TinyPNG alternatives: free compressors, including private ones

TinyPNG is a solid image compressor, but it uploads your images to its servers and limits free use. If you want something that keeps images on your device — or just more formats and no caps — here are the main alternatives and how they compare.

Why look for a TinyPNG alternative?

TinyPNG does one thing well, but a few things send people looking for alternatives.

  • It uploads your images to its servers to compress them — not ideal for private or sensitive photos.
  • The free web version is limited (around 20 images at a time, each under 5 MB); heavier use needs a paid plan or API key.
  • It focuses on PNG, JPG, and WebP — no PDF tools or one-click format conversions.

TinyPNG alternatives compared

The most useful thing to know about each alternative is whether it uploads your file (accurate as of 2026 — check each tool's current docs, since services change).

Which alternative fits you?

Pick based on what matters most.

  • Want it private and no-upload, across formats and PDF? Pixo compresses everything in your browser, one click, no sign-up.
  • Want deep manual control of a single image? Squoosh is excellent and also fully client-side.
  • Optimizing a whole site's assets in bulk and fine with a server? iLoveIMG has generous batch tools (your images are uploaded).
  • Just want a drop-in TinyPNG replacement for a few PNGs? Any of the above works; choose by whether upload matters to you.
