Convert ODP to PDF

How it works

Tap the box (on a phone) or click it (on a computer) and pick your ODP file; you can select several presentations together, and each becomes a separate PDF. The tool opens the .odp package saved by LibreOffice or OpenOffice Impress inside your browser: it walks the slides (draw:page) in content.xml from first to last, collects each slide's title box, outline bullets, text boxes, tables and JPEG/PNG pictures, reads the slide size from styles.xml and writes one PDF page per slide. A concrete case: you built a 15-slide presentation in Impress on a school or council computer running Ubuntu with LibreOffice, the file reached your phone by email, and the phone cannot open an .odp. Save the attachment, tap the box on this page, pick the file from Files on an iPhone or from Downloads on Android, then press "Convert to PDF"; a 15-page PDF downloads in a few seconds. A 16:9 presentation gives 720 × 405 pt pages (10 × 5.63 in), a 4:3 presentation 720 × 540 pt (10 × 7.5 in); titles come out 20 pt bold, bullets 12 pt with a bullet mark, and nested bullets are indented. Switch the notes on only if you are the one presenting: with "Include notes" selected, each page gets a "Notes:" heading and the note text in 10 pt underneath; for an assignment or a file sent to a client, leave the option off. The honest limit: the layout in Impress is not kept. Boxes are taken in their order, not their position on the slide, and the content is written top to bottom as a flow; background, theme, transitions and animations are not in the PDF. The result line gives slides → pages, the number of embedded pictures, the page size and the notes status; if a picture that is not JPEG or PNG was skipped, the count is reported.

This tool is also known as odp to pdf, odp to pdf converter, convert odp to pdf, libreoffice impress to pdf, open odp file, odp file to pdf on phone.

What is ODP?

ODP (OpenDocument Presentation) is the format LibreOffice Impress and OpenOffice Impress save presentations in; it is the presentation member of the ISO 26300 OpenDocument family (.odt is the text member, .ods the spreadsheet). A file ending in .odp is really a compressed package: every slide is a draw:page element sitting in order inside content.xml, the slide size and master layout live in styles.xml, the pictures sit in a Pictures folder, and a small file called mimetype names the type. Each box on a slide carries a class (title, outline, notes); this tool reads that class to set the title in a larger size, the outline with bullet marks and, if you ask, the notes at the foot of the page. Phones, email previews and school or council upload portals do not open .odp, so the copy you share is turned into a PDF; a password-protected .odp and a .fodp saved as flat XML cannot be read here.

What is PDF?

PDF is the fixed-page format that makes a presentation look the same on every device: the page size, the place of every line and the font are written into the file, so the slides do not shift on a phone without Impress, on a projector laptop or on a printer. This tool takes the page size from the presentation's own layout: a 16:9 slide becomes a wide 720 × 405 pt landscape page (10 × 5.63 in), a 4:3 slide a squarer 720 × 540 pt page (10 × 7.5 in); Impress stores the slide size in centimetres and the tool converts it to points. A font with full accented-letter coverage is embedded in the PDF, so letters such as é, ñ or ü show correctly even when the recipient's device lacks that font, and the text stays selectable and searchable.

What is the difference between ODP and PPTX?

Both formats carry a presentation, and both are ZIP packages full of XML; the difference is which vocabulary the XML follows. PPTX is Office Open XML (ISO 29500), the native format of PowerPoint: each slide is a separate file under ppt/slides, and the order is read from a list in presentation.xml. ODP is OpenDocument (ISO 26300), the native format of Impress: all slides sit one after another in a single content.xml, and the slide size comes from the page layout in styles.xml. On Ubuntu and other Linux desktops, and on school computers that ship with LibreOffice, presentations are mostly saved as .odp; on Windows .pptx is the usual choice. PowerPoint can open an .odp and Impress can open a .pptx, but saving in the other format can change placeholder layouts, bullet settings and fonts, and phones usually show no preview of an .odp at all. To share a deck, making a PDF causes fewer problems than switching formats: the PowerPoint to PDF page handles .pptx, this page handles .odp; both use the same layout engine, so the output looks the same.

What is carried over and what is lost?

Carried over: the slide order and count (an empty slide becomes an empty page, so the page count stays equal to the slide count); the title placeholder (presentation:class="title") large and bold, the subtitle in a medium size, the outline box with bullet marks and indent levels; in a numbered list the number format (1., a), i.) is kept. Text inside text boxes and shapes arrives as plain text in document order; line breaks and tabs, tables (equal columns; the header row on a grey background), JPEG and PNG pictures placed in the presentation (the centimetre size from Impress is converted to points and scaled down if the page is too small) and, if you chose them, the speaker notes go in. The font is always Noto Sans; it is embedded for accented letters, and the font name in the presentation is ignored.

Lost: the layout. In Impress every box has an x/y position; in the PDF the boxes come one under another in order, two boxes side by side end up stacked, and a two-column layout becomes one column. Background, theme, header and footer, date and page number fields from the master page are not drawn; slide transitions, animations, charts, drawing objects, audio and video are skipped. SVG, GIF, WMF, EMF and TIFF pictures cannot be embedded; the result line says how many were skipped. A paragraph that is bold throughout stays bold, a few bold words come out plain; italic and colour are not carried over. If the look has to be identical, use Impress's own "File > Export as PDF" command; this tool is for reaching the content on a device that has no Impress.

Which setting for which situation?

Speaker notes: off by default, because a note is usually a reminder the presenter wrote for themselves and should not reach the other side; keep it off for an assignment, a client deck or an application file. Switch it on if you will present the deck yourself and want a paper copy: the note sits under its slide's page with a "Notes:" heading in 10 pt, and a slide without a note gets no such section. When the option is off and the presentation has notes, the result line says "N speaker note(s) present, not added because the option is off", so you know whether you forgot the notes without opening the file.

Font size: "Automatic" (20 pt titles, 12 pt body) reads well on screen and on a Letter or A4 printout. Pick "Large" for a handout you will give out, "Small" for a deck with many lines squeezed onto one slide; if the text still does not fit, the tool splits the page and the page count exceeds the slide count, which the result line shows. The page ratio needs no setting: the size in Impress's "Slide > Slide Properties" window (28 × 15.75 cm for Screen 16:9, 28 × 21 cm for Screen 4:3) is read from the file and scaled to a 720 pt width with a 0.5 in margin; if the size cannot be read, 16:9 is assumed. A password-protected .odp does not open; in Impress, untick "Save with password" in the "Save As" window and save again. Go to the PowerPoint to PDF page for a .pptx file and to the ODT to PDF page for an .odt.

Frequently asked questions

How do I convert an ODP file to PDF?

Tap the box and pick your .odp file, change the speaker notes and font size settings if you need to, and press "Convert to PDF"; the PDF downloads in a few seconds with one page per slide. There is nothing to install: no LibreOffice, OpenOffice or PowerPoint is needed, and it works on a phone. If you are on a computer with LibreOffice, Impress's "File > Export as PDF" command keeps the exact look of the slides; this page is for a device that has no Impress.

Is my file uploaded to a server?

No. The PDF writer and the font are downloaded to your browser along with the page; the code that opens the .odp package, walks the slides and writes the PDF runs on your device. The presentation itself, its name and its contents go to no address; once the page has loaded, the conversion finishes even if the internet drops. That is the point that matters for a thesis defence, a project not yet presented or a deck carrying company figures.

Does an ODP file open in PowerPoint?

It does: PowerPoint 2010 and later reads an .odp through "File > Open" and can save it as .pptx if you want. But crossing formats can break placeholder layouts, bullet marks, fonts and tables; if your aim is to send the deck to someone, making a PDF on this page brings fewer surprises than changing the format. Most phones and email previews do not open .odp at all, while every device opens a PDF.

Why does the slide layout not come out the same?

Because the tool carries the slide's content, not its picture. Impress draws each box at its x/y position on the slide; in the PDF the boxes are written one under another in order, two boxes side by side end up stacked, and the background and theme are not drawn at all. In return the text is selectable and searchable, the file is small, and the PDF can be made on a phone without Impress. If the look has to stay identical, use the PDF export built into Impress or PowerPoint.

Can I merge several presentations into one PDF?

Not on this page: when you pick several .odp files, each presentation downloads as its own PDF, because the ratios (16:9 and 4:3) may differ between decks and the pages = slides relation is kept per file. If you want a single file, feed the resulting PDFs to the merge PDF tool; the slide order is preserved inside each file.
