BeFunky currently supports saving in JPEG and PNG file formats.
When should you save as JPEG?
JPEGs are most useful for digital photography and online image sharing, as it is a widely supported web format and allows for smaller file sizes. JPEG has the ability to hold camera-specific information within an image's metadata, making it useful for real world photography.
JPEGs are 'lossy' compressed files, meaning each time you reopen and re-save a JPEG you will lose trace amounts of quality. It also cannot support image transparency.
Avoid JPEG When: You are using text-heavy images and graphics with sharp lines, or when you plan to save numerous times throughout the editing process. If you have transparent elements you want to retain within your image, saving as a JPEG will not allow this.
Takeaway: Keep JPEG exports minimal to maintain best possible image quality. Finding a balance of low file size and high image quality is the sweet spot of saving as a JPEG.
When should you save as PNG?
Unlike JPEG files, PNG has lossless compression, so you'll have zero loss in quality even if a file has been repeatedly re-opened and saved. It also supports image transparency which makes it great for brand images, logos, text heavy images and screenshots.
Avoid PNG When: If you're saving photorealistic images, JPEG should be used over PNG. PNG should also be avoided when you're working with images that contain important metadata relating to the camera used to capture it.
Takeaway: PNG is best for digital graphics and non-photorealistic images. You won't lose data when re-opening and re-saving, and PNG supports the use of transparency.
Other Best Practices:
- Consider saving a copy of your project as BFD file, which will retain all your project layers for future editing.
- Understanding image resolution will help with choosing a file type. If you're planning on printing a file instead of saving only for the web, you may want to factor that into your decision.
- Be aware of file sizes when saving. Images that will be displayed on the web display best at file sizes of 500kb to 1mb. If you're displaying many images with heavy file sizes on a single webpage, you may see performance issues.
