What This PowerPoint to PDF Converter Does

This converter transforms your Microsoft PowerPoint files — both the older PPT format (PowerPoint 97–2003) and the modern PPTX format (PowerPoint 2007 and later) — into fixed-layout PDF documents where each slide becomes a full-resolution PDF page. You can convert up to three files at once with a combined size of 15 MB. Multiple conversions are packaged automatically into a single ZIP download, with individual download links available for each file.

Conversion is handled server-side by LibreOffice, a battle-tested open-source rendering engine used across enterprise deployments worldwide. Slide backgrounds, colour themes, embedded images, vector shapes, tables and text all land in the PDF exactly where you placed them in your deck. Animations and transitions are captured in their final resting position — the state each element is in after all animations have completed on that slide. Embedded video clips are not carried into the PDF since PDFs are static by nature, but a static thumbnail frame is preserved in their place. Files are deleted from our servers immediately after download.

Tips for the Best Conversion Results

Frequently Asked Questions

Is this PowerPoint to PDF converter completely free?

Yes, completely free with no hidden conditions. There are no conversion limits, no watermarks added to your output PDFs, and no account or payment information required at any stage. You can convert as many files as you need, as often as you need, without any cap on daily or monthly usage. Convixy's tools are funded by advertising, not by paywalls or per-conversion fees.

The only constraints are technical ones designed to keep the service fast and reliable for everyone: a maximum of three files per upload session, a combined total upload size of 15 MB, and a 15 MB output PDF size limit per file. Presentations that exceed the output limit almost always contain embedded video clips or very high-resolution photographs — removing or compressing those before uploading resolves the issue in the vast majority of cases.

What PowerPoint file formats are supported — PPT and PPTX?

Both formats are fully supported. PPT is the legacy binary format used by PowerPoint 97 through 2003. It stores everything in a proprietary binary structure and is less compatible with non-Microsoft software, but remains common for older presentations and archival files. PPTX is the current Open XML format introduced with PowerPoint 2007, natively supported by Google Slides, Apple Keynote, LibreOffice Impress and all modern versions of PowerPoint. PPTX files are generally smaller, more portable and more reliable to open across platforms.

Both convert with the same accuracy and speed. If you have old PPT files you convert regularly, re-saving them as PPTX in PowerPoint first produces a more compact source file that uploads faster and renders more reliably. Presentations created in Google Slides or LibreOffice Impress and exported as PPTX are also supported, provided they use the .pptx file extension.

Does conversion preserve fonts, layouts, images and design exactly?

Yes, for the vast majority of presentations. Slide dimensions, text positioning, font weights, image placement and sizing, table borders and fills, shape colours and gradient backgrounds, and slide background images all carry over intact into the PDF. The conversion engine renders each slide at the page level, so the output matches the print layout of your presentation rather than re-flowing any content.

The one scenario where a visual difference can appear is custom or third-party fonts not installed on the conversion server. In that case, a closely matched substitute font is applied automatically. For most fonts this is invisible, but presentations with very tight custom typography or condensed typefaces may show minor spacing differences. The fix is to embed your fonts before uploading via File → Options → Save → Embed fonts in the file — this guarantees pixel-accurate output regardless of which fonts are available server-side.

What is the file size limit and why does PowerPoint to PDF sometimes fail?

The upload limit is 15 MB per file and 15 MB combined total. The output PDF is also capped at 15 MB — if a presentation would produce a PDF larger than this, conversion is stopped automatically and an error message describes the problem. The most common causes of oversized output are embedded video clips, very high-resolution photographs (particularly stock images pasted at original resolution), and large background images repeated across many slides.

The fastest fix is to compress images inside PowerPoint: click any image, open Picture Format → Compress Pictures, uncheck "Apply only to this picture", and choose Email (96 ppi). This reduces image-heavy decks by 60–80% in file size with no visible quality loss. For video clips, replace each one with a static thumbnail image and a URL or QR code — videos are not playable in PDFs regardless, so recipients lose nothing by this change. If conversion times out on a very complex deck, try splitting it into smaller sections and converting each part separately, then merging with our Merge PDF tool.

Can I convert multiple PowerPoint files at once?

Yes — up to 3 files at a time, with a combined total size of 15 MB across all files in the session. When you convert two or three files together, all the resulting PDFs are automatically bundled into a single ZIP download for convenience. Individual download links are also shown below the ZIP button so you can grab any specific file without downloading the entire archive.

To select multiple files, hold Ctrl (Windows) or Command (Mac) while clicking files in the file picker, or drag all the files together onto the upload area. If you need to convert more than three presentations, download the first batch and then upload the next set — there is no cooldown period between sessions. Once you have multiple PDFs, you can combine them into a single document using our Merge PDF tool, or extract specific slides from any of them with Split PDF.

How are animations and transitions handled in the PDF?

PDF is a static format and cannot contain interactive animations or slide transitions. When your presentation is converted, each slide is captured in its final state — the position every element is in after all animations on that slide have completed. If you have elements that fly in, fade in or appear on click, they will appear in the PDF as though all those animations have already finished.

This means objects that are hidden until an animation trigger are visible in the PDF from the start. Before converting, review each slide in Normal View to verify that all animated elements land in the right position and that nothing appears that you intended to reveal progressively. If you use "appear" animations to build a list point by point, consider whether you want each bullet visible from the start or whether you should create separate slides for each reveal stage before converting to PDF.

Are my presentations kept private and secure?

Yes. All file transfers happen over an encrypted HTTPS connection, so your presentation is protected in transit. Once your PDF is generated and ready for download, both the uploaded PowerPoint file and the converted PDF are automatically deleted from Convixy's servers — typically within the same browsing session and always within one hour of upload. No manual deletion is required on your part.

We do not read, index, analyse, share or retain the content of your presentations under any circumstances. No account is required, so there is no user profile for your files to be associated with, and no email address or personal information is collected. This tool is safe to use with confidential client decks, investor pitches, internal strategy presentations and any other sensitive content. If your privacy requirements are stricter, PowerPoint's built-in File → Export → Create PDF/XPS converts locally on your device without any upload.

Do I need Microsoft Office or PowerPoint installed?

No. Convixy runs entirely in your browser and conversion happens on our servers using LibreOffice. You do not need Microsoft 365, a PowerPoint licence, Adobe Acrobat or any other desktop application installed on your device. The tool works on every modern browser — Chrome, Firefox, Safari and Edge — across Windows, macOS, Linux, Android and iOS.

This makes it particularly useful when you receive a PPTX file on a device that does not have PowerPoint installed — on a Chromebook, a work computer without an Office licence, or a phone. Open the browser, upload the file, and download the PDF in seconds without any software dependency. The only thing you need is a working internet connection to upload the file.

Why does PowerPoint to PDF sometimes take longer than other converters?

Most presentations convert in under fifteen seconds. Conversion takes noticeably longer when a deck contains many slides with high-resolution photographs, large embedded diagrams, complex gradient fills applied to dozens of shapes, or SmartArt graphics that require intensive rendering. The progress bar and cycling status messages keep you informed while work is in progress — the longer states ("Still working…", "Nearly ready…") are normal for complex decks and do not indicate a problem.

PowerPoint conversion is inherently slower than Word or Excel conversion because each slide must be rendered as a full-page vector graphic, including all positioning, layering and transparency effects. This is also why the output PDF can be noticeably larger than the source PPTX — the PDF stores each slide as a complete rendered page rather than as structured XML instructions. Compressing images inside PowerPoint before uploading speeds up both upload and render time significantly, and reduces the final PDF size.

What can I do with the PDF after converting?

Once you have your PDF, Convixy has a full suite of tools to manage it further. To reduce the file size before emailing or uploading to a conference portal with size limits, use Compress PDF — it significantly reduces size with no visible quality loss on slides. To combine your converted deck with a speaker notes document, an agenda or a supporting report, use Merge PDF. To extract only specific slides — for instance pulling out an appendix or creating a shortened version of a long deck — use Split PDF.

You can also convert other Office formats in exactly the same way. Word to PDF converts DOC and DOCX files while preserving all text formatting, tables and images. Excel to PDF converts spreadsheets while preserving cell formatting, borders and embedded charts. All tools are free, require no account and delete your files immediately after download.
