Merge ODG to PDF

How to Merge ODG Drawings to PDF Online

1. Upload Your ODG Files: Drag and drop multiple .odg files, or click "+ Add Files" to select them. Each drawing becomes one page in the combined PDF, in the order you upload — drag thumbnails to rearrange.
2. Choose Combine Mode and Page Setup: Under "Combine?" pick "Single PDF" (one merged file) or "Individual PDFs" (one PDF per drawing, returned as a zip). Set "Paper size" (A4 default, or LETTER, A3, LEGAL, TABLOID, LEDGER, ARCH A/B, ISO B4/B5, or "Original" to match the drawing's own page size) and "Page layout" (Portrait or Landscape — Landscape suits wide flowcharts and floor plans).
3. Tune Image Placement, Margin, and Quality (Optional): "Image placement" — Cover fills the page edge-to-edge (may crop), Contained fits inside the margin (default). "Image alignment" — Top, Center (default), or Bottom. "Margin" — No margin (0"), Narrow (0.5", default), Moderate (0.75×1"), Normal (1"), or Large (2×1"). "Image Compression" — drag the Quality slider (default 75); raise to 90+ for prepress, drop to 50 for tiny email files. "Compression Type" — Screen (smallest, default), Ebook, Default, Prepress, or Printer (largest, sharpest). "Image Transparency" — leave Unchanged or set to Removed if a viewer is rendering transparent areas as black.
4. Merge and Download: Click "Merge" — files are processed in your browser session and the combined PDF downloads when ready. No sign-up, no watermark, no LibreOffice install required.

Why Merge ODG to PDF?

ODG is the OpenDocument Drawing format defined by the OASIS OpenDocument specification (ISO/IEC 26300, first published as an international standard in November 2006, with ODF 1.4 ratified by OASIS in December 2025). It is the native vector format for LibreOffice Draw and Apache OpenOffice Draw, and stores diagrams, flowcharts, floor plans, network topologies, and technical illustrations as XML inside a zip container. The trouble: anyone you send an .odg to needs LibreOffice or OpenOffice installed to open it — Microsoft Office, Apple Preview, Google Drive's web viewer, and most browsers will not render it natively. Merging to PDF solves that and gives you one document instead of N.

• Hand a client a deliverable they can actually open — PDF opens in every browser, every email client preview pane, every phone, and every print shop. ODG opens in LibreOffice Draw, Apache OpenOffice Draw, and a handful of converters. Architects, engineers, and consultants who draft in Draw routinely export to PDF for delivery.
• Combine multi-page drawing sets into one file — Network diagrams, electrical layouts, and process flowcharts are often split across many .odg files for easier editing. A single 12-page PDF is far less error-prone than emailing 12 attachments labelled floor1.odg, floor2.odg, floor3.odg.
• Avoid the LibreOffice "single page only" export gotcha — LibreOffice's "Export Directly as PDF" toolbar button exports only the currently selected page when nothing is multi-selected, a behaviour reported on Ask LibreOffice. Uploading the source files here sidesteps that — every file you add gets a page.
• Print to A3, ARCH B, or Tabloid without leaving the browser — Floor plans and large schematics need bigger paper. Pick A3 (297×420 mm), Tabloid (11×17 in), Ledger, or ARCH A/B in the Paper size dropdown without touching LibreOffice's "Slide Properties" dialog.
• Bypass the LibreOffice install requirement on locked-down machines — School, library, government, and enterprise machines that block software installs can still merge ODG to PDF through the browser.
• Archive design iterations — PDF/anything-readable beats .odg for long-term archives because the rendering layer is frozen. ODF 1.0 files from 2005 still open in modern Draw, but PDF is more portable for non-technical recipients.

ODG vs PDF — Format Comparison

Compression Type — When to Pick Which

The "Compression Type" dropdown maps to Ghostscript's standard PDF settings, which trade file size for image fidelity. The image quality slider is independent — it controls JPEG quality of any rasterized image content embedded inside the drawing.

For pure-vector ODG content (shapes, text, lines drawn in Draw), all five settings produce visually identical output — vectors are not downsampled. The setting only matters when your .odg has embedded bitmaps (a logo PNG, a screenshot, a photo).

Frequently Asked Questions

Are vector shapes preserved as vectors in the output PDF?

In this tool the ODG is rendered to a high-quality image and embedded as one page per file, so shapes are rasterized rather than carried through as PDF vector objects. To keep vectors crisp at any zoom, pick Printer or Prepress under Compression Type and raise Image Quality to 95–100. If you specifically need vector-preserving export and you have LibreOffice locally, opening the file in Draw and using File → Export As → Export as PDF preserves shape geometry.

My multi-page ODG only exported one page in LibreOffice. Will this tool include all pages?

That LibreOffice behaviour is a known footgun: the "Export Directly as PDF" toolbar button exports only the currently selected page if a single page is highlighted, with a fix being to use File → Export As → Export as PDF… and select "All" in the Range section, or to deselect everything before exporting. This online tool treats each uploaded .odg file as one page, so for multi-page sources, save each page as its own .odg (or fix the export from Draw) before uploading.

Can I create one PDF per drawing instead of merging them?

Yes. Set "Combine?" to Individual PDFs and you'll receive a zip with one PDF per source .odg. Use this when you want separate deliverables but still want browser-only conversion without installing Draw on every machine.

What's the difference between Cover and Contained image placement?

Contained (default) scales the drawing to fit inside the page margins without cropping — this is what you want for technical drawings, schematics, and floor plans where every line matters. Cover scales the drawing to fill the entire page, cropping whatever doesn't fit the page aspect ratio — useful for full-bleed presentation graphics or poster-style layouts where you want zero white space.

Why does my merged PDF look bigger than the LibreOffice export?

Two common reasons. First, this tool rasterizes each ODG page; LibreOffice's native PDF export keeps vector shapes as vector objects, which compress better than images. Second, the Screen compression default downsamples raster content; if your drawings have embedded photos, switching to Ebook or Default and raising the Quality slider both shrink and sharpen output. For pure line drawings, the file size difference is mostly down to compression type.

What paper sizes are available?

A4 (default, 210×297 mm), A3 (297×420 mm), LETTER (8.5×11 in), LEGAL (8.5×14 in), TABLOID (11×17 in), LEDGER, EXECUTIVE, ARCH A (9×12 in), ARCH B (12×18 in), ISO B4, ISO B5, plus Original which uses each ODG's own page size (read from style:page-layout-properties in the file). For posters and large schematics, ARCH B or A3 is usually the right pick.

Will hyperlinks, layers, and form fields in my ODG carry over?

No — because each page is rasterized, interactive layers and clickable hyperlinks become flat pixels in the output. If you need clickable links in the PDF, do the export inside LibreOffice Draw instead and tick "Create PDF form" / "Export bookmarks" in the PDF options dialog.

Can I merge ODG with other formats?

Not in this tool — the input list is restricted to .odg. To combine ODG output with images or other PDFs, run this merge first, then use Merge PDF to add the result to other PDFs, or Merge Image to PDF for mixing photos and drawings into a single document.

What if I just want a single ODG converted, not merged?

Use Convert ODG to PDF for one-file conversions, or ODG to PNG, ODG to JPG, and ODG to SVG if you need a raster image or SVG instead of PDF.
