Convert old BMP artwork for a presentation deck

Old BMP artwork may look fine on your computer but be awkward to add to a presentation. The file can be large, or the presentation app may not handle it as expected. Converting it to PNG or JPG can make it easier to place in a slide deck.

Use the Image Converter to convert BMP images in your browser. This guide explains which format to choose, how to convert one or several files, and what to check if the result looks different.

Convert BMP artwork for your slides

1. Open the Image Converter and select the BMP artwork from your device. You can add up to 50 images at once.
2. Choose PNG for drawings, diagrams, logos, text, or artwork that needs a transparent background. Choose JPG for photographs when a smaller file is more important than preserving every pixel exactly.
3. Choose the output format and start the conversion. The converter supports JPG, PNG, WEBP, GIF, BMP, ICO, and TIFF.
4. Save the converted file to your device. Give it a clear name, such as opening-slide-artwork.png, so it is easy to find when you insert it into the presentation.
5. Open the converted image and check it at the size you plan to use. Look closely at small text, fine lines, edges, and any transparent areas before adding it to the deck.

The converter handles the file format, not the artwork itself. It does not improve a small or blurry source image, remove a background, or restore detail that is missing from the original.

Choose the right format

Use PNG for illustrations and crisp edges

PNG is usually a good choice for drawings, icons, charts, screenshots, logos, and artwork with lettering. It preserves sharp edges well and uses lossless compression, which means the conversion does not intentionally discard image detail. PNG also supports transparency, though converting a BMP will preserve transparency only if the source file already contains it and the image data supports it.

PNG files can still be large, especially for high-resolution artwork or images with many colors. If the deck becomes too large to email or share, check whether the image needs to appear at its original dimensions. Do not shrink it so much that details become hard to see.

Use JPG for photographs

JPG is often practical for scanned paintings, photos, and other continuous-tone images. It can make files much smaller, which helps keep a presentation manageable. JPG uses lossy compression, so it throws away some image information. Fine lines, lettering, and sharp color boundaries can look softer or show faint blocks after conversion. Avoid repeated JPG conversions, because each save can introduce additional compression.

JPG does not support transparency. If your artwork needs to sit over a colored slide without a rectangular background, use PNG instead. If the BMP has a solid background, converting to JPG will keep that background rather than make it transparent.

Use WEBP only when your presentation supports it

WEBP can produce compact files, but not every presentation program or older computer handles it reliably. If you will present on another computer, send the deck to someone else, or export slides through different software, PNG or JPG is generally a safer choice. Test the deck on the system you will use before relying on a less familiar format.

If the converted image looks wrong

• The artwork looks blurry. Check the image dimensions and compare the converted copy with the original at the same zoom. Conversion does not add pixels. If the original is too small for the slide, find a larger source or use the artwork at a smaller size.
• Text or thin lines look rough. Try PNG instead of JPG. JPG compression is more noticeable around sharp edges and small text. If the BMP is already low quality, changing formats cannot recreate the original detail.
• A white or colored box appears behind the artwork. The source probably has a solid background, or its transparency was not stored in a format the converter could preserve. PNG can retain existing transparency, but conversion does not automatically cut out a background. Use an image editor to remove the background if needed.
• The colors look different in the slide deck. Compare the image in a separate viewer and inside the presentation. Color profiles, display settings, and the slide app can affect how colors appear. Keep the original BMP so you can compare or try another output format.
• The file will not insert into the presentation. Convert it to PNG or JPG and try again. Also check that the converted file finished saving and that you selected the new file rather than the original BMP.

Keep the original artwork

Save the BMP until you have checked the presentation on the computer or service where it will be shown. Keep the converted copy in the same project folder, and use a name that identifies the format. This makes it easier to replace the slide image if the presentation software handles one format better than another.

Image Converter works in your browser, and the files you open stay on your device.
