Supports: ODP
This walkthrough is for anyone who needs an OpenDocument Presentation (the .odp format used by LibreOffice Impress, Apache OpenOffice, and Google Slides exports) as flat picture files — slide thumbnails, previews for a web page, or images for a platform that only accepts photos. Each slide of the ODP becomes its own JPG; a twelve-slide deck produces twelve images. The output is a picture, not an editable slide, so keep your original .odp if you still need to present or edit it.
.odp files and convert them with the same settings.Two controls decide whether your slides look crisp or fuzzy, and how large the files end up.
Conversion Quality (DPI) is the main lever. DPI sets the rendering resolution, so a higher number means more pixels per slide — sharper, but larger. The page offers presets from 72 up to 1200 DPI:
Image Compression is the second lever. The Quality Preset defaults to "Very High (Recommended)", which keeps JPEG's lossy compression light so slide text and logos stay clean. Lower it a notch only when you need a smaller file and can accept softer edges. If you want to hit a specific file size instead of guessing, the converter also exposes a target-size control under the resolution options.
The Image resolution control caps or scales the pixel dimensions independently of DPI — keep the original, choose a preset, or type an exact width/height when each image must fit a fixed slot (an email banner, a CMS thumbnail).
JPG is the wrong target when you need to keep working with the content. The text in every output image is rasterized — it becomes pixels, so it is not selectable, searchable, or editable, and you cannot fix a typo in the picture. If you need a slide deck that stays selectable, printable, and is one file rather than a folder of images, convert to ODP to PDF instead. If you need the sharpest possible text or a transparent background, use the lossless ODP to PNG converter. For a password-protected or corrupted presentation, remove the protection in LibreOffice Impress and re-save before uploading.
Yes. The converter renders every slide in the presentation to its own JPG image, so a twelve-slide deck produces twelve files. When there is more than one slide, the images are delivered together as a ZIP archive — download it and unzip to get each slide as an individual picture.
No. The JPG is a flat raster image — a picture of the slide. Every word, bullet, and table is painted as pixels, so none of it can be selected, copied, or searched, and you cannot edit it. Keep your original .odp for editing, and if you need selectable text in the exported file, convert to ODP to PDF, which keeps text as real text.
They are not carried over. A JPG holds a single static frame, so build-in animations, slide transitions, and any embedded audio or video are dropped. Each image shows its slide in the final state, as if every animation had already played to the end.
Use JPG when you want the smallest files and the slides are mostly normal text and photos headed for the screen or social media. Use PNG when sharpness matters — slides with small fonts, fine tables, line art, screenshots, or a logo on a transparent background — because PNG is lossless and does not add edge artifacts. The tradeoff is size: a photo-heavy slide is usually smaller as JPG, but a text-heavy or graphic slide is cleaner as PNG.
Match the DPI to where the image is going. 96-150 DPI is fine for on-screen viewing and sharing and keeps files small; 300 DPI (the default here) is the print standard and the safe choice when you are not sure; 400 DPI or higher helps when slides have very small text or you plan to run OCR. Below about 96 DPI, slide text starts to look soft.
It depends on the slide size and the DPI you pick. In our testing, a standard 16:9 widescreen slide (10 × 5.63 in) at the default 300 DPI rendered to roughly 3,000 × 1,688 pixels — sharp enough to read comfortably and to print at a useful size. Halving the DPI to 150 roughly quarters both the pixel count and the file size.
