Cinder - compress videos

Cinder compresses videos directly on your iPhone or iPad. Choose a quick preset or fine-tune every detail, then process one video or a whole batch. COMPRESS FROM ANYWHERE Send a video to Cinder from the Share Sheet, or add videos from Photos and Files. CHOOSE THE RIGHT BALANCE Start with Small or Balanced, or customize codec, resolution, bitrate, audio, frame rate, and keyframe interval. RUN THE WHOLE BATCH Queue several videos and let Cinder work through them one by one. SEE THE DIFFERENCE Compare file size, resolution, frame rate, bitrate, and duration before and after compression. SAVE IT YOUR WAY Export finished videos to Photos, share them with another app, or keep them as files in your Cinder folder in iCloud Drive. BUILT FOR PRIVACY Compression happens on your device. Your videos are not sent to Cinder servers for processing. No account required. Cinder is made for iPhone and iPad, but it also works on Apple Silicon Macs (those that powered by M-series chips).
