Video compression trades encoded detail and bitrate against output size. MimiFile provides practical quality presets so you can create a lighter copy for upload, sharing or storage while keeping the original video unchanged. The amount saved depends on the source codec, resolution, motion, duration and existing compression.
Favor visual quality when preserving more detail matters more than obtaining the smallest possible output.
Use a middle preset for general sharing when both file size and visible quality matter.
Choose stronger compression when reducing transfer or storage size is the priority, while expecting a greater chance of visible quality loss.
Not always. A video that is already efficiently compressed may have less room to shrink than a high-bitrate or lightly compressed source.
Lossy video compression can reduce encoded detail. Stronger compression generally increases the risk of visible artifacts, especially in complex motion or textured scenes.
No. Compression produces a separate result so the source file remains available unchanged.
