PhotoFileSize vs TinyPNG

Both tools compress images, but they take very different approaches. Here's an honest comparison so you can pick what fits.

Privacy

PhotoFileSize: 100% in your browser. The image never leaves your device.
TinyPNG: Uploads your image to their servers for compression.

Compression quality

TinyPNG uses excellent perceptual algorithms and often achieves smaller files at the same visual quality, especially for PNG. PhotoFileSize uses standard browser JPEG/WebP encoders with binary-search quality targeting — very good for hitting an exact KB target.

File size targeting

PhotoFileSize lets you target an exact size (50 KB, 100 KB, custom). TinyPNG compresses but does not target a size.

Document photo support

PhotoFileSize includes 30+ presets for passport, visa, CV, social. TinyPNG is compression-only.

Cost & limits

PhotoFileSize: unlimited, no signup. TinyPNG: free tier 20 images/month, paid above.

Bottom line

If privacy or exact file-size targeting matters, use PhotoFileSize. If you want best-in-class PNG compression and your images are not sensitive, TinyPNG can produce smaller files.
