Features and specs

What each product offers, as listed by its team.

Squoosh 7 features
DevelopK PDF Tools 5 features
  • 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.
  • Browser-based convenience
    As an online PDF toolkit, it generally needs no software installation. Users can open the site and handle common PDF tasks such as merging, splitting, compressing or converting from any device with a browser. I could not browse the site, so the exact tool list is unverified.
  • Accessible, no-friction workflow
    Web-based PDF utilities like this typically have a simple upload, process and download flow. That makes them approachable for non-technical users who need a quick one-off task.
  • English-language interface
    The URL path (/en/) indicates an English version of the site. This makes the tools usable for international users beyond the Korean market the developer appears to be based in.
  • Cross-platform compatibility
    Because the tools run in a browser, they should work on Windows, macOS, Linux and mobile devices without platform-specific installers.
  • Likely low cost or free for basic use
    Small independent PDF tool sites often offer basic features free or at low cost compared with full desktop suites like Adobe Acrobat. Check the site for current pricing and limits.

Questions & Answers

As answered by people managing Squoosh and DevelopK PDF Tools.

What's the story behind your product?

DevelopK PDF Tools's answer:

FastestPDF started because PDF tool sites kept requiring sign-up or adding watermarks for simple tasks like merging a few pages. It's one of four free tool sites built and maintained by a solo indie developer (alongside developk.kr, Pixzero, and FastestUnitConverter), focused on PDF-specific tasks like merging, compressing, and converting.

What makes your product unique?

DevelopK PDF Tools's answer:

FastestPDF offers 13 free PDF tools (merge, split, compress, convert, watermark, and more) you can use instantly in your browser. Files are never uploaded to a server — everything is processed client-side using pdf.js and pdf-lib, so sensitive documents stay private.

Why should a person choose your product over its competitors?

DevelopK PDF Tools's answer:

Many PDF tool sites require sign-up, add watermarks, or upload your file to a server before processing it. FastestPDF skips all of that — no account needed, and because processing happens entirely in the browser, it's safe to use with contracts or documents containing personal information.

How would you describe the primary audience of your product?

DevelopK PDF Tools's answer:

Anyone who occasionally needs to merge, split, compress, or convert a PDF without installing software or creating an account — freelancers handling contracts, students, and office workers who just need a quick, one-off PDF fix.

Which are the primary technologies used for building your product?

DevelopK PDF Tools's answer:

FastestPDF is a static HTML/CSS/JavaScript site (PWA) using pdf.js and pdf-lib for in-browser PDF processing — no backend, no file uploads.

    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 / 2 months ago
