Compress PNG to 150KB Online — Balanced Quality for Web Graphics
Reduce PNG images to 150KB or less for blog thumbnails, social media graphics, email banners, and WordPress images.
Compress a PNG to 150KB when 100KB removes too much detail but 200KB is larger than your web budget. This middle target is built for blog thumbnails, social media graphics, email banners, WordPress featured images, and other medium-weight web graphics that need a practical balance between visible detail and file size.
Unlike a strict form-upload limit, a 150KB target is usually about performance and presentation. The tool accepts PNG, JPG, JPEG, and WebP input and always exports PNG. It checks whether your image already meets the limit, then reduces pixel dimensions only when necessary. Because PNG is lossless, the optimizer cannot use a JPEG-style quality slider—it finds the largest practical dimensions that fit under 150KB. A retained-width indicator shows how much of the original width was kept, and the result panel reports the actual file size and dimensions. Processing stays in your browser; the image is not uploaded to WeLuvTools.
