About

Slim Video Compressor

Read full description

Slim shrinks big videos down to a size you can actually send — right on your iPhone, without uploading anything to anyone. Pick a video, tell Slim where it's going, and it works out the rest. No bitrate math, no guessing, no waiting on an upload bar. COMPRESS FOR WHERE IT'S GOING Choose a destination and Slim targets that exact limit: • Email — 25 MB • Discord — 10 MB • WhatsApp — 64 MB • iMessage — 100 MB • Custom — type any size in MB Or skip size targets and pick a quality level instead: Small, Balanced, or High. KEEP THE QUALITY THAT MATTERS • 10-bit HDR passed through, not flattened to SDR • Keep the original resolution, or cap at 1080p or 720p • HEVC for the smallest files, H.264 when you need it to play everywhere • Original frame rate preserved BATCH WITHOUT BABYSITTING Queue up as many videos as you like and let them run. Leave the app and Slim keeps going in the background, then saves everything back to your photo library. PHOTOS TOO Convert HEIC photos to JPG or PNG so they open anywhere, with a quality slider and a one-tap switch to strip location and EXIF data before you share. NOTHING LEAVES YOUR DEVICE Slim has no server, no account, and no sign-up. Compression runs on your iPhone's own video hardware. Your videos are never uploaded, never seen by us, and never sent to a third party. There are no ads, no analytics, and no trackers — none, not "anonymized".
