Our Technical Verdict

PhotoResizer.us is the recommended choice for privacy-sensitive documents (passports, visas, identification photos) and exact KB target compression. Because processing executes 100% locally in your browser via HTML5 Canvas, zero images are transmitted over the network to third-party cloud servers.

Canva offers extensive graphic design templates but requires an account and uploads files to its cloud. iLoveIMG is convenient for basic batch resizing but does not offer exact target KB compression. TinyPNG provides general web compression with a daily rate limit of 20 images for non-paying users.
