TinyPNG VS SizeSpec

• High Compression Efficiency
  TinyPNG uses advanced lossy compression techniques to reduce the file size of PNG and JPEG images substantially without noticeable loss in quality.
• Supports Multiple Formats
  The service supports various image formats, including PNG and JPEG, making it versatile for different types of image optimization needs.
• User-Friendly Interface
  The interface is straightforward and easy to use, allowing users to drag and drop images for quick compression.
• Batch Processing
  Users can compress multiple images simultaneously, which saves time and improves productivity.
• API Access
  TinyPNG offers an API that allows developers to integrate its functionality into their own applications, providing automated image compression capabilities.

Possible disadvantages

• File Size Limitations
  The free version of TinyPNG has file size limitations, restricting the size of images that can be uploaded and compressed.
• Limited Free Usage
  Users are limited to a certain number of free compressions per month, which may not be sufficient for heavy users or large projects.
• Lossy Compression
  The lossy compression technique, while effective, may not be suitable for applications requiring completely lossless compression.
• Dependency on Internet Connectivity
  TinyPNG is an online tool, so users need an active internet connection to leverage its services.
• Subscription Costs
  Advanced features and higher usage limits require a subscription, which could be a deterrent for budget-conscious users.

• Marketplace presets
  Etsy, eBay, Amazon, Shopify, WooCommerce, App Store and Google Play size/aspect/file-size rules, each linked to the marketplace's own seller docs
• Client-side processing
  Photos are resized, cropped and compressed in the browser (createImageBitmap + canvas); nothing is uploaded to a server
• Free converters
  JPG, PNG and WebP conversion, free, with no account and no limit
