Honest batch image compressor

Compress Images Online

Choose a quality preset or a precise quality level. The result panel reports the actual encoded size—including when a “compressed” file grows.

How it works

From source files to finished batch

Add JPEG, PNG, or WebP

Choose the output format. JPEG and WebP use a quality setting; PNG uses its own lossless or reduced-palette encoder.

Choose quality and dimensions

Start with Balanced, or set a quality level. Optionally limit the maximum long edge for an additional size reduction.

Check the real saving

After encoding, compare the exact source and output sizes. Keep-smaller mode preserves the original if encoding grows it.

This sample uses the same image processing as the studio. Switch tools to compare real output.

Common uses

Built for everyday image work

Faster web pages

Reduce camera-sized assets before upload to lower transfer weight and improve loading behavior.

Email attachments

Shrink multiple photos to a more practical total size without installing another application.

Review copies

Create lighter drafts while keeping your high-resolution source files untouched.

Worth knowing

Keep the output predictable

Quality is not a percentage saved

A quality value controls the encoder tradeoff. Actual savings depend on the source image and are measured after encoding.

PNG palette

Choose lossless to preserve decoded colors, or reduce the palette to 32–256 colors. A smaller palette can change gradients and is not suitable for every photo.

Target file size

Enter a target KB limit to search JPEG/WebP quality. If needed, dimensions are reduced as well. PNG target mode uses palette encoding and dimension reduction. Always check the actual result size.
