Downsize shrinks your videos and photos to fit any size limit — email attachments, WhatsApp, Discord, upload forms — without killing the quality. Set a target like 25 MB and Downsize does the math for you: it picks the right bitrate, compresses, then checks the real file size and automatically tries again if it's still too big. You get a file under your limit. Every time. Everything runs 100% on your iPhone. Your videos and photos never leave your device — no uploads, no cloud, no account, no waiting on a server. COMPRESS TO AN EXACT SIZE • Pick a target: 10 MB, 25 MB, 50 MB, or your own custom limit • Guaranteed under your target — we measure the output and re-compress if needed • See the estimated size before you start BUILT FOR QUALITY • Modern HEVC (H.265) encoding — same quality at a smaller size • H.264 option for maximum compatibility • Choose resolution, bitrate and frame rate yourself in Expert mode • Proper HDR & Dolby Vision handling — tone-mapped to SDR so your video never comes out washed out PHOTOS TOO • Compress photos to HEIC or JPEG • Control quality and target size • Smart downscaling keeps images sharp BATCH CLEANUP • Select many videos at once and compress them in one queue • Review before and after side by side • Free up storage: keep the smaller copy and remove the original — only when you confirm YOUR ORIGINALS ARE SAFE • Downsize always creates a copy first • Nothing is deleted or overwritten unless you explicitly say so WHY DOWNSIZE • Private by design — fully offline, nothing uploaded • No subscription — pay once, keep it forever • Fast native compression using Apple's own video engine • Clean, simple interface Download Downsize and stop fighting with "file too large" errors. — Free: unlimited single-file compression, preset target sizes (10/25/50 MB).

Verdict
The clearest difference is in-app purchases: Lydsto at none against Downsize's 1. Lydsto also leads on iOS requirement (13.0 vs 16.0). On price, ads and device support there is nothing between them.
