Open the Bulk Image Compressor tool, add up to 30 images, set your options below, press Convert All and download — the whole job runs on your device, so it is free, private and takes seconds.
Step by step
Load the Bulk Image Compressor page. Nothing installs and nothing signs in — the editor appears immediately, ready for files.
Drag files onto the drop zone, click to browse, or paste from the clipboard. You can load up to 30 at once for a batch job.
Drag the quality slider, or type an exact KB target. Start around 80% for photos and lower only if you must hit a strict budget.
Press Convert All. Because everything runs on your device, a whole queue of photos finishes in a few seconds.
Save each result individually, or grab the entire batch as a single ZIP. Files keep their original resolution unless you set a cap.
Settings that matter
| Quality | Lower = smaller file, higher = more detail. ~80% is a good web default. |
|---|---|
| Output format | WebP — consider WebP/AVIF for the smallest web images. |
| Max pixels | Optional downscale if size must drop fast. |
Pro tips & common mistakes
- For the web, prefer converting to WebP/AVIF then compressing — modern formats start smaller.
- Resolution is preserved by default; only lower the pixel cap if the destination truly needs it.
- Batch it: up to 30 files per run beats doing them one at a time.
- Keep originals for anything critical — the tool never touches the source file, but always keep your master copy.
