FormForge vs Sejda PDF Forms

FormForge is a free browser-based tool for turning existing PDFs into fillable forms. Its AI detects fields in flat PDFs and scans, running locally in the browser through WebAssembly. Users can add text, checkbox, radio button, dropdown, signature, date, and number fields, then run Form doctor’s 21 AcroForm checks with one-click fixes. CSV data can be used to generate batches of completed PDFs. Signatures can be drawn or typed in a handwritten style; an optional cryptographic signature can be added on export. Processing and drafts stay on the device in the browser. The installable PWA works offline once its resources are cached, but opening or reloading the page requires a connection. Exports include AcroForm PDFs and ZIPs of filled PDFs, which the site says open in several desktop and mobile PDF readers. FormForge does not edit underlying PDF page content or reorder, delete, rotate, or merge pages. It has no fixed file-size or page-count limit, though practical limits depend on device memory. The free plan requires no account or credit card and has no watermark or page limit.

Sejda PDF Forms creates fillable PDF documents from an existing PDF or a blank document. Form fields include text boxes, textareas, radio buttons, checkboxes, dropdowns, and signature boxes. Fields can be required, assigned character limits, set with alignment and font options, and arranged in tab order. Publishing creates a shareable, non-expiring link for others to fill and sign the form, then return it by email. Online uploads can come from Dropbox, Google Drive, OneDrive, a web address, or a local computer. The free online service allows documents up to 200 pages or 50 MB and three tasks per hour. Sejda offers web and desktop access on Linux, macOS, and Windows. Desktop processes documents locally; online documents are encrypted in transit and at rest. Sejda says it does not offer document storage, and published forms are saved in the user's Google Drive with public link access. Editing existing text in scanned documents is not supported, though new text, images, and annotations can be added. Paid options include a 5.00 USD one-time Web Week Pass and a $7.50 a month Web Monthly plan.
