Guide for Compress PNG
Introduction
Reduce PNG size while keeping transparency and crisp edges for UI, logos, and screenshots.
When to use PNG compression
- Interface mockups and icons with transparency
- Screenshots for docs or tickets that are too heavy
- Logos you embed into decks, PDFs, or email signatures
- Images that should stay sharp but load faster on the web
How to use
- Prepare assets: keep originals and remove unused layers where possible.
- Upload PNG files (up to 500 MB) via button or drag-and-drop.
- Wait for optimization — the tool preserves transparency and fine edges.
- Download optimized PNGs. For extra savings, re-run or convert photos to JPG if transparency is not needed.
Tips and recommendations
- Crop extra whitespace before uploading to save more bytes.
- For photo-like images, try Compress JPG — JPG is smaller when transparency is not required.
- Keep a backup of the original file for future edits.
Example: UI kit export
- Upload icon sprites and UI screenshots.
- After compression they stay pixel-perfect, but attachments open faster for your team.
