About Compress PNG
Compress PNG is built for the specific png image to compressed png workflow, not a generic upload page. Use it before uploading product photos, blog images, profile pictures, email attachments, or assets that need a smaller file size.
Processing happens locally in your browser where the selected format is supported, so files do not need to be uploaded for the normal workflow. The tool shows file details, output status, download actions, and practical warnings when a browser cannot safely decode or encode a format such as HEIC, TIFF, AVIF, or encrypted PDF.
Best practice: resize oversized images first, compare the preview, then choose the smallest file that still looks clean at the final display size.
Frequently Asked Questions
The browser decodes the image, draws it to canvas, and exports a smaller file locally when the format is supported.
