Can PNG be compressed without losing quality?

PNG supports lossless compression, meaning you can optimize the compression level without changing pixel data. However, the size reduction from true lossless optimization is limited (typically 5–15%). For major size reductions, some quality trade-off is required.

Why are PNG files so large compared to JPEG?

PNG uses lossless compression, which preserves every pixel exactly. JPEG uses lossy compression, which discards fine detail to achieve much smaller file sizes. A PNG of the same photo is typically 3–5x larger than an equivalent JPEG.

Should I use PNG or JPG for web images?

Use PNG for logos, icons, screenshots, and images with transparency or sharp text. Use JPG for photographs. WebP is the best choice for both types on modern browsers.

Does compressing PNG remove transparency?

No. Compressing a PNG with FixTools preserves the alpha channel (transparency). Converting to JPG will remove transparency — JPG does not support it.

What is the best way to reduce PNG file size?

For the largest reduction: convert to WebP using the Format Converter. For keeping it as PNG: reduce image dimensions first using the Image Resizer, then apply PNG compression.

Can I compress PNG files on iPhone or Android?

Yes. FixTools runs in mobile browsers and works with PNG files from your camera roll or files app.

Compress PNG Without Losing Quality

PNG files are larger than JPEGs because they use lossless compression. FixTools offers two approaches: lossless PNG optimization (no quality loss, moderate size reduction) and lossy PNG compression (significant size reduction with minimal visible degradation). Choose the right method for your use case.

How to use this tool

💡

Upload your PNG. For lossless compression, use a high quality setting (90–100%). For maximum size reduction with acceptable quality, use 75–85%.

How It Works

Step-by-step guide to compress png without losing quality:

1
Upload your PNG file
Open the Image Compressor and upload your PNG image.
2
Choose your compression approach
For logos and graphics with transparency: use quality 90–100% for lossless-like results. For photos saved as PNG: convert to JPG or WebP first for drastically smaller files.
3
Check transparency is preserved
If your PNG has a transparent background, verify the compressed PNG maintains it after downloading.
4
Download the compressed PNG
Save the optimized PNG file.
