What is the difference between JPEG and PNG?

JPEG and PNG are both raster-based image formats, meaning they consist of pixels rather than resizable shapes or vectors. The main difference between these two formats is how they handle compression—the process that reduces file size.

JPEGs reduce file size by removing some image data. This is OK for photographs or web images where fine detail isn’t essential, but it can make text, graphics, or sharp edges blurred or pixelated.

PNGs use lossless compression, so no image data is lost when the file is saved. File sizes are larger than JPEGs, but PNG is a better format for logos, icons, or graphics with text.

PNGs also support transparent backgrounds, making them useful when you need to place an image on top of another background.

Use QuillBot’s free online JPEG converter if you need to convert a JPEG to a PNG.

When you need to brainstorm ideas for an AI illustration, QuillBot’s AI Illustration Generator is completely free to use.

You can also put your visual detection skills to the test with our Human or AI game.
Is aspect ratio the same as pixels?: No, there is a difference between pixels and aspect ratio. A website or app might ask you for a certain pixel size (e.g., 400 x 400), which would be a 1:1 aspect ratio. But 800 x 800 pixels is also 1:1.

Whenever you upload something to social media or send it for printing or publishing on the web, it is important to pay attention to aspect ratio requirements and pixel size.

Using the right aspect ratio will make sure your image fits the shape of the available space, and using the right pixel size will make sure your image has enough detail but isn’t so large that it slows down the loading time for the page (very bad for search engine rankings).

What’s the difference between lossy and lossless compression?: File size and image quality are the main differences between lossy and lossless compression.

Lossy compression makes an image file smaller by deleting data that isn’t essential. It reduces image quality in a way that isn’t noticeable to everyday users.

Lossless compression reduces an image’s file size by reorganizing the data instead of permanently deleting any of it, so the quality stays the same.

An image file format that supports lossless compression is AVIF, which isn’t universally compatible. When you need to convert AVIF to a more compatible format, QuillBot’s AVIF converter is completely free to use.
Can I convert AVIF to JPG without losing quality?: You can convert AVIF to JPG without losing quality that’s noticeable to an everyday user. JPG uses lossy compression, so very small quality losses may occur. If you want to preserve all details, converting to a lossless format like PNG or WEBP is a better option.

QuillBot’s free AVIF converter supports several image formats, so you can choose the one that best fits your needs.
Is JPG good for web pages?: Although you can use JPG/JPEG images on a website, it can affect load times, and this in turn can harm the ranking of your site. It is much better to convert your images to the faster .webp format.

The easiest way to do this is with a converter like QuillBot’s free online JPG converter.
What’s the meaning of leverage in business?: “Leverage” in business is the process of borrowing money, investing those funds, and planning for the future returns on investment to be greater than what it costs to repay the debt.

What size is a hero image?: A full-screen hero image is typically sized at 1280 × 720 pixels with a 16:9 aspect ratio, ensuring clarity on most screens. However, depending on your site’s design and target devices, you might opt for larger dimensions, such as 1600 × 900 pixels or 1920 × 1080 pixels, to maintain image quality on high-resolution displays.

Always test your image across various devices to ensure it loads quickly and appears sharp. You can use QuillBot’s AI Image Generator to create high-quality visuals that fit your design, then adjust them as needed.
Why do they call it a hero image?: The term “hero” comes from theater, where a hero prop is an object crafted in full detail because it will be seen up close and is central to the scene.

A common size for a website logo is about 250–400 pixels wide by 70–100 pixels high. You can really design your logo in any size, but make sure you do so in vector format (e.g., SVG) so it looks sharp if you shrink or enlarge it.

QuillBot’s AI logo generator can help you experiment with different logo sizes.
What is a background?: A background for a presentation, social media post, web page, or other digital image is the foundational layer of a design that supports the main content in the foreground. It provides visual context, depth, and atmosphere while ensuring that text, images, or other focal elements remain clear and engaging.

QuillBot’s free AI background generator makes bringing your creative background ideas to life quick and easy.

How long does it take to generate an image with an AI generator?: In most cases, it takes from a few seconds to under a minute for an AI image generator to create a high-quality image from your image prompt. Some advanced tools may take slightly longer depending on:

The complexity of your prompt (e.g., intricate scenes or layered styles)

The resolution or aspect ratio you’ve selected

Server load or tool performance at the time you’re using it

If you’re refining your image through multiple iterations, allow a little extra time for edits and prompt adjustments.

Most advanced tools, like QuillBot’s AI image Generator, offer preset styles, aspect ratios, and prompt suggestions to help streamline the process and ensure your image is optimized right from the start.
How do AI image generators work?: AI image generators transform text-based prompts (i.e., what you describe) into visual images using machine learning models that have been trained on millions of images and descriptions.

When you input an image prompt (like “a trapeze artist walking across a tightrope”), the AI model interprets the words, identifies patterns based on its training data, and then generates a completely new image that matches your description.

This process involves the following steps:

Text understanding: The AI parses your prompt to understand key elements like subject, style, lighting, setting, and mood.

Pattern matching: It uses deep learning to reference visual patterns and styles it has seen during training.

Image rendering: The AI tool assembles those concepts into a new image.

Advanced tools like QuillBot’s AI image generator make this even easier by offering preset styles and aspect ratios that help guide the AI toward more accurate and creative results.

Now that you know how AI creates images, see if you can tell which ones are AI-made. Take our Human or AI quiz to test your detection skills.
How to use an AI image generator to create visuals?: Creating visuals with an AI image generator is quick and easy. All you need is a clear idea and a well-written prompt.

Here’s a simple step-by-step process:

Describe your image: Write a detailed image prompt including the subject, style, mood, and composition (e.g., “Cyberpunk city at night, wide-angle view, neon lights”).

Choose your settings: Select a style, aspect ratio, or use the automatic presets to guide the AI (tools like QuillBot’s AI Image Generator offer built-in options to simplify this step).

Generate and refine: Once you’re happy with your prompt and settings, click to generate. Most images are ready in seconds. If needed, tweak your prompt or use negative prompts to refine the result.
