Both tools deliver visually lossless compression on JPG and PNG. TinyPNG's pngquant-based pipeline is well-proven, and Glopix uses the same industry-standard Sharp library (backed by libvips) to achieve comparable file-size reductions. For most images, the difference in output size is under 3%. If compression quality alone is your only criterion, flip a coin — both are excellent.
TinyPNG does one thing well: compress JPG, PNG, and WebP. If you have a HEIC photo from your iPhone, a RAW file from a camera, or an AVIF image for your web project, TinyPNG can't help. Glopix handles 50+ formats natively. This is the most meaningful differentiator for most modern workflows.
TinyPNG's free tier lets you upload 20 images at once. Glopix imposes no batch limit — upload 200 product photos and compress them all in one go. For e-commerce teams, content teams, and agencies regularly processing large image sets, this is a significant practical advantage.
TinyPNG's WordPress plugin automatically compresses every image you upload to the media library. This is a clear win for WordPress publishers who want a "set it and forget it" approach. Glopix doesn't have a WordPress plugin and isn't trying to be one — it's a browser-based tool for active image-editing workflows.
