What it does
TinyPNG offers image compression and conversion, with a developer API, integrations and an image delivery service under the Tinify brand.
Drop web images into the compressor and select a conversion format when needed. Web Free allows 20 compressions and three conversions per session, with a 5 MB limit per image. Pro raises compression to unlimited and size to 75 MB but keeps the conversion cap; Ultra allows 150 MB images, unlimited conversions and folder uploads. Paid features need login. Compression is lossy and strips metadata, which may change DPI or colour-profile defaults. Tinify states uploads are retained for at most 48 hours. API and CDN access have separate terms.
