What This Tool Optimizes
The compressor focuses on practical web output: smaller files, acceptable visual quality, and repeatable settings for bulk work. It is designed for users who need quick results without opening a desktop editor. The best results usually come from combining quality reduction with sensible max-resolution limits.
Quality, Max Size, and Resolution
Start with quality around 75-85% for photos and 85-90% for screenshots or images with text. If the file is still too large, reduce max resolution before lowering quality aggressively. A 4000px camera photo often shrinks more cleanly when capped at 1600-1920px than when quality is pushed too low.
Compress Image to KB or MB Targets
The max file size slider lets you aim for a specific upload target, such as 100KB or 500KB. Exact output can vary because image content matters: a flat graphic, a screenshot, and a detailed photo each compress differently. If a target is not reached, lower quality slightly or reduce the max resolution.
JPG, PNG, and WebP Behavior
JPG photos usually compress the most. PNG screenshots and transparent graphics may shrink less because they preserve sharp edges and alpha data. WebP often starts smaller than JPG or PNG, so the percentage reduction may be lower even when the final file is already efficient.
Privacy and Workflow
Compression is performed in the browser session. That makes this tool suitable for fast internal workflows where you need immediate output and bulk download support.
