🖼️ Image Formats Glossary & Definitions
PNG (Portable Network Graphics): A lossless compressed raster format that records pixel data exactly as created. It supports full alpha transparency, making it the perfect choice for logos, typography, and clean graphic assets.
JPG / JPEG (Joint Photographic Experts Group): A lossy compressed raster format optimized for photograph color depth. It compresses file weights aggressively by discarding visually subtle variations, speeding up webpage loading.
WebP (Web Picture Format): Google's next-gen lossy and lossless image standard. It compresses image weights by 30% more than traditional JPEGs, directly boosting Google Core Web Vitals rankings.
SVG (Scalable Vector Graphics): An XML-based vector graphics standard. Rather than storing a grid of pixels, it stores geometric paths, enabling graphics to scale to infinite sizes with zero blurring.

Common Image Compressor scenarios
| Scenario | Why it matters | Recommended action |
|---|---|---|
| Website publishing | Smaller, compatible files improve page speed and user experience. | Convert or compress before uploading to a CMS. |
| Email and forms | Many portals reject files that are too large or in unsupported formats. | Use the converter, then check the output size before sending. |
| Mobile sharing | Phones often save modern formats that older apps cannot open. | Export to a common format with broad compatibility. |
Image Compressor format notes
Before converting, check whether your goal is smaller file size, stronger compatibility, editable output, or better visual quality. Lossy formats usually reduce file size, while lossless or document formats may preserve more detail but create larger files. When quality matters, keep a backup of the original source file and compare the result before deleting anything.
