Image Tools FAQ: Common Questions Answered

JPG (JPEG) uses lossy compression, making files smaller at the cost of some quality — ideal for photos. PNG uses lossless compression, preserving every pixel — ideal for logos, screenshots, and images requiring transparency (PNG supports alpha channels, JPG does not). Convert PNG to JPG or JPG to PNG with our free tools.

To preserve quality when resizing, only scale an image down (never up, as upscaling creates blur). Use bicubic or Lanczos resampling algorithms. Maintain the original aspect ratio by locking width-to-height proportions. For the best results with photography, resize from the highest-resolution original. Resize images free online here.

For web use, aim for images under 200 KB. Use JPG for photographs (quality 75–85% is usually imperceptible), PNG for graphics, and WebP for the best compression across both. Strip EXIF metadata to save additional space. Compress images for free here — our tool optimizes without noticeable quality loss.

A favicon is the small icon displayed in browser tabs, bookmarks, and search engine results next to your site's name. The traditional size is 16×16 or 32×32 pixels in .ico format. Modern browsers also support 180×180 PNG for Apple touch icons. Generate a favicon from any image for free.

A HEX color code is a six-character string (like #FF5733) representing a color in RGB. The first two characters are the red component, the next two are green, and the last two are blue — each in hexadecimal (00–FF = 0–255). HEX codes are universally used in HTML and CSS. Pick colors and get HEX/RGB/HSL values instantly.

SVG (Scalable Vector Graphics) is an XML-based image format that uses mathematical paths instead of pixels, so it scales perfectly to any size without quality loss. Use SVG for logos, icons, and illustrations. For photographs and complex imagery, use JPG or WebP instead. SVG files are also editable as text.

WebP is Google's modern image format offering significantly smaller file sizes than JPG and PNG at equivalent quality. It is supported by all modern browsers. Converting your images to WebP can meaningfully improve page load speeds and Core Web Vitals scores. Convert and compress images to WebP here.
