Bulk Image Compressor

Select up to 100 photos, pick a quality level, and compress them all in one go. Everything runs in your browser. Download the results as a single ZIP file.

Why Use a Bulk Image Compressor?

Photographers and content creators often deal with hundreds of images after a single session. Compressing them one by one is tedious and slow. A bulk compressor lets you select an entire folder of photos, set the quality once, and process everything in seconds.

This tool runs entirely in your browser. None of your images are uploaded to any server, so your files stay private and the compression is nearly instant. The quality slider gives you full control over the balance between file size and visual fidelity across all images at once.

Whether you need to shrink a wedding gallery for client delivery, optimize product photos for an online store, or prepare a batch of images for email, this tool handles JPG, PNG, and WebP files with a single click.

One Click, One ZIP, Done

After compression, every processed image is packaged into a single ZIP file that you can download with one click. No more renaming files or dragging them into folders manually. The ZIP preserves original file names so you can find everything right where you expect it.

The quality presets (Small, Medium, Good, Best) cover the most common scenarios, but you can also drag the slider to any position for precise control. The total size saved is displayed so you know exactly how much storage you recovered.

No accounts, no email gates, no daily limits. Open the page, drop your images, adjust quality, and download the ZIP. The entire workflow for 100 images takes under a minute on a modern device.

Frequently Asked Questions

How many images can I compress at once?

You can select up to 100 images per batch. There is no file size limit per image, though very large files may take longer to process on older devices.

Are my images uploaded to a server?

No. All compression happens locally in your browser. Your images never leave your device, making this tool completely private and safe for sensitive content like client photos.

What format is the compressed output?

The compressed files are saved as JPEG, which provides the best balance of size and quality for photographic content. The ZIP archive preserves the original file names with a .jpg extension.

Can I adjust quality differently for each image?

The quality setting applies to all images in the batch. If you need different quality levels for different images, process them in separate batches with different slider positions.

How much space will I save?

Typical savings range from 40% to 80% depending on the originals and the quality level you choose. The tool displays the total original size, compressed size, and percentage saved after processing.

Does bulk compression reduce image resolution?

No. Compression only affects file size by adjusting encoding quality. The pixel dimensions (width and height) of every image remain unchanged.
