As answered by people managing Sejda and Partstack.
Partstack's answer:
We're a next-generation search engine and digital marketplace for semiconductor and electronic component buyers & traders. Partstack was designed for today’s globally connected marketplace. One key difference is that we’re not a "pay-to-play" platform. Customers never pay a dime and approved suppliers can display their in-stock inventory without restriction.
Users can find more parts, more suppliers, and radically transparent pricing and inventory data—faster than ever before.
Partstack's answer:
We've assembled the world's largest semiconductor supply chain and supercharged it with the power of modern search technology. And we're iterating and improving our marketplace every single day.
Partstack features the most diverse and comprehensive supplier stack of all electronic component marketplace platforms. Most importantly, our extensive component catalog is shared with users via product-rich data pages that feature insights that are simply not available on any other platform. In addition to form, fit, function, and standard trade compliance data, users can find information about part manufacturer leadership, financials, fab locations, and other key data points.
Partstack's answer:
Our primary audience consists of the builders, makers, and innovators who create the products that power our world. We built Partstack to make life (and sourcing!) easier for these everyday game-changers (i.e., electrical engineers, PCB design teams, semiconductor procurement professionals, distributors, product manufacturers, students, etc.). Whether they are independent hobbyists, a company of one, or a large-scale corporation (OEM/CM)—we make it easy for users to find their place in the stack.
Partstack's answer:
The platform is the brainchild of a team of electrical and software engineers who wanted to build the world’s most comprehensive electronic components database and marketplace platform. We like to say that Partstack was built for engineers, by engineers with one goal in mind: Marketplace diversity and transparency.
Partstack's answer:
An array of cutting-edge technologies come together to build our platform's "technological harmony." We take advantage of both client-side and server-side rendering to parse and manage the flow of data across our multi-vendor marketplace. We utilize direct supplier uploads and some programmatic interfacing to collect real-time pricing and inventory data to populate our supplier stack. Technologies such as Cloudflare and SSL certificates are used to ensure user authentication, data encryption, and overall platform security. Finally, several in-house, custom-built proprietary technologies are used to power our search engine, stack logic, and other features of our marketplace.
Partstack's answer:
Partstack supports users from the world’s largest manufacturing companies (OEMS) and contract manufacturers. We also proudly serve tinkerers and hobbyists.

This is a week late, but through the FreeMediaHeckYeah sub, I was able to discover sejda.com , which is basically an (almost) all-in-one PDF editor website. Was neat to realize I didn't even have to download any software whatsoever. Source: over 3 years ago
Sejda.com - By far my most favorite experience but limits you to a # of docs per day. Source: about 4 years ago
Might try sejda.com. Also as u/jakethepeg111 suggests, Libreoffice Draw could be an option. Source: about 4 years ago
