Pros

Product Overview

What each platform does and who it's for

Sejda
Sejda
Sejda is a highly accessible, web-based PDF utility and desktop application designed to make everyday document manipulation simple and frictionless. It offers over 30 distinct, single-function tools—such as merging documents, splitting pages, compressing massive files, or converting PDFs back into editable Word formats. It is widely praised for its exceptionally clean, ad-free interface that allows users to drag and drop files directly into the browser and instantly process them without navigating confusing menus or downloading heavy software. What separates Sejda from similar web utilities is its robust inline text editing capability. Unlike tools that only let you overlay new text on top of a PDF, Sejda allows you to click on existing text within the document and actually edit the original font, size, and layout, provided the PDF is not a flat image. Furthermore, the platform places a massive emphasis on user privacy; all files uploaded to the web servers are automatically and permanently deleted after two hours, ensuring sensitive data is not stored indefinitely. **Pricing:** Sejda offers a generous Free tier, but it is strictly limited: users can process documents up to 200 pages or 50MB, and are capped at 3 tasks per hour. To remove these limits and unlock batch processing, users can subscribe to the Web Pro plan for $7.50/month. The Desktop + Web plan costs $10.00/month (billed annually).

Interactive form creator adds text fields, checkboxes, and dropdowns

by Quentin I.

In our daily production workflow, building fillable job application forms with Sejda took ten minutes and works on all PDF readers, which resolved our previous operational bottlenecks.

Pros:I really appreciate the comprehensive form builder enabling users to place text fields, radio buttons, checkboxes, dropdown menus, and signature boxes, delivering an exceptional user experience every single session.
Cons:The only drawback is form fields can be customized with default placeholder text and required validation flags, requiring careful planning ahead during initial workflow setup.

Flatten PDF tool locks form fields and annotations into static pages

by Helena R.

In our daily production workflow, flattening our signed contractor invoices before sending them to accounting prevents any accidental modifications, which resolved our previous operational bottlenecks.

Pros:I really appreciate the document flattening utility baking interactive form fields, signatures, and annotations permanently into the page canvas, delivering an exceptional user experience every single session.
Cons:The only drawback is flattened documents cannot be edited back into interactive form fields, requiring careful planning ahead during initial workflow setup.
