Fillable

What Fillable is

Fillable turns PDF paperwork into guided client flows and provides browser-based tools to fill, create, sign, merge, split, compress, convert, and OCR PDFs. Guided packs collect completed forms and requested documents through shareable links; clients can use a link without an account or app. The free plan includes one active pack and the form and official-form library. Teams can import PDFs, use field validation and conditional logic, and export as PDF or JSON. Its API can parse PDF fields and text into JSON or fill existing PDF form fields. Each API key allows 100 requests per calendar day, including authenticated calls that return errors. The API cannot create PDFs from HTML, convert file formats, or add fields to flat PDFs. Core PDF tools run in the browser; server-side conversions upload files and delete them after conversion. Fillable says API documents are processed in memory and not stored, content is not logged, and traffic uses HTTPS. Plans include Free, Pro at $9 a month, Team at $29 a month, and API at $49 a month.

Who it suits

Fillable may suit law, accounting, immigration, mortgage, healthcare, or real estate teams collecting forms and documents from clients. It also fits developers who need PDF field parsing or form filling through an API.

Limits

The free plan includes one active guided pack, everyday file sizes, a few conversions per day, a test API key with 100 requests per day, and an export footer. Each API key allows 100 requests per calendar day; authenticated calls count whether they succeed or return an error. The API does not create PDFs from HTML, convert file formats, or add fields to flat PDFs.

Getting started

1. Open Fillable on the web or use its API.
2. Use the free plan, which includes the form library and one active guided pack.
3. Import an existing PDF or choose a form template.

Verdict

Fillable combines PDF editing tools with guided collection links and an API for parsing or filling existing forms. The free tier is useful for a basic pack, while API usage has a daily request cap and defined limits.
