About CompressImg
A free image compression tool with clear data-handling disclosures.
CompressImg is a free online tool designed to help you compress images quickly and easily. Images are sent over HTTPS through our Cloudflare Worker to TinyPNG for perceptual optimization; if further reduction is needed, a local Canvas re-encode is performed in your browser.
Our mission is simple: provide fast, reliable compression with honest explanations of where image processing occurs.
Our Story
CompressImg was created out of frustration with existing image compression tools. Many online compressors require you to upload your images to their servers, raising privacy concerns. Others are cluttered with ads, require registration, or limit the number of images you can compress. We set out to build something better - a tool that respects your privacy, works instantly, and never asks for personal information.
How It Works
CompressImg uses a two-stage approach: images are first sent to TinyPNG through our HTTPS Worker. The Worker keeps no image copy, while TinyPNG may temporarily retain submitted content for up to 48 hours under its terms. If the result is above your selected limit, the browser adjusts JPEG quality and dimensions locally.
Our Values
Privacy First
Our Worker keeps no image copy, and we disclose TinyPNG's temporary retention period instead of claiming processing is fully local.
Fast & Simple
No registration, no waiting. Compress images in seconds with an intuitive interface.
Completely Free
No hidden costs or subscriptions. The TinyPNG stage has a fair-use quota, with local compression available as a fallback.
Quality Results
Smart compression algorithm finds the best quality for your target file size.
