6 free alternatives to SimplePDF

PDF-API.io gives you a free monthly allowance built around document generation rather than editing: 1 user, 1 template, up to 100 PDFs per month, plus API and Zapier integration. The free plan also requires no credit card. Its main advantage is workflow readiness, since you can generate PDFs from an API and connect it to automation tools without leaving the free tier. It falls short on interactive editing in the browser, which SimplePDF is built around. Switch if your priority is generating PDFs from data, not letting end users edit a form-like PDF inside your app.

• Beats SimplePDF: API and Zapier integration included
• Falls short: Browser-based PDF editing for individuals
• Who should switch: Switch if you need template-driven PDF generation and automation more than in-browser editing.

CraftMyPDF's free tier includes 50 PDFs or images per month, 3 templates, REST API access, and integrations for Zapier, Make.com, and Bubble.io. That makes it useful for lightweight document automation and no-code workflows. Compared with SimplePDF, it is better when you want to generate PDFs from reusable templates and connect them into automations. It falls short on the editing experience, since the free tier is about creation from templates, not end-user PDF editing. Choose it if your workflow starts with data or templates and you need simple API-based output.

• Beats SimplePDF: REST API access plus workflow integrations
• Falls short: Direct browser-based PDF editing
• Who should switch: Switch if you want template-based PDF generation with automation hooks rather than a browser editor.

PDFMonkey's free plan gives you 20 documents per month, 1 day of document retention, fillable PDF forms, PDF password protection, and 1 team member. It is a better fit when you want browser-rendered PDF generation from HTML, CSS, JavaScript, and JSON, rather than an editor for end users. Its free tier is narrower on volume and is constrained by no external images, fonts, CSS, or JavaScript. But it does include form handling and security features that are useful for controlled document generation. Switch if you need template rendering and a small free allowance for internal document flows.

• Beats SimplePDF: Fillable PDF forms included
• Falls short: Free PDF editing for individuals
• Who should switch: Switch if your use case is controlled PDF generation with forms and light collaboration.

CustomJS includes 20 requests per day shared between JavaScript execution and PDF rendering, up to 3 forms, 500 form responses per month, 5 hosted pages, 1 custom domain, and email support. It is free for teams that want to combine forms, custom logic, and PDF generation in one place. Relative to SimplePDF, it is stronger when you need hosted pages and form workflows instead of just editing a PDF in the browser. The tradeoff is that its free tier is quota-driven and branding-heavy, so it is not as clean a fit for simple standalone PDF editing. Switch if you need a small app-like workflow around forms and PDFs.

• Beats SimplePDF: Hosted pages and form workflows included
• Falls short: No-ads browser-based editing for individuals
• Who should switch: Switch if you need custom logic, hosted pages, and form intake around PDFs.

PDFBolt's free tier includes 100 PDF documents per month, 20 requests per minute, 1 concurrent request, 1 reusable template, 1 AI template generation, all customization options, and no credit card required. That makes it a strong fit for developers who want API-based PDF rendering with a small but practical free allowance. Compared with SimplePDF, it wins on API-oriented generation, request control, and template customization. It falls short on interactive editing, since the product is centered on rendering PDFs from HTML, URLs, or templates. Switch if you want the closest thing to a low-volume PDF generation service with room to test production workflows.

• Beats SimplePDF: All customization options and API-style PDF generation
• Falls short: Interactive browser-based editing
• Who should switch: Switch if you need API-first PDF rendering with rate limits and templates.

Fillout's free tier is the most generous by headroom: unlimited forms, unlimited seats, and up to 1,000 responses per month, plus embedding, workflows, PDF generation, conditional logic, REST API access, integrations, and file uploads. It is built for form collection and workflow intake rather than PDF editing, but it gives a lot of room before a team has to pay. Compared with SimplePDF, it is much better if your real need is collecting responses and routing them through a process. It falls short because it is not a PDF editor. Switch if you need a free front door for forms and workflows instead of document editing.

• Beats SimplePDF: Unlimited forms and unlimited seats
• Falls short: Browser-based PDF editing for individuals
• Who should switch: Switch if your main job is collecting responses and running intake workflows.
