What is Fill?

The Quickest Way to Fill Out, Send, and Sign PDFs. PDFs serve various functions, such as legal agreements, application submissions, and business contracts. Although Adobe offers a paid software solution, it tends to be costly, slow, and requires substantial storage space on your device. Alternatively, Fill is a free online PDF tool that provides a fast method for signing, completing, or dispatching forms for others to fill out and sign. With its built-in email feature, you can easily send documents directly from Fill, including a custom subject line and message for better communication. Additionally, all completed forms are securely stored in your Fill account, giving you an organized record of who signed what and when, which simplifies the process of tracking signatures. This tool enhances the efficiency of managing PDFs, ultimately saving you both time and resources, and allows for easier collaboration among users.

What is BoostPDF?

BoostPDF is an online PDF editor with more than 30 tools in one place. It runs in the browser on Windows, Mac, Linux, Chromebook, phones and tablets, and there is an Android app that adds a document scanner. What it does - Edit the existing text in a PDF, and add text, images, drawings, highlights, stamps, QR codes and barcodes - Sign documents with a drawn signature and fill in forms - Merge, split, rotate, reorder, crop, add and remove pages - Compress PDFs, including to a target size such as under 1 MB - Convert PDF to and from Word, JPG and PNG - OCR scanned PDFs in 19 languages - Permanently redact sensitive text, with optional withholding grounds - AI summaries, translation into 37 languages, quizzes and chat with page references Where your file goes Signing, annotation, form filling, redaction and page tools work in the browser without uploading the file. Compression, conversion, OCR and password protection use BoostPDF's servers, which delete uploads right after processing; result links expire within an hour. AI tools send the document text to an AI provider. Pricing The free plan has daily limits per tool and a 10 MB file limit. BoostPDF Pro is US$6.49 per month or US$62.30 per year, with no daily limits (OCR and AI tools keep fair-use caps) and files up to 100 MB.
