Frequently Asked Questions
How to compress a PNG file?
Upload your PNG file, adjust the quality and max width settings, and click Compress. Since PNG is lossless, quality adjustment mainly affects dimensions. Setting a max width is the most effective way to reduce PNG file size.
Can I compress PNG without losing quality?
PNG is a lossless format, so the quality slider has no effect on PNG files. To reduce PNG size without quality loss, you can only reduce the image dimensions. For better compression with quality control, consider converting to WebP.
How much can I reduce PNG file size?
By reducing dimensions, you can typically achieve 30-70% size reduction. For example, scaling a 4000px wide image to 1920px can reduce file size by 75% or more.
What is the best way to compress PNG for web?
For web use, resize your PNG to the maximum display size needed. A 1920px wide image is usually sufficient. Alternatively, convert to WebP for 25-34% better compression.
