Add PNG compression without dimension reduction

[fuleinist]

Problem

The existing PNG compression tool ("Downsample PNG") permanently reduces image resolution and dimensions. Users who just need a smaller file size — without changing image dimensions — have no option.

Solution

Add a new tool or toggle that applies lossless PNG compression (oxipng / optipng style) to reduce file size while keeping dimensions intact.

Use case

Users uploading images to sites with file size limits but strict dimension requirements (e.g., profile pictures, product thumbnails, site assets).

Scope (small)

• Add a new tool "Lossless PNG Compress" or add a toggle to existing tool
• Uses lossless compression algorithms (no dimension changes)
• Keep existing "Downsample PNG" tool unchanged for users who need dimension reduction

Hi, I’d like to work on this issue.

My plan:

• Add a new tool for Lossless PNG Compress
• Use a client-side library (i am thinking of UPNG.js) for lossless compression
• Keep dimensions unchanged
• Maintain consistency with existing UI

Let me know if this approach works.

Instead of creating a new tool, we can integrate this into the existing one by adding compression options (e.g., radio buttons)
