Supports JPG, PNG, WebP, GIF, SVG • Up to 50 images • No size limit
For web images, 80% JPEG quality is usually indistinguishable from 100% but 3-5x smaller.
Stripping EXIF data can reduce file size by 50-100KB and removes location/camera info for privacy.
WebP format produces files 25-35% smaller than JPEG at the same visual quality.
Most government portals and job applications require photos under 100-200KB. Use our Target Size mode to hit the exact requirement.
Image compression reduces file size by removing redundant data from your image files. There are two main types of compression: lossy and lossless. Understanding the difference helps you choose the right settings for your needs.
Lossy compression (used by JPEG and WebP) permanently removes some image data to achieve smaller file sizes. At quality levels above 70-80%, the visual difference is nearly impossible to detect with the naked eye, even though the file might be 5-10x smaller. This is the recommended approach for photographs and most web images.
Lossless compression (used by PNG) preserves every pixel exactly as the original. File sizes are larger, but there is zero quality loss. This is ideal for screenshots, logos, diagrams, and any image where pixel-perfect accuracy matters.
JPEG (JPG) is the best choice for photographs and complex images with many colors and gradients. It offers the best compression ratios for photographic content but does not support transparency.
PNG is ideal for screenshots, logos, icons, and graphics with text or sharp edges. It supports transparency (alpha channel) and preserves crisp lines that JPEG would blur. File sizes are larger than JPEG for photographs.
WebP is a modern format that combines the best of both worlds. It supports both lossy and lossless compression, transparency, and produces files 25-35% smaller than JPEG at equivalent quality. It is supported by all modern browsers and is the recommended format for web use.
| Use Case | Max Size | Notes |
|---|---|---|
| Passport / Visa applications | 100 KB | Government portals often require exactly 100KB or less |
| Job application forms | 200 KB | Many HR portals cap photo uploads at 200KB |
| Email attachments | 500 KB | Keep images under 500KB for fast email delivery |
| Website images | 100-300 KB | Larger images slow down page load times |
| Social media uploads | 1-5 MB | Most platforms auto-compress, but smaller uploads process faster |
Most online image compressors upload your files to their servers for processing. This raises privacy concerns, especially for sensitive documents like passport photos, medical images, or personal photographs. Our compressor processes everything directly in your browser using the Canvas API — your images never leave your device, are never stored anywhere, and are never seen by anyone else.
