5. Result inspector

Compare before and after before the ZIP download.

Sort results, expand the per-file details, and open the side-by-side inspector.

What this tool does

Image Compressor & Converter handles mixed JPG, PNG, WebP, and BMP batches locally in your browser for compression, conversion, resizing, and export prep.

When to use it

PNG boundary

Use this tool for mixed formats, conversion, or resizing. Use PNG Compressor when the entire batch is PNG-only and the goal is stronger PNG-specific reduction.

BMP support

BMP files can be added to the shared queue and exported locally as JPG, PNG, WebP, or AVIF when the runtime browser path supports that output type. BMP export is not offered as a browser output target.

Privacy

Core compression, conversion, resizing, preview rendering, and ZIP creation run locally in your browser. No upload is required for the main workflow.
