Best Free Image Compression Tools Compared: TinyPNG vs Squoosh vs Compressor.io

January 11, 2026
8 min read

With dozens of image compression tools available, choosing the right one can be overwhelming. We tested the most popular free options to help you decide which tool best fits your workflow. Here is our honest comparison.

Why Image Compression Matters

Uncompressed images are the biggest contributor to slow websites. A single unoptimized photo can be 5-10MB, while a properly compressed version might be just 200KB with no visible quality loss. Faster sites rank higher on Google, convert better, and keep visitors engaged.

TinyPNG Review

TinyPNG has been an industry standard for years. It uses smart lossy compression to reduce PNG and JPEG file sizes while preserving transparency and visual quality.

  • Pros: Excellent compression quality, supports PNG and JPEG, has API and plugins
  • Pros: Clean interface, batch upload up to 20 images
  • Cons: Free tier limited to 500 images per month
  • Cons: Images are uploaded to their servers (privacy concern)
  • Cons: 5MB maximum file size on free tier

Squoosh Review

Squoosh is a free tool from Google Chrome Labs. It runs entirely in your browser, meaning your images never leave your device. Great for privacy-conscious users.

  • Pros: Supports WebP, AVIF, and other modern formats
  • Cons: Single image at a time only (no batch processing)

Compressor.io Review

Compressor.io offers both lossy and lossless compression options. It provides a good balance between simplicity and control.

  • Pros: Choose between lossy and lossless compression
  • Pros: Supports JPEG, PNG, GIF, and SVG
  • Pros: Clean, simple interface
  • Cons: Single image at a time
  • Cons: Images uploaded to server
  • Cons: 10MB file size limit

iLoveIMG Review

iLoveIMG is a comprehensive image editing suite with compression as one of many features. Popular for users who need multiple image operations.

Image Craft Hub takes a privacy-first approach with 100% client-side processing. Your images never leave your browser, making it ideal for sensitive content.

  • Pros: Complete privacy - images never uploaded to any server
  • Pros: Multiple tools in one place (compress, resize, convert, watermark)
  • Pros: Bulk processing with ZIP download (Pro)
  • Pros: Works offline as a PWA
  • Pros: No account required for basic use
  • Cons: 10 images per day on free tier
  • Cons: 10MB per image limit

Head-to-Head Comparison

Which Tool Should You Choose?

Choose TinyPNG if you need reliable compression with API access and do not mind server uploads. Choose Squoosh if you want maximum control and privacy for single images. Choose Image Craft Hub if you value privacy and need multiple tools (compress, resize, convert) in one place with batch processing options.

For most users, we recommend starting with a client-side tool for sensitive images and using server-based tools only for non-sensitive bulk work. The best tool is the one that fits your specific workflow and privacy requirements.
