ToolBox Image — Como reduzir o tamanho do arquivo de imagem sem perder qualidade
Cinco técnicas comprovadas para reduzir o tamanho de arquivos de imagem mantendo cada pixel nítido. Da seleção de formato ao redimensionamento inteligente.
The most common question we hear is, "How do I make this image smaller without making it look worse?" Here are five techniques that work every time.
1. Switch to a modern format
This is the single biggest lever. Converting a JPEG to WebP saves 25-35% with no visible difference. Converting to AVIF saves 50-60%.
2. Remove invisible metadata
Every photo from a modern smartphone carries embedded EXIF data that can add 50-200 KB per image. Stripping it removes zero visual quality but reduces file size noticeably.
3. Resize to the display size
The most common cause of oversized images is uploading a 4000-pixel-wide photo when the page displays it at 1200 pixels. Resize first.
4. Use lossless compression for graphics
For screenshots, logos, and images with text, lossy compression introduces visible artefacts. Use lossless WebP or PNG instead.
5. Target a specific file size
Instead of guessing at quality sliders, tell the compressor the exact file size you need. Our target-size mode works backwards from the limit.
