Both let you design a reusable template, send data, and get back a generated file. Both render raw HTML, host the output, generate images from a URL you can put in an image tag, offer official SDKs in several languages, and integrate with Zapier, Make, n8n, and Pipedream.
APITemplate.io's image API starts from a saved template. It can also turn raw HTML or a URL into a PNG or JPEG through its PDF endpoints, but viewport, selector, and device-scale options aren't documented there.
HTML/CSS to Image treats HTML, URLs, and templates as first-class inputs, with viewport, scale, selector, and timing controls on every render.
HTML/CSS to Image
Render HTML/CSS or URLs with viewport, scale, selector, timing, font, and other controls. Convenience options include google_fonts and a ScreenshotReady() signal for your page's JavaScript.
The same options apply whether you send HTML/CSS or a URL.
APITemplate.io
Generate images from saved templates, or render HTML or a URL through its PDF endpoints with PNG or JPEG output.
Viewport, selector, and device-scale options aren't documented for HTML-to-image.
Both have visual editors. HTML/CSS to Image uses one freeform canvas for every design, with optional flex and grid panels. APITemplate.io splits its editors by output: drag-and-drop for images, and a WYSIWYG or code editor for PDFs.
APITemplate.io's direct URLs put a template image straight into an image tag or og:image. They authenticate with a static auth code in the URL, which you can limit with a quota and an expiration.
HTML/CSS to Image's template URLs are signed instead, so each request is protected without a reusable code sitting in your page.
HTML/CSS to Image
Signed template URLs generate images on first access, with variable values in the URL. Put one directly in an image tag, email, or og:image without a separate image-creation API call.
Available on Free and paid plans. Signing keeps your API key out of public pages.
APITemplate.io
Direct URLs generate template images in an image tag, authenticated with a static auth code rather than a signature.
Auth codes can have a quota and an expiration. Images regenerate only when the parameters or template change.
PDFs are its core. Paper sizes, margins, custom headers and footers, @page CSS, and merging PDFs are all in the API, along with experimental ZUGFeRD and Factur-X e-invoices. A multi-page PDF counts as one credit.
Asynchronous generation calls your webhook when a file is ready, with three retries, and regional endpoints in Singapore, Frankfurt, US-East, and Sydney keep processing and storage in the region you call.
HTML/CSS to Image
The normal create request returns an image ID and URL. Rendering happens when that URL is requested, so the create response does not confirm render completion.
HTML/CSS to Image has no built-in render-completion webhook. If your application needs a background job and callback, implement that orchestration yourself. Custom-storage-only output uses an authenticated PUT to the returned store URL.
APITemplate.io
Generate asynchronously and receive a webhook when the file is ready, with three retries.
HTML/CSS to Image has no per-minute or concurrency limits on creating and rendering images. APITemplate.io allows 100 requests every 10 seconds per IP and 100 concurrent synchronous PDF requests per account. Requests past those limits return HTTP 429.
HTML/CSS to Image
Send image creation and rendering requests in parallel, with no concurrency caps or per-second or per-minute rate limits.
Image credits and plan limits still apply.
APITemplate.io
100 requests per 10 seconds per IP, and 100 concurrent synchronous PDF requests per account.
Requests over the limit return HTTP 429.
