HTML to Image renders images and PDFs from raw HTML, URLs or named templates, with no template caps on any plan. APITemplate.io answers with template editors and deeper PDF page control.
Disclosure: we built HTML to Image. We've kept this comparison honest because the alternative is search results full of low-effort listicles.

Stay with APITemplate.io when template management and PDF page control are the point. Its drag-and-drop plus HTML editors let less technical colleagues own the designs, four regional endpoints help with latency and data residency, and its PDFs carry headers, footers, page numbering and page-size options that our A4-only output does not. Report-style documents with running heads belong there.
Switch to HTML to Image when you want the render without the template-management layer. A specific scenario: your app generates OG images for every published page, social cards for a newsletter and invoices that ship as both a PNG and a PDF attachment. On APITemplate.io each design is a stored template counted against your plan's cap, built in its editor first. On HTML to Image you either call one of the 25 named templates or post your own HTML straight to the API, from $9 a month instead of $35, and the same request returns a PDF when you add one format parameter.
Raw HTML straight to image. Send markup, get a PNG, no stored template required. APITemplate.io supports raw HTML for PDFs but its image pipeline runs through templates you create and manage in its editors first. If your HTML is generated per-request from live data, the direct endpoint removes a whole layer of template administration.
No template caps and lower image pricing. All 25 templates are available on every plan, and our pricing is cheaper for images at every published tier: $25 versus $35 at 1,500 renders, $60 versus $89 at 9,000, and $120 versus $179 at 20,000. APITemplate.io caps stored templates at 3, 15 and 150 as you move up its ladder.
URL screenshots to image on the same key. APITemplate.io converts URLs to PDF but does not offer webpage screenshots as images. If your product needs page captures alongside generated graphics, HTML to Image keeps both on one bill.
PDF page control. Both products convert templates, raw HTML and live URLs to PDF, but APITemplate.io adds custom headers, footers, page numbers and page sizes, plus dedicated PDF-only plans from $19 a month. HTML to Image PDFs are A4 portrait with automatic pagination and no running-head controls, which covers invoices and receipts but not report-style documents with numbered pages.
Template editors and a bigger integration surface. A drag-and-drop WYSIWYG editor and an HTML/CSS editor with live preview let non-developers own the designs, and native Zapier, Make, n8n, Airtable and Bubble integrations plus SDKs for six languages cover no-code and low-code teams. HTML to Image is HTTP-first with official PHP and Laravel packages.
Regional endpoints. US, EU, Singapore and Australia regions help both latency and data-residency requirements. HTML to Image renders from one region with CDN delivery, which is fine for most workloads but weaker on residency compliance.
# APITemplate.io (template render)
curl -X POST "https://rest.apitemplate.io/v2/create-image?template_id=79667b2b1876e347" \
-H 'X-API-KEY: your-api-key' \
-H 'Content-Type: application/json' \
-d '{"overrides":[{"name":"text_1","text":"Hello"}]}'# HTML to Image (template render)
curl -X POST https://app.html2img.com/api/v1/templates/open-graph-image \

-d '{"title":"Hello","subtitle":"From Northwind Studio"}'
Three concrete differences. Templates are selected by URL slug (/templates/{slug}) instead of a template_id query parameter pointing at a template you built in the editor. Inputs are flat named JSON keys rather than an overrides array of element name and property pairs. And the response is a JSON envelope with a single url for the PNG on our CDN, where APITemplate.io returns separate download_url and download_url_png fields. Confirm the designs you need exist in the templates gallery before migrating.
See the API parameters reference for the full request and response shape.
There is no crossover: HTML to Image is cheaper at every published tier. At 1,500 renders a month it is $25 on our 3,000 plan versus $35 on Starter. At 9,000 it is $60 versus $89. At 20,000 it is $120 versus $179. Annual billing narrows the gap ($29, $69 and $139 respectively) without closing it. PDFs no longer change the calculus either: both services render images and PDFs from a single allowance, and a PDF costs one credit here exactly like a PNG. What APITemplate.io's PDF pricing buys is page control, not volume.
Yes. Both products render PDFs from templates, raw HTML or live URLs. On HTML to Image you add format: "pdf" to any request and the response URL points at a vector A4 document with selectable text, for the same one credit as an image. The difference is page control: APITemplate.io adds headers, footers, page numbers and page sizes, plus PDF-only plans from $19 a month, where our output is A4 portrait with automatic pagination.
No. All 25 named templates are available on every plan, including the free tier. APITemplate.io caps stored templates per plan: 3 on the free tier, 15 on Starter and 150 on Standard, with unlimited only on Enterprise at $179 a month. If you generate many design variants, that cap is the number to check first.
Yes, that is the core of the product. The HTML endpoint takes raw markup with full CSS and JavaScript execution and returns a PNG. On APITemplate.io, images render from templates you build in its drag-and-drop or HTML editors first; raw HTML straight to image in a single API call is not the workflow, though raw HTML to PDF is supported.
No. APITemplate.io offers four regional endpoints (US, EU, Singapore and Australia), which helps with latency and data residency requirements. HTML to Image renders from a single region with global delivery via Cloudflare. If data residency is a compliance requirement, APITemplate.io has the stronger answer today.
The free tier covers 25 renders a month with no credit card. Try the API against your real data before deciding.
No caps, no editor step. Twenty-five pre-built designs available on every plan, including free. JSON in, PNG out, single API call.
