PixCompress PNG to 100KB
PNG files are often much larger than JPEGs because PNG uses lossless compression by default. A screenshot or graphic saved as PNG can easily be 500KB-5MB. When you need that PNG under 100KB — for a web page, a form upload, or an email — Pixotter compresses it using advanced quantization while preserving transparency. Everything happens in your browser.

Why PNG Compression Is Different
Unlike JPEG, PNG does not discard visual information by default — every pixel is stored exactly. This makes PNG ideal for screenshots, graphics, logos, and images with transparency, but it also means PNG files are often 3-10x larger than equivalent JPEGs.
To compress a PNG to 100KB, Pixotter uses quantization — reducing the number of colors in the image while keeping it visually identical. A typical 256-color quantized PNG looks the same as the original to most viewers but can be 60-80% smaller.
When to Use PNG vs JPEG at 100KB
- Keep PNG when your image has transparency, text, sharp edges, flat colors, or is a screenshot or diagram
- Switch to JPEG when your image is a photograph without transparency — converting to JPEG will produce a much smaller file at the same visual quality
- Consider WebP — converting PNG to WebP gives you transparency support AND 25-35% smaller files
Tips for Hitting 100KB with PNG
If your PNG is a photograph (millions of colors), 100KB is very tight. Consider resizing to smaller dimensions first with the resize tool. For screenshots and graphics, quantization usually gets you there without visible quality loss.
If 100KB is too restrictive, try the 200KB target. If you need even smaller PNGs, the 50KB target covers extreme compression scenarios.
Frequently Asked Questions
How do I compress a PNG to 100KB?
Drop your PNG file on Pixotter. The compressor automatically adjusts quality to get the file under 100KB while preserving as much visual quality as possible. No signup or upload to a server required.
Will my PNG look different after compression to 100KB?
It depends on the original file size. If your PNG is close to 100KB, quality loss will be minimal. For larger files, Pixotter shows a before/after preview so you can check the result before downloading.
Are my images uploaded to a server?
No. All compression happens locally in your browser using WebAssembly. Your images never leave your device.
Is this PNG compressor free?
Yes, completely free with no limits. No account needed, no watermarks, no file count restrictions.
How It Works
Drag and drop any PNG image, including transparent PNGs. No signup required.
The compressor reduces colors and optimizes encoding to get your PNG under 100KB while keeping the image crisp.
Your compressed PNG is ready with transparency preserved. Check the before/after comparison.
