Why does Smallpdf lock users out after 2 operations?

Smallpdf operates on an aggressive freemium model that offers a quick preview before forcing users to purchase their paid plan. PDFBlack operates on client-side WebAssembly, making subscriptions obsolete.

Does PDFBlack have file size caps?

The only boundary is your local device RAM. You can easily process files with hundreds of pages and megabytes that other sites reject.

Are files saved anywhere after processing?

No. Files are held strictly in temporary volatile RAM in your browser tab and are cleared immediately upon closing or refreshing.
