Compress PNG Without Losing Quality

Why Choose Image Toolkit

Pixel-Perfect Lossless

Re-encoding removes redundant metadata without changing a single pixel.

Transparency Preserved

Alpha channels stay fully intact — logos and UI assets keep their transparent backgrounds.

Designer & Developer Friendly

Safe for app icons, game assets and client deliverables where quality is non-negotiable.

How to Use

1
Upload an image
Click the upload area or drag & drop a JPG/PNG image onto the page.
2
Choose compression quality
High quality (near-lossless), Balanced (best for web), or Maximum compression (smallest size).
3
Download the result
Compare the file size and savings percentage, then download with one click.

Designers and developers often avoid PNG compression for fear of quality damage. Lossless re-encoding removes that trade-off entirely: the file gets smaller, and the pixels stay identical.

How lossless compression works here

Upload your PNG.
Keep the default Balanced quality — this mode is lossless for PNG.
Download the re-encoded file; the preview confirms the savings.

When quality can’t be compromised

Client deliverables — logos and mockups sent to stakeholders.
Game & app assets — sprites and icons where pixel fidelity matters.
Archival — screenshots and documents you need to store long-term.

Private, always

Compression runs locally in your browser with no upload. Your PNG never leaves your device.

Frequently Asked Questions

What does lossless PNG compression actually do?

It removes redundant data — like unused color profiles and metadata — and re-encodes the image more efficiently. The visual result is identical to the original.

How much can I save without losing quality?

Typically 20–40% on screenshots and design exports. Savings depend on how much redundant data the file contains.

Will transparent areas be preserved?

Yes. Lossless mode keeps PNG format and alpha transparency completely intact. JPEG conversion only happens if you choose Maximum on an image without transparency.
