About Compress PNG to 100KB – Transparent & Lossless Reducer

Compress PNG graphics to 100 KB or less with transparent choices: preserve lossless PNG format or convert to modern WebP.

The image is decoded and processed locally in your browser; it is not uploaded to Navorika.

How to use this tool

  1. 1Select a PNG image with or without transparency.
  2. 2Choose Mode A (Preserve PNG) or Mode B (Smaller File via WebP).
  3. 3The engine re-encodes the image and downscales dimensions only if necessary to stay under 100 KB.
  4. 4Download your 100 KB image.

Understanding the result

Canvas PNG encoding is lossless, meaning quality sliders have no effect on raw PNG byte size.

Mode A adjusts pixel dimensions to hit 100 KB losslessly, while Mode B uses lossy WebP to preserve transparency at full dimensions.

Important limitations

  • Complex PNG screenshots with text may lose sharpness if dimensional downscaling is required in Mode A.
  • Color quantization (8-bit indexed PNG) is not executed in browser canvas.

Frequently asked questions

Why cannot PNG be compressed with a quality slider?

PNG is a strictly lossless compression format. HTML5 Canvas ignores quality arguments for image/png. File size can only be reduced by downsizing dimensions or converting to WebP.

Does Mode B keep transparency?

Yes. When converting to WebP in Mode B, full alpha transparency is preserved.

Are files processed locally?

Yes. Processing runs entirely on your device with no server upload.
