Thumbnails and previews

Generate low-resolution thumbnail images from PDF pages for navigation, previews, and document organization.

How we help


DOCUMENT ENGINE

Server-side PDF-to-image conversion via REST API

Convert PDF pages to PNG, JPEG, WebP, or TIFF through a REST API. Configure output resolution by width, height, or DPI, and convert page ranges in a single request. The API returns a ZIP archive containing all rendered pages.

Multiple output formats

Output to PNG, JPEG, WebP, or TIFF from a single API endpoint.


Resolution control

Set output dimensions by width, height, or DPI — the API preserves aspect ratio automatically.


Page range selection

Convert specific page ranges by setting start and end page indexes in the request.


Batch output

Convert multiple pages in a single request and receive all rendered images in a ZIP archive.

.NET SDK

The widest format support for PDF-to-image conversion

Convert PDF pages to PNG, JPG, TIFF, BMP, SVG, WebP, and more. Supports multipage TIFF output, configurable DPI, and TIFF compression schemes. Render individual pages or convert an entire document at once.

15+ output formats

Convert to PNG, JPG, TIFF, BMP, SVG, WebP, GIF, JBIG2, JP2, and more image formats.


Multipage TIFF

Convert an entire PDF document into a single multipage TIFF file with configurable compression.


Configurable DPI

Set rendering resolution in DPI for each conversion — default 200 DPI for standard output, 300 DPI for high-quality TIFFs.


SVG vector output

Export PDF pages as scalable vector graphics — no rasterization or DPI configuration needed.

WEB AND NODE.JS

Client-side and server-side rendering in JavaScript

Render PDF pages as images in the browser with the Web SDK, or on the server with Node.js. The Web SDK outputs PNG images, while Node.js supports both PNG and WebP output.

Browser-based rendering

Render PDF pages as PNG images in the browser. Set output width and the SDK maintains the correct aspect ratio.


Node.js server rendering

Render pages on the server with PNG or WebP output. The SDK returns image data, ready for file writing or streaming.


Annotation rendering

Both SDKs render annotations on top of the page content in the output image.

IOS AND ANDROID

Render PDF pages on mobile devices

Convert PDF pages to images on iOS and Android. Both platforms support asynchronous rendering to avoid blocking the main thread and provide built-in thumbnail generation for document previews.

Asynchronous rendering

Render pages without blocking the main thread. Both iOS and Android provide asynchronous rendering APIs that keep the UI responsive.


Thumbnail generation

Generate low-resolution thumbnails from PDF pages for navigation, identification, and document organization.


Built-in image caching

iOS includes a built-in image cache for rendered pages, avoiding redundant rendering of the same content.






Frequently asked questions

How do I convert a PDF to JPG programmatically?

With the .NET SDK, load the PDF, select a page, render it at your chosen DPI, and save as JPEG. With Document Engine, send a request to the REST API specifying JPEG as the output format. Both approaches process pages without manual intervention.

How do I convert a PDF to PNG in my app?

All six platforms support PNG output. The Web SDK renders a page and returns a PNG image URL. Node.js renders pages and returns image data for file writing. The .NET SDK and Document Engine also support PNG with configurable DPI.

Can I convert a PDF to a multipage TIFF file?

Yes. The .NET SDK converts an entire PDF document into a single multipage TIFF file with configurable compression schemes. Document Engine also supports TIFF output for page ranges via the REST API.

What image formats can I convert a PDF to?

The .NET SDK supports the widest range: PNG, JPG, TIFF (including multipage), BMP, SVG, WebP, GIF, JBIG2, JP2, and more. Document Engine supports PNG, JPEG, WebP, and TIFF. Web and Node.js SDKs support PNG, with Node.js also supporting WebP.

How do I control the resolution of PDF-to-image conversion?

Resolution depends on the platform. The .NET SDK uses a DPI setting (default 200 DPI). Document Engine accepts width, height, or DPI parameters — all mutually exclusive, with aspect ratio preserved automatically. Web and Node.js use width-based rendering.

Can I generate PDF page thumbnails on mobile?

Yes. Both iOS and Android SDKs support thumbnail generation by rendering pages at reduced dimensions. Both platforms provide asynchronous rendering to avoid blocking the main thread, and iOS includes built-in image caching.

How do I convert PDF to images on the server?

Document Engine provides a REST API that accepts a PDF and returns rendered pages as a ZIP archive. Alternatively, the .NET SDK and Node.js SDK run server-side without GUI dependencies.

Does the SDK render annotations in the output image?

Yes. The Web SDK and Node.js SDK render annotations over the page background in the output image. The .NET SDK renders the page content as it appears, and Document Engine processes the full page including visible annotations.

PDF-to-image converter SDK

What’s a PDF-to-image SDK?

A PDF-to-image SDK lets developers programmatically render PDF pages as image files — PNG, JPG, TIFF, or other formats. Nutrient provides PDF-to-image conversion across six platforms, from server-side REST APIs to browser-based rendering and mobile SDKs.

  • Renders PDF pages to PNG, JPG, TIFF, WebP, SVG, and more.
  • Configurable resolution via DPI, width, or height settings.
  • Supports multipage TIFF output from entire documents.
  • Available on server, desktop, browser, and mobile platforms.
How do I choose a PDF-to-image converter SDK?

When selecting a PDF-to-image SDK, consider your deployment environment, the output formats you need, and whether you require batch processing or single-page rendering.

  • Output formats — The .NET SDK supports 15+ formats, including multipage TIFF and SVG. Document Engine supports PNG, JPEG, WebP, and TIFF.
  • Resolution control — Look for configurable DPI or dimension-based rendering to match your quality requirements.
  • Batch processing — Document Engine converts page ranges in a single API call. The .NET SDK can iterate pages in a loop.
  • Deployment model — REST API for server pipelines, desktop SDK for local processing, browser SDK for client-side rendering, mobile SDK for on-device thumbnails.
When should I use a PDF-to-PNG SDK vs. a PDF-to-JPG SDK?

PNG is lossless and preserves sharp text and line art — ideal for documents, diagrams, and archiving. JPG uses lossy compression for smaller file sizes — better for photo-heavy pages or when file size matters more than pixel-perfect accuracy. The .NET SDK and Document Engine support both formats, so you can choose per use case.

What are the benefits of Nutrient’s PDF-to-image conversion?

Nutrient provides PDF-to-image conversion across six platforms, so you can render pages wherever your application runs.

  • Six platforms — Document Engine, .NET, Web, Node.js, iOS, and Android.
  • Format breadth — From PNG and JPG to multipage TIFF, SVG, WebP, and 10+ additional formats in the .NET SDK.
  • Resolution control — Configurable DPI, width, and height settings for precise output quality.
  • Enterprise-proven — Trusted by Lufthansa, Disney, Autodesk, UBS, Dropbox, and IBM.
What is multipage TIFF and when should I use a PDF-to-TIFF SDK?

Multipage TIFF stores all pages of a document in a single image file. It’s widely used in document imaging, scanning workflows, and archiving systems. The .NET SDK converts an entire PDF into a multipage TIFF with configurable compression, while Document Engine supports TIFF output for page ranges via REST API.
