PNG files are much larger than JPGs, which is a problem when a form caps uploads at 100KB. Screenshots and graphics with text often start at several megabytes. Here is how to get any PNG down to 100KB, free, with no signup.
How to compress a PNG to 100KB
- Upload your PNG to the Trencada image compressor.
- Set the target size to 100KB.
- Compress and download the optimized file.
- Check that text and details still look sharp before uploading.
PNG vs JPG at 100KB: an honest note
PNG uses lossless compression, so a detailed PNG often cannot reach 100KB without help. Converting a photographic PNG to JPG usually solves it and gives far smaller files. The trade-off: JPG has no transparency, so transparent areas become a solid color. Keep the PNG format when transparency matters, and reduce the image dimensions instead.
Frequently asked questions
Can a PNG really shrink to 100KB?
Yes for simple graphics, logos and screenshots with flat colors. Detailed photographic PNGs may need conversion to JPG to reach 100KB.
Will I lose transparency?
If the PNG is converted to JPG for size, transparent areas become a solid color. Keep a PNG when transparency matters and shrink it by reducing dimensions.
Why are PNG files so big?
PNG compression is lossless, meaning it preserves every pixel perfectly. That quality comes at the cost of much larger files than JPG.
Is the PNG compressor free?
Yes. Free with no signup, no watermark and no limits.
