    Frequently Asked Questions

    Here are some common questions and answers about mp4 file conversions ask by our users on RunConvert.com.

    Q: How do I convert an image to a web-friendly format?

    A: For web use, we recommend converting images to JPEG or WebP, as these formats balance good quality with small file sizes. You can use RunConvert to easily convert your images into these formats and optimize them for faster website loading times.

    Q: How can I be sure my converted image is safe?

    A: Your privacy matters to us! We process images securely, and once the conversion is done, your image is automatically deleted from our servers.

    Q: Do I need to worry about copyright issues when converting images?

    A: When using RunConvert, make sure you have the rights to the images you’re converting, especially for commercial use. We recommend using images that you own or have permission to use to avoid any copyright complications.

    Q: Do you support RAW image formats from cameras?

    A: We currently don’t support RAW formats like CR2 or NEF directly. However, you can convert those to JPEG or TIFF through image editing software before uploading them to RunConvert.

    Q: Is there a way to change the DPI of an image during conversion?

    A: Unfortunately, DPI changes aren’t part of the typical conversion process. However, you can resize and adjust image resolution before converting it to different formats. For DPI adjustments, consider using image editing software.

    Q: How can I get help if I have trouble converting my image?

    A: If you run into any issues, our support team is always here to help. Just reach out through our contact form or live chat, and we’ll guide you through solving any problems.

    Q: Why do my converted images look pixelated?

    A: Pixelation happens when an image is resized or converted to a lower-resolution format. To avoid this, choose a high-resolution source image and a format that supports better quality.

    Q: How do I convert a photo to a vector graphic?

    A: To convert a photo to a vector graphic, you need to use a process called vectorization, which is typically done using specialized software. While RunConvert can help you convert raster photos to vector formats like SVG or EPS, the quality may vary depending on the complexity of the image.

    Q: What’s the best format for printing images?

    A: For print-quality images, we recommend TIFF or PNG as they retain the best resolution and color depth. Avoid JPEG for print if possible, as it’s a lossy format and may degrade quality when printed at large sizes.

    Q: Can I convert images to a PDF with multiple pages?

    A: Yes, you can convert multiple images into a multi-page PDF. Upload your images, and RunConvert will combine them into a single PDF file with each image on a separate page.
