TinyPNG Alternative Chrome Extension: Online Image Compressor vs Extension - Photo Compressor

The other trigger is more specific: does the image get uploaded to a server? With TinyPNG, yes. Files are sent to Tinify B.V.’s infrastructure, held temporarily, optimized, and — per the company’s own policy — deleted within 48 hours, while request logs (browser type, IP address, API key, timestamp, and a fingerprint of the transferred file) are retained for up to 31 days. That is not a security flaw; it is simply a different model. TinyPNG promises to delete your file. A Chrome extension that compresses locally never receives it in the first place, so there is nothing to delete.

None of these four tools is a lesser product just because a browser extension exists. Each one wins outright in at least one dimension.

Setting a target weight in kilobytes replaces the guesswork of a quality slider — none of the four online tools offers it. A side panel instead of a popup. Every one of the tools above works in a tab or a popup that closes the moment you click away. Photo Compressor’s side panel stays open in Chrome while you switch tabs and collect images, which is a small thing until you are gathering files from six different pages at once.

Right-click any image on a page. The “Compress Image” entry in the right-click context menu compresses an image directly off a web page — no separate download-then-upload step first.
