A chart or diagram exported as SVG from a data visualisation tool or design software often needs to become a plain image before it can be dropped cleanly into a presentation slide, since not every presentation tool handles embedded SVG consistently or at all. Converting to PNG at the right size for your slide avoids display issues and keeps the chart looking sharp.
Steps
- Determine the size the chart will actually be displayed at within your slide.
- Upload the SVG to SVG to PNG and export at a size somewhat larger than the actual display size, to allow for sharpness on higher-resolution displays and projectors.
- Insert the PNG into your presentation slide at the intended display size.
Why exporting larger than the display size matters for presentations
Presentations are often viewed on a large screen or projector, sometimes at a size considerably bigger than a laptop screen, which means a chart needs more actual pixel detail to stay sharp than it might for typical on-screen use. Exporting at roughly one and a half to two times the intended display size, since SVG allows this with no quality cost, gives a comfortable margin of sharpness for large-screen presentation.
Why SVG support varies across presentation software
Some presentation tools handle embedded SVG well; others display it inconsistently, fail to render certain SVG features correctly, or do not support it at all, depending on the specific software and version. Converting to PNG sidesteps this uncertainty entirely, since PNG support is universal and consistent across every presentation tool.
Keeping chart text legible at presentation size
A chart with small axis labels or a dense legend, designed to be viewed up close on a screen, can become difficult to read once displayed large on a presentation screen and viewed from a distance by an audience. Before finalising, check whether the chart's text and detail remain comfortably legible at the size and viewing distance your actual presentation will involve, and consider simplifying or enlarging specific elements in the source chart if not.
Keeping the chart's background transparent or matched to your slide
If your SVG chart has a transparent background, this can be preserved in the PNG export, letting the chart sit naturally on a slide with its own background colour or design. If your slide background is not plain white, check that a transparent chart export actually looks correct against it, since some slide themes or colours can interact oddly with certain transparent elements.
Updating a chart after the data changes
If the underlying data changes, re-export a fresh chart from your source tool and convert that updated SVG to PNG again, rather than trying to manually edit numbers directly on an already-converted PNG image, which loses the underlying chart structure and is generally much harder to edit accurately than regenerating from the source data.
Preparing several charts consistently for the same presentation
If a presentation includes several charts, export them all at a consistent scale and style, so they appear uniform in quality and sizing throughout the deck rather than some looking sharper or differently proportioned than others. Establishing your export settings once and applying them consistently across every chart in the same presentation keeps the whole deck looking cohesive.
Choosing the right export resolution for a slide
A presentation slide, especially if it'll be projected on a large screen, benefits from a higher-resolution PNG export than the same chart might need for a web page. Export at a size comfortably larger than the slide's actual display area, so the diagram stays sharp rather than looking soft when scaled up on a big screen, particularly if audience members further back in the room need to read finer details or axis labels clearly.
Checking colours and text remain legible once converted
Some SVG charts use fine lines or subtle colour distinctions that read clearly on a screen at close range but can wash out when projected under bright room lighting. Preview the converted PNG at roughly the size and lighting conditions it'll actually be presented under, if you're able to, and adjust line weights or colours in the source SVG beforehand if anything looks likely to be hard to distinguish from the back of a room.
Keeping the original SVG for future edits
Keep the original SVG file saved alongside the exported PNG, since the SVG remains editable if the chart's data or design needs updating later, while a PNG exported from it does not. Re-exporting from an updated SVG is far simpler than trying to edit a flat PNG image directly.
Frequently asked questions
Why not just embed the SVG directly if my presentation tool supports it?
If your specific tool handles SVG reliably, that is a reasonable option; converting to PNG is the safer, more universally compatible choice when support is uncertain or the presentation might be opened in different software later.
What size should I export a chart at for a large presentation screen?
Export at roughly one and a half to two times the actual display size within your slide, to maintain sharpness on a large screen or projector.
Will the chart's colours look the same once converted?
Yes, the conversion preserves the chart's colours as designed in the SVG.
Can I edit the chart's data after converting to PNG?
Not directly; re-export a fresh chart from the source data and convert again if the underlying data changes.
Does a transparent background survive the conversion?
Yes, PNG supports transparency, so a transparent SVG background is preserved in the converted file.
Should every chart in a presentation use the same export settings?
Yes, for visual consistency across the whole deck, keep your export scale and style consistent across every chart included.
Is the tool free and private?
Yes. No sign-up, no watermark, and files are removed from the server automatically about an hour after processing.
