IronTusk PNG Stomp 1.0 is now available for Windows.

I built PNG Stomp to simplify compressing image assets for my development projects. Add files or an entire folder, including its subfolders, choose an output folder, and compress the images through TinyPNG.

Features

500 free API compressions per account each calendar month

• Batch processing with drag and drop support.
• PNG, JPG/JPEG, WebP, and AVIF support.
• Compressed copies saved separately, preserving your originals.
• Numbered filenames to prevent duplicate names from overwriting each other.
• Batch progress, file-size savings, and monthly API usage reporting.

In one real test, a 64.1 MB PNG compressed to 3.6 MB, saving 94.3%. Results vary by image.

Price: $2.99, one-time purchase.

Requires 64-bit Windows on an Intel/AMD PC, an internet connection, and your own free TinyPNG Developer API key. Tested on Windows 11; Windows 10 compatibility has not yet been verified.

TinyPNG currently provides 500 free API compressions per account each calendar month, shared with other tools using that account. Images are uploaded to TinyPNG for compression. The app purchase does not include additional credits or a paid TinyPNG subscription.
