day are free. Remove the limit with an optional upgrade — either a yearly subscription or a one-time purchase. — The yearly plan is an auto-renewing subscription. Payment is charged to your Apple Account at confirmation of purchase. It renews automatically unless turned off at least 24 hours before the end of the current period; your account is charged for renewal within 24 hours prior to the end of the current period. You can manage or cancel it in your Apple Account settings after purchase.
