Need help?ODP to Image: One File per Slide, at the Resolution You Choose
.odp is an OpenDocument Presentation — the deck format LibreOffice Impress and Apache OpenOffice Impress save, and the format PowerPoint and Google Slides export when you ask for OpenDocument. It belongs to the OASIS OpenDocument family whose 1.2 revision was standardised as ISO/IEC 26300 and whose 1.3 revision became an OASIS Standard in April 2021. This page turns that deck into pictures: our servers render the presentation with LibreOffice, rasterize every slide at the DPI you pick, and hand back one image file per slide in whichever format you select. It is the right tool for embedding slides in a document, posting them to a platform that will not accept a deck, or archiving a talk as flat images.
How to Convert ODP to Image
- Upload Your ODP File: Drag the
.odponto the page or click "+ Add Files" to browse. A whole deck is a single upload — you do not need to split it first. - Pick the Image File Extension: Open Advanced Options and choose from the Image File Extension list: PNG, JPG, JPEG, WEBP, TIF, TIFF, BMP, GIF, AVIF, HEIC, HEIF, JFIF, PPM, EPS, ICO and APNG. Nothing is preselected here, so choose deliberately — PNG for slides with text and flat colour, JPG when file size matters more than crisp edges.
- Set Conversion Quality and Image Transparency: Conversion Quality is the render DPI, and it is the setting that decides how many pixels each slide gets — 72, 96, 150, 200, 300 (the default), 400, 600 or 1200 DPI. Image Transparency sets the colour rendered behind the slide and opens on White. Image Compression (Quality Preset, or Specific file size) and Image resolution are available if you need to trim the result afterwards.
- Convert and Download: Click "Convert". Every slide comes back as its own file, downloadable individually or as one zip. Files are uploaded over an encrypted connection, processed on our servers and deleted automatically after a few hours — no sign-up, no watermark.
How Many Pixels Each Slide Gets
Conversion Quality is a true render DPI, not a vague quality label: the slide is drawn at that density, so the pixel size follows directly from the slide's physical dimensions. LibreOffice Impress's default widescreen slide is 28 x 15.75 cm (11.02 x 6.20 in), which works out like this:
| Conversion Quality | Approx. pixels per slide (16:9 Impress default) | Sensible for |
|---|---|---|
| 72 DPI | 794 x 446 | Quick previews and thumbnails |
| 96 DPI | 1058 x 595 | Screen-sized inline images |
| 150 DPI | 1654 x 930 | Web pages, email, drafts |
| 200 DPI | 2205 x 1240 | Office documents that will be printed casually |
| 300 DPI (default) | 3307 x 1860 | Print-quality output — the safe general choice |
| 400 DPI | 4409 x 2480 | Slides carrying small text that must stay readable |
| 600 DPI | 6614 x 3720 | Archival masters |
| 1200 DPI | 13228 x 7441 | Fine-art reproduction; very large files |
A 4:3 deck (25.4 x 19.05 cm) produces different numbers on the same scale, and a custom slide size produces its own. In our testing, a three-slide 16:9 deck converted at the default 300 DPI returned three separate files measuring 3307 x 1860 pixels each, and the whole job finished in about 20 seconds.
Which Output Format for Slides?
| Format | Compression | Best for | Watch out for |
|---|---|---|---|
| PNG | Lossless container; our default preset runs a palette optimiser | Slides with text, charts, flat colour and screenshots | For a true-colour lossless PNG, set Quality Preset to "Highest" |
| JPG / JPEG | Lossy | Photo-heavy slides, or when the file size budget is tight | Blocking and ringing along text edges, especially at lower quality |
| WEBP | Lossy or lossless | Web publishing where you control the audience's browsers | Older desktop software may not open it |
| TIF / TIFF | Selectable | Print and archival hand-offs | Print shops usually want a lossless scheme such as LZW |
| AVIF / HEIC / HEIF | Lossy, modern | Smallest files at a given visual quality | Uneven support outside recent browsers and Apple software |
| GIF | Lossy palette, 256 colours | Simple diagrams and flat-colour slides only | Gradients and photographs will band badly |
| BMP / PPM | Uncompressed | Pixel-exact hand-offs into other tooling | Very large files |
| EPS | Raster embedded in PostScript | Legacy print workflows that demand EPS | The slide is embedded as pixels, not vectorised, and the files are large |
| ICO | Palette / PNG | Making an icon out of a slide, which is rarely what you want | The size list caps what is practical for a landscape image |
What Does and Doesn't Survive the Conversion
Rendering flattens the deck, so plan for what is lost. Text stops being text: it becomes pixels, so it is no longer selectable, searchable, spell-checkable or editable, and screen readers cannot read it. Slide transitions, object animations, embedded audio and video, and hyperlinks all disappear — a still image cannot express them, and only the final on-screen state of each slide is drawn. Speaker notes are not rendered, because they are not part of the slide surface. Fonts are resolved on our servers, so a deck that depends on a typeface installed only on your own machine can reflow; if exact letterforms matter, embed the fonts in the .odp before uploading, or export from Impress with the fonts embedded. If you need the deck to stay searchable and selectable, convert to ODP to PDF instead — that keeps the text as text.
Frequently Asked Questions
Does each slide become a separate image file?
Yes. The deck is rendered page by page and each slide is written as its own file, so a ten-slide presentation returns ten images. They can be downloaded one at a time or as a single zip. In our testing a three-slide deck produced exactly three files, one per slide, all at the same pixel size.
What DPI should I choose for slides?
300 DPI, the default, is right for most work — it prints cleanly and stays legible when zoomed. Drop to 150 DPI if the images are only ever going on a web page or into an email, since the files are roughly a quarter of the size. Go to 400 or 600 DPI when slides carry small footnote-sized text that has to stay readable, and reserve 1200 DPI for reproduction work: at that density a single 16:9 slide is over 13,000 pixels wide and the files get very large very quickly.
Will the text on my slides still be editable or selectable?
No. Every output on this page is a raster image, so text becomes pixels the moment the slide is rendered — no selecting, no searching, no copy and paste, and no screen-reader access. That is a deliberate trade for a picture you can drop anywhere. When you need the words to remain words, convert the deck to PDF instead and keep the .odp as your editable master.
What happens to animations, transitions and embedded video?
They are dropped, because a still image has no way to express them. Each slide is rendered in its final on-screen state, so an object that appears on a click will be visible in the image, and a video placed on a slide is drawn as its poster area rather than playing. If your deck depends on motion, export it as a video from Impress rather than converting it to images.
Why does my slide have a white background where I expected transparency?
Because the Image Transparency control opens on White, so the slide is composited onto a white backdrop before it is encoded. That is the sensible default — most slide masters assume an opaque page — and it also keeps output consistent for formats that cannot store an alpha channel at all, such as JPG and BMP. Change the colour in that dropdown if you want a different backdrop behind the rendered slides.
I picked APNG and got ordinary-looking still images. Is that right?
Yes. APNG is an animated format, but there is nothing here to animate: each slide is rendered independently, so a slide becomes a single frame, and a single-frame APNG collapses to a plain static PNG with no animation chunk. You still get one file per slide, not one animation of the deck. If you want the deck as a moving file, export a video from Impress; if you want ordinary stills, choose PNG or JPG.
Is PNG from this page truly lossless?
Not at the default setting. Our PNG output runs a palette optimiser at the standard quality presets, which quantises colours to shrink the file — visually excellent for slides, but not bit-for-bit lossless. Set Quality Preset to "Highest" if you need true-colour lossless PNG, for example when the slides will be re-edited or colour-matched later. For everyday sharing the default is the better trade.
How are my presentations handled, and what opens an .odp in the first place?
An .odp is opened natively by LibreOffice Impress and Apache OpenOffice Impress, and recent versions of Microsoft PowerPoint and Google Slides import it too. When you convert here, the file is uploaded over an encrypted connection, rendered and rasterized on our servers, then deleted automatically a few hours later along with the images it produced — nothing is shared, published or reused, and no watermark is applied. Single-format targets are available too, such as ODP to JPG and ODP to PNG, and the ODP converter hub lists the rest.
