📝 HelloSign (Dropbox Sign) is a signing tool only — it does not let you fill in PDF form fields, type into blank lines, or check boxes.
Most people searching for a HelloSign alternative have a broader problem than signing alone. They need to fill out a PDF form — a W-9, a rental application, a government document, a job application — and then sign it. HelloSign was never built for that. It is a signature-collection workflow tool, not a form-filling tool. If you open a PDF in HelloSign and try to type into a blank field, you will quickly find that it cannot do what you need.
This guide covers the best free tools for filling out PDF forms and signing them in 2026. Whether you have a tax form to complete, a rental application to submit, or an employment document to fill and sign, these alternatives handle both steps that HelloSign cannot.
The tools reviewed here were chosen based on four criteria: whether they can genuinely fill PDF form fields (not just add a signature), whether they require an account to use, whether they work on mobile devices, and whether they are free without a document cap that cuts you off mid-month.
Why HelloSign Falls Short for PDF Forms
HelloSign, now rebranded as Dropbox Sign, was designed for one specific workflow: you send a document to someone, they sign it, and you get a signed copy back. That is a useful feature for collecting client signatures on contracts. It is not useful when you are the person who needs to fill out a form and return it.
The distinction matters more than it might seem at first. When you receive a W-9 request from a client, a rental application from a landlord, or a benefits enrollment form from your employer, those documents have blank lines and boxes waiting for your name, address, tax ID number, date, and dozens of other fields. HelloSign has no way to fill those in. It can only capture a drawn or typed signature and place it on the document. The text fields, checkboxes, and date fields are invisible to it.
This limitation sends many users on a frustrating detour. They realize midway through trying to process a document in HelloSign that they also need to type their information into fields — and they have to start over in a different tool. A better approach is to use a tool built for form filling from the start, one that also lets you add a signature when you are done. That combination covers the complete workflow without juggling multiple applications.
The paid Dropbox Sign plans add some annotation features, but the core product is still not designed around PDF form filling the way dedicated tools are. And at $15 to $25 per month depending on the plan, it is a significant expense for a workflow that free tools handle better.
How to Fill a PDF Form Free with SignMyPDF Fill
SignMyPDF offers a dedicated fill tool at signmypdf.io/fill that was built specifically for the use case HelloSign ignores. Here is how to use it from start to finish.
No account is required. Open the Fill tool in any browser on any device. There is no software to install, no sign-up form to complete, and no email to verify. The tool is ready immediately.
Drag your PDF onto the upload area or click to open the file picker. Your document loads directly in the browser. It is not sent to any server — processing happens entirely on your device, which matters when you are filling in sensitive information like a Social Security number, address, or tax ID.
Click anywhere on the document to place a text field. A cursor appears and you can type immediately. Reposition the text by dragging it to align with the blank line or box in the form. Resize the font to match the form's existing text. For multi-page documents, flip between pages and add text to every section that needs it.
For checkboxes, click to place a check character inside the box. For date fields, type the date in whatever format the form requires. There are no dropdown menus or special modes — everything is direct text placement, which keeps the tool fast and flexible regardless of how the form was originally designed.
After you have filled in all the text fields, add your signature to the document. Draw it with your mouse, trackpad, or finger on a touchscreen, or type your name in a cursive script font. Place it on the signature line and resize it to fit. This is the step HelloSign focuses on exclusively — SignMyPDF Fill does it as the final step of a complete form-filling workflow.
Click download. Your filled and signed PDF saves to your device instantly. The file is a standard PDF compatible with every document portal, email client, and filing system. Send it to your landlord, your accountant, your employer, or whoever requested the form.
The entire process from upload to download typically takes three to five minutes for a standard form, and there is no limit on how many forms you can fill per day.

Adobe Acrobat Reader is free for desktop users and can fill interactive PDF form fields well, but it requires downloading the application and does not work in a browser. On mobile it is functional but slower than a browser-based tool. DocHub is a solid browser-based option with Google Drive integration, but the free plan caps you at five documents per month — a limit that is easy to exceed if you are handling rental applications, tax forms, or employment paperwork regularly. PDFescape offers free browser-based PDF editing but the interface is dated and the free tier has file size restrictions.
SignMyPDF Fill is the only tool in this comparison that requires no account, imposes no monthly document cap, processes files locally in the browser for privacy, and works equally well on desktop and mobile. For most individuals filling out PDF forms, it is the most practical free option available.
What Real Users Say About Filling PDF Forms Free

> "I fill out medical intake forms, insurance claims, and HR documents constantly. HelloSign was useless for this. SignMyPDF Fill does everything — text fields, checkboxes, dates, signature — in one tool, for free. It is the only PDF tool I recommend to anyone." — Sarah M., Nashville, TN
Frequently Asked Questions
Why can't HelloSign fill PDF form fields?
HelloSign (Dropbox Sign) was designed as a signature-collection and workflow tool, not a PDF editor. Its core purpose is to send documents to people for signature and track whether they have signed. Filling in text fields, typing into blank lines, and completing form content are not part of that product design. For filling PDF forms you need a tool built for that purpose, such as SignMyPDF Fill at signmypdf.io/fill.
Can I fill out a PDF form and sign it in the same tool?
Yes. SignMyPDF Fill at signmypdf.io/fill handles both steps. After you have typed all the information into the form fields, you can add a drawn or typed signature before downloading the completed document. There is no need to use separate tools for filling and signing.
Do I need an account to fill out a PDF form with SignMyPDF?
No. You can fill and sign any PDF form at signmypdf.io/fill without registering or logging in. Upload your PDF, fill it in, add your signature, download the completed file. The entire process happens in your browser with no account required.
Is it safe to fill in sensitive forms like W-9s or medical forms online?
With SignMyPDF Fill, yes. The tool processes your document entirely within your browser. Your file is never uploaded to any server, and your personal information — including SSNs, addresses, tax IDs, and medical details — stays on your device throughout the process. This local processing model is more private than cloud-based tools that send your documents to remote servers for processing.
What types of PDF forms can I fill out with SignMyPDF Fill?
Any PDF form that has blank fields, lines, boxes, or spaces for text. This includes tax forms (W-9, 1040, W-4), rental and lease applications, employment forms and job applications, medical and insurance documents, government forms, financial forms, and any other standard PDF document with fillable areas. The tool places text freely anywhere on the document, so it works even on forms that were not designed with interactive fields.
