One setting applied to every file · compressed on your device, nothing uploaded

Quick Tool Overview

The Bulk Image Compressor applies one setting to a whole folder and returns everything as a single ZIP. Per-file results are listed so an image that came out larger than it went in is visible rather than buried, and the total saved across the batch is reported. Nothing is uploaded, so client work under an NDA is fine.

About the Bulk Image Compressor

A folder of product photographs or a directory of site assets is the case where compression stops being a judgement call and becomes a chore — the same decision repeated forty times.

Set one rule and every file follows it: a quality level, an optional maximum dimension, and a target format. The per-file results are listed so an image that came out worse than it went in is visible rather than buried, and the total saved across the batch is reported. Everything runs locally, so there is no upload wait, no per-file cap and no reason to think twice about client work.

Key features of the Bulk Image Compressor

One setting, whole folder

Quality, an optional dimension cap and a target format, applied to every file in the queue.

Per-file before and after

Each row shows what happened, so a file that grew is obvious instead of hidden in an average.

Convert while compressing

Pushing the batch to WebP usually saves far more than quality alone ever will.

One ZIP back

The archive is built in the browser, so there is no downloading forty files one at a time.

Original names kept

Filenames survive into the archive, with only the extension changing if you converted the format.

There is no fixed limit — your device memory is the constraint. A hundred photographs is comfortable on a normal laptop.
