Solo builder. I run image infrastructure for my own projects and kept being annoyed by two things in existing services: APIs that report "savings" while quietly returning a bigger file, and error responses that change shape between endpoints.
So Tinify.dev's API has a short contract: compression never returns a file larger than the input (you get optimized: false and your original bytes back - resize and crop report size changes plainly, and format conversion can legitimately grow a file), one error envelope everywhere (code, message, request_id), required idempotency keys, batch up to 200 files. Kotlin/Spring + sharp on a Hetzner box.
The launch hook: there's now an MCP server (npx -y @tinify-dev/mcp), so an AI agent can compress, resize, crop, or convert local images mid-task - output goes next to the input, never overwriting the source. Plus a GitHub Action that compresses images in PRs and posts a savings table.
Free: web tools with no ads or signup; API at 500 operations/month with no card. Paid from $9/mo (2,000 ops) and $29/mo (10,000).
Limits, stated plainly: 40 MB / 50 MP per image, results expire after two hours, one machine, no SLA on the free tier.
Not affiliated with Tinify B.V. (TinyPNG). Questions welcome - I'll be here all day.
finally a no signup image tool that just works. ran a few pngs through and the before/after stats right on the page saved me from guessing
The clean display of file size savings and quality metrics right next to the preview is genuinely useful, not just decorative. Love that you support AVIF and WebP without making it feel like a tacked-on feature.
