What we do
tdd8.cn splits the most common image chores into one page each: compress, compress to a target KB, resize, crop, watermark, convert formats, generate ICO files, turn JPGs into a PDF, batch-process marketplace images, and more. Every page solves one problem, the settings are written in plain language, and everything works the moment you open it.
Why we keep processing local
Most image work does not need a server at all: compressing, scaling, cropping and text watermarks can all be done by Canvas in your browser. Doing it locally has two benefits—your files never leave your computer, so privacy stays under your control, and nothing queues for a server, so even 300 images run through one by one.
Only features that need model inference—AI cutout, old photo restoration, OCR—run server-side. Those files are deleted right after processing and are never kept.
Technology and principles
- The core tools are free to use, with no forced registration and no watermark;
- Every page is rendered server-side, so search engines can crawl it and you can bookmark a direct link;
- No forced sharing, no pop-ups, no hijacked downloads.
