RUNS ON

Windows, Linux and macOS, on a host or in a container, wherever the .NET, Java or Python runtime the build targets is supported. No Microsoft Office installation on the machine that runs it.

Prefer not to host it yourself? The same work is available as a hosted REST API through Aspose.Slides Cloud.

  • 187 / 80

    Shape types and chart types the API creates, each a real object that PowerPoint still recognises and lets a person edit after the file is written.

  • 12 → 12

    Presentation formats read and written, including the pre-2007 binary .ppt container and OpenDocument .odp, plus 9 further export targets.

  • Monthly

    A new version of Aspose.Slides for .NET every month since December 2020. The NuGet version list dates each one.

  • 0

    Microsoft Office installs, GDI dependencies and X displays needed. A small Linux container is enough.

All products, side by side

Same object model everywhere. The differences that matter are the runtime and what each build adds on top. The last five rows are not libraries you write code against — two are the .NET package under another name, three are integrations for an existing server product.

What people use it for

Fifteen jobs, one page each. Twelve of them link to per-platform pages, each leading to code samples. Splitting, comparison and signatures offer a free online app instead.

Conversion Convert between PPT, PPTX, PDF, HTML, POTX, POTM and ODP. Merger Merge PowerPoint and OpenDocument presentations into one file. Splitter Split PPT, PPTX and ODP presentations into separate files. Parser Extract text, images, audio and video from a presentation. Viewer Open presentations and export them for viewing. Watermark Add text and image watermarks to PPT, PPTX and ODP. Protect Password-protect PPT, PPTX and ODP presentations. Unlock Remove password protection from PPT, PPTX and ODP. Redaction Find and redact text in PPT, PPTX and ODP presentations. Comparison Compare presentations in PPT, PPS, PPTX, POTX, PPSX, PPTM and ODP. Chart Create and edit charts in PPT and PPTX presentations. Metadata View and edit presentation document properties. Search Find text in PPT, PPTX and ODP presentations. Signature Add drawing, text or image signatures, and sign PPTX digitally. Annotation Remove comments and annotations from PowerPoint files.

Build a presentation from content you already have

Most of the presentation work people automate runs into a deck rather than out of one: pulling HTML, images, PDF pages or database rows onto slides. Aspose.Slides reads HTML markup straight into a text frame, keeping the headings, bold runs and lists it finds.

That is the whole program: no PowerPoint, no headless Office, no template file to keep in step. The same call takes markup a reporting job or a content system already produces, so an existing HTML report becomes a deck on a schedule instead of by hand.

HTML → PPTXPYTHON
import aspose.slides as slides

html = "<h1>Quarterly review</h1><p>Revenue up <b>18%</b> on the quarter.</p>"

with slides.Presentation() as presentation:
    shape = presentation.slides[0].shapes.add_auto_shape(
        slides.ShapeType.RECTANGLE, 0, 0, 720, 540)
    shape.fill_format.fill_type = slides.FillType.SOLID
    shape.fill_format.solid_fill_color.scheme_color = slides.SchemeColor.TEXT2
    shape.line_format.fill_format.fill_type = slides.FillType.NO_FILL
    frame = shape.text_frame
    frame.paragraphs.clear()
    frame.paragraphs.add_from_html(html)
    for paragraph in frame.paragraphs:
        paragraph.paragraph_format.alignment = slides.TextAlignment.CENTER
    presentation.save("quarterly.pptx", slides.export.SaveFormat.PPTX)
The slide this program writes, rendered by Aspose.Slides for Python via .NET 26.9.0 under a licence. The free trial writes the same file with an evaluation watermark on every slide.
Slide 1 of quarterly.pptx: a dark blue slide holding the heading Quarterly review and the line Revenue up 18 per cent on the quarter, with the figure in bold.

The conversions people come here for

Every conversion, by platform

Every row below has its own page with a runnable sample: eleven conversions and one merge, the ones readers of this site open most, with a row per language where more than one is popular. Eight platforms list every conversion they support on their own conversion page.

Capabilities, one line each

Everything here is supported. Where a grey note follows, the capability is delivered through a separate product or comes with a stated limit. Aspose.Slides also builds what a deck is made of, with a Python via .NET guide for each: slide masters and layouts · tables · speaker notes · SmartArt · animation.

Start with the trial, license when you ship

The trial is the full API, so you can test the formats you actually care about before you talk to anyone. In evaluation mode the library reads only the first five characters of any text, followed by a notice; its text extractor returns none of the presentation’s text; and saving adds an evaluation watermark to every slide. A temporary licence lifts all three for 30 days.

In use

There would be no hesitation in recommending Aspose.Slides (or any of the other APIs) for both small and larger technical requirements. It will save you a world of time, money and energy over building it for yourself.

It was worth the money with regards to purchase: it would have been nowhere near as fast without these products.

Oracle case study

The product worked as advertised, the documentation was easy to follow, and the support forums were all the help we needed. The final solution that we deployed has exceeded our initial expectations by a great deal.
