Why Developers Look for TinyPNG Alternatives
TinyPNG is the go-to image compressor for web developers and designers. It produces excellent results, but its free tier has meaningful limitations:
- •5MB file size limit — Images larger than 5MB are rejected on the free tier. Modern cameras produce 10-30MB photos.
- •20 images per batch — Free users can only compress 20 images at once. For a product photoshoot or website migration, this means multiple sessions.
- •Server upload required — Every image is uploaded to TinyPNG's servers (owned by Tinify) for processing. Your product photos, client assets, and personal images pass through third-party infrastructure.
- •API pricing — The API costs $25/year for 10,000 compressions. Heavy users need the paid tier.

MiOffice compresses images entirely in your browser using Canvas APIs and optimized JavaScript compression algorithms. Your images never leave your device.
