YL Yurii L. .NET Technology Lead Information Technology and Services Mid-Market (51-1000 emp.) 7/23/2026 "pdfFiller lets us update forms without rebuilding the whole workflow" 4.5/5 What do you like best about pdfFiller? We use pdfFiller when a workflow still depends on a PDF but doesn’t justify rebuilding the entire experience in Razor, Blazor, or a separate frontend. That’s where it has been most useful for me as a .NET Technology Lead. I don’t treat it as a backend, a database, or the place where business rules should live; it works best as the document layer around a process that still needs to generate, complete, and sign an approved file. The Online PDF Editor lets us correct text, add images, reorder pages, annotate content, and apply redactions without constantly going back to the source document. That saves more time than it sounds like, especially when we’re dealing with third-party forms or legacy PDFs and the requested change is nothing more than a label, date, or instruction. Magic Fields also gives us a practical head start by identifying lines and empty areas that are likely to be text, date, or signature fields. On a multi-page onboarding form, it produced most of the initial structure in seconds. It did miss part of a poorly aligned table and assigned a few fields incorrectly, but even with a quick review of names, roles, and positions, it was still much faster than placing everything manually from scratch.

Options for editing, converting, sending, signing, sharing, requesting information, and managing pages are all placed fairly close together, and the right action isn’t always obvious if you don’t already understand the workflow behind the document.

A client needed to digitize an authorization form while preserving the exact layout already approved by the legal department. Previously, users had to download the file, fill it out manually, sign it, scan it, and email it back. We uploaded the document to pdfFiller and used Magic Fields to generate an initial set of fillable fields. From there, we manually corrected field roles and positioning, then added Conditional Fields so that additional information appeared only when users selected specific answers. We published the flow through LinkToFill, and our .NET service generated the link from the active request and stored the external document identifier on the corresponding internal record. After the document was completed, we updated the request status and archived the final copy in line with the client’s retention policy. During testing, we found a flaw in our conditional logic: a required value could disappear if the same answer was changed twice. Instead of piling on more conditions inside the PDF, we simplified the form logic and kept the final validation in the backend before accepting the document. Overall, pdfFiller let us preserve the legal format without building another document editor, eliminated the download-and-email loop, reduced incomplete submissions, and provided proper traceability. Just as importantly, it connected the document to our application without turning the PDF into the place where every business rule had to be maintained. Review collected by and hosted on G2.com.
