sample testing VS Squoosh

• Cost-Effective
  Sample testing allows for evaluation of smaller groups from a larger population, reducing the resources and time required compared to testing the entire population.
• Efficiency
  Sample testing speeds up the process of data gathering and analysis, enabling quicker decision-making and implementation of findings.
• Feasibility
  Testing samples makes it feasible to conduct studies or experiments in cases where testing the whole population is impractical or impossible.
• Focused Insights
  Allows researchers to focus on a specific section of the population, providing detailed insights into that segment.

Possible disadvantages

• Sampling Error
  There is always a chance that the sample may not accurately represent the population, leading to errors in conclusions.
• Bias
  If the sample is not chosen carefully, it can lead to biased results that do not reflect the true characteristics of the population.
• Data Limitations
  Limited sample sizes may not capture all variations within the population, potentially ignoring important sub-group differences.
• Dependence on Sampling Method
  The quality and reliability of the results are highly dependent on the sampling method used; poor sampling techniques can invalidate the results.

• Free to Use
  Squoosh is a free web application, which makes it accessible to anyone without the need for a subscription or payment.
• User-Friendly Interface
  The application features an intuitive and easy-to-navigate interface that simplifies the image compression process.
• Multiple Formats Support
  Squoosh supports a wide range of image formats including JPEG, PNG, WebP, and AVIF, allowing for versatile usage.
• Real-Time Comparison
  Users can compare the original and compressed images side-by-side in real time, providing immediate visual feedback on the compression quality.
• Customization Options
  The app allows users to adjust various parameters such as quality, resizing, and other advanced settings for greater control over the compression.
• Open Source
  Squoosh is an open-source project, meaning that its code is transparent and can be reviewed, modified, and improved by the community.
• Offline Capability
  The application can also be used offline, adding a layer of convenience for users who may not always have consistent internet access.

Possible disadvantages

• Limited Advanced Features
  While great for basic compression tasks, Squoosh might lack some advanced features found in professional image editing software.
• File Size Limits
  There might be limitations on the size of the files that can be uploaded and processed, which could be a constraint for users dealing with very large images.
• Web-Based Dependency
  As a web application, its performance can be influenced by the browser and device capability, which could vary significantly among users.
• No Batch Processing
  Squoosh is designed for single-image processing. Users looking to compress multiple images at once will find this feature lacking.
• Privacy Concerns
  Although it can be used offline, the nature of a web app raises concerns for users who prioritize privacy and data security.
• Limited Support Resources
  Being a free tool, it doesn't come with professional support, so users might have to rely on community forums or documentation for help.

  The only negative thing about this web app, is that it's not clear which formats are supported in which browsers.

Tracking sample testing since Sep 2022.

  WebP/AVIF over PNG/JPG: Converted all icons to WebP (using Squoosh) – average size reduction of ~60% (e.g., a 40KB PNG icon became 15KB WebP). - Source: dev.to / 8 days ago

• Firefox intent to ship: JPEG XL

  It often comes down to compat, and developer requests. Personally I find in-browser encoding for images inadequate, because it doesn't expose enough options. When we built https://squoosh.app/, we exposed the browser encoders for... - Source: Hacker News / about 1 month ago

• Can you build a recognizable World Map in under 500 bytes?

  Its a fun challenge. I used https://squoosh.app to make a pretty good one. Mostly just a resize and then OxiPNG for compression. Managed a 124x62 black/white image. OP has a resolution of 195x53, so I had very similar, but slightly worse... - Source: Hacker News / 3 months ago
