Free Image Compressor – Shrink JPG & PNG Files Instantly
PureDoc's Image Compressor helps you reduce the file size of your photos and graphics without leaving your browser. Adjust the quality slider to find the perfect balance between small size and good quality. All processing is done locally using HTML5 Canvas – your images are never uploaded, keeping them private and secure.
Why Compress Images?
Large images slow down websites, take forever to send via email or WhatsApp, and eat up your storage space. Whether you are a blogger, freelancer, or just sharing photos with friends, compressing images makes them load faster and easier to share. Our tool lets you reduce a 5MB photo to under 500KB while still looking great.
⭐ Key Features
- Real‑time preview – See original vs compressed side‑by‑side.
- Quality slider – Fine control from 10% to 100%.
- Shows file size – See how many KB you saved.
- 100% local – No upload, total privacy.
- Supports JPG and PNG – PNG compression uses lossy mode (saves a lot).
💡 Pro Tips for Best Compression
For most photos, 75–85% quality is the sweet spot – you won’t notice a difference but the file size drops dramatically. For PNG images (like logos or screenshots), our tool converts them to JPG internally for compression; if you need transparency, better to keep PNG format separately.
