Make Your Video Smaller

Two ways to make a video smaller

Most of the time you do not have an exact megabyte figure in mind — you just want the file to stop being enormous without it turning to mush. That is what this tool is for. It gives you two ways to say what you want, and they are genuinely different instructions to the encoder rather than two labels for the same thing.

Quality level fixes the picture. You choose how good it should look, and the file lands wherever that footage happens to cost — a simple screen recording will shrink dramatically, while dense handheld footage will not shrink as much, because it genuinely needs the bits. This runs as a single pass, which makes it the fastest mode, and it keeps your original resolution and frame rate rather than quietly shrinking the frame.

Percentage smaller fixes the size instead. "50% smaller" means the result is at most half the original, and the picture is whatever fits in that budget. Because encoders treat a bitrate as a target rather than a promise, this mode encodes, weighs the real output, and re-encodes at a corrected setting if it came out over — so the ceiling actually holds.

You cannot have both at once, and any tool claiming otherwise is quietly picking one for you. Fixing the quality means giving up control of the size; fixing the size means giving up control of the quality. Pick whichever one you actually care about — and if you need to land under a hard platform limit like Discord's 50 MB, use the exact-size compressor, which is built around that one job.

Everything runs through WebCodecs, the browser API that exposes your device's hardware video encoder, so compression typically runs several times faster than real time. Output is MP4 with H.264 and AAC by default, which plays on every modern device. Your file never leaves the tab.
