As answered by people managing Squoosh and Docsworker.
Docsworker's answer:
Docsworker runs every tool entirely inside the user’s browser, so files are never uploaded to a server. It offers 12 PDF and image tools in one place, including on-device OCR, a PDF text editor and a text-to-handwriting converter, with no sign-up, no daily limits and no watermarks.
Docsworker's answer:
Most popular PDF tools upload your files to their servers and limit free use with caps, watermarks or paywalls. With Docsworker your documents never leave your device, which makes it safer for IDs, contracts and resumes. It is also free with no account needed, and conversions are fast because there is no upload or download wait.
Docsworker's answer:
Students, job seekers, freelancers and office workers who need quick, everyday PDF and image tasks such as converting JPG to PDF, extracting text with OCR, signing documents or editing a PDF. It is especially useful for people who handle sensitive documents and care about privacy, and for people on mobile or slow connections.
Docsworker's answer:
Docsworker was built to offer simple PDF and image tools without the privacy trade-off of uploading files to unknown servers. The goal is a fast, free toolbox that works in any browser, with no sign-up or limits.
Docsworker's answer:
eact, TypeScript, Vite and Tailwind CSS, built as a fast static website. The tools run client-side using WebAssembly, Web Workers and HTML5 Canvas.
Docsworker's answer:
Students, job seekers, freelancers and office workers who need quick PDF and image tasks like JPG to PDF, OCR, signing and editing PDFs, especially people who want to keep sensitive documents private.

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 / about 1 month ago
