Is a PDF Optimizer Online Really Helpful for Web Designers?

I was recently searching for reliable PDF tools and came across a pdf optimizer online that actually works smoothly compared to many cluttered or poorly designed sites out there. A lot of PDF converters on the web look outdated, are full of ads, or don’t even function properly, but this one felt fast, clean, and user-friendly — something we rarely see these days.

It made me wonder:

Have you tried any online PDF optimization or compression tools that genuinely work well?

Do you think web design quality affects how much we trust tools like these?

As web designers, do you also judge these platforms based on UI/UX before trusting them with your documents?

For me, a tool’s interface, speed, and smooth workflow matter just as much as its features. When a website is well-designed, loads quickly, and keeps things simple, it instantly feels more reliable.

What do you all use for optimizing PDF files, and which sites do you think are designed well enough for professional-grade work?
