When a whole folder is too big — footage to archive, clips to attach, a set of recordings that must each fit a size cap — this queue compresses every file with the same quality or size target. Add the videos, set the target once, and each compressed file downloads as it finishes, without anything leaving your device.

A shared quality target vs. a shared size cap

These behave very differently across a mixed set. A shared quality target gives every file consistent visual quality and lets each land at whatever size it needs, so a 10-second clip stays small and a 10-minute one stays large. A shared size cap forces every file into the same budget, which means the short clips come out looking excellent and the long ones come out starved. Use a quality target for archiving and general shrinking, and a size cap only when each individual file must clear a hard limit.

Estimating time and checking results

Compression time scales with total duration and resolution rather than with file count, so ten one-minute clips take about as long as one ten-minute video. Before committing to a long queue, compress one representative file on its own and look at it: settings that seem reasonable on a spreadsheet can be visibly wrong on your actual footage, and finding out after forty files is expensive. Once the sample looks right, run the batch with confidence.

Questions, answered

Can I set a size limit for every file?

Yes, but be careful with mixed sets: a shared cap gives short clips excellent quality and long ones very little. A shared quality target is usually the better choice unless each file must clear a hard limit.

How long will a batch take?

Roughly proportional to the total duration and resolution of all the files, not the number of them. Ten one-minute clips take about as long as one ten-minute video.

Will all my files be the same quality?

With a quality target, yes — that is the point. With a size cap, no: quality varies with each file’s length, since the same budget stretches further over a shorter clip.

Should I test before running a large batch?

Yes. Compress one representative file first and look at the result. Verifying the setting on a single clip is far cheaper than discovering a problem after forty.

Are my videos uploaded to compress them?

No. Every file is processed inside the browser tab, so nothing is sent to a server and the queue works on private material.
