Free TinyPNG Alternative
TinyPNG is well known for image compression, but the free web version limits you to 20 images at once and uploads every file to their servers. Toolin compresses images entirely in your browser with no limits.
Why Switch from TinyPNG?
- Uploads images to TinyPNG servers for processing
- Free web tool limited to 20 images per batch
- API plan costs $25/year for 10,000 compressions
- No quality control on free tier
- No image resizing or conversion included
Toolin is 100% Private
Every tool runs entirely in your browser. Your files and data never leave your device — unlike TinyPNG which processes files on remote servers.
