What Lossless Compression Does
- Re-optimizes PNG structure and compression blocks.
- Removes unnecessary metadata where safe.
- Keeps alpha transparency and edges clean.
Lossless Optimization
Compress PNG Without Losing Quality
PNG is perfect for logos, UI assets, and screenshots with transparency. Use a lossless workflow to reduce size while keeping every visible pixel identical.
What It Does Not Do
- It does not blur, resize, or alter visible detail.
- It cannot fully fix oversized dimensions.
- It is not always the best choice for photo-heavy images.
Lossless PNG Playbook
-
Step 1
Start from original design exports (avoid repeatedly re-processing previously optimized files).
-
Step 2
Upload PNG files to Image Compressor.
-
Step 3
Review output size reduction and inspect transparent edges at 100% zoom.
-
Step 4
If files remain large, resize dimensions or switch photo-like graphics to WebP/AVIF.
PNG vs Modern Formats (Quick Decision)
Use PNG When
You need crisp transparency, flat graphics, logos, and broad editing compatibility.
Use WebP When
You want strong compression with broad support and fast encode workflows.
Use AVIF When
You prioritize smallest payloads and can accept slower encode times.
Frequently Asked Questions
-
Yes. Lossless PNG optimization reduces file size without changing visible pixels.
-
Large dimensions and complex transparency can keep PNG size high. Consider resizing or converting photo-heavy PNGs to WebP/AVIF.
-
No. JPG does not support transparency and introduces lossy artifacts, so it is not ideal for logos/UI graphics.
-
Yes. The compressor supports batch uploads and ZIP download for quick processing.
