How much can images be compressed?

Typically 50-80% file size reduction while maintaining good visual quality.

What formats are supported?

JPEG, PNG, WebP, and GIF formats are all supported.

How do I compress an image without losing quality?

Use our quality slider set between 75-85% for optimal results. This reduces file size by 50-70% while maintaining visual quality that's indistinguishable to the human eye. For lossless compression, use PNG format at 100% quality.

What image formats can I compress?

Our compressor supports JPEG/JPG, PNG, and WebP formats. JPEG is best for photos (60-80% size reduction), PNG for graphics with transparency (convert to WebP for a much smaller file that keeps the transparency), and WebP offers the best compression for modern browsers (70-85% reduction).

Is it safe to compress images online?

Our image compressor is 100% safe and private. Unlike other tools, your images never leave your device - all processing happens locally in your browser using JavaScript. No files are uploaded to any server.

How much can I reduce image file size?

Typical compression results: JPEG photos can be reduced by 60-80%, PNG graphics are already lossless, so convert them to WebP for big savings, and WebP images by 70-85%. The exact reduction depends on the original image and quality setting you choose.

Can I compress multiple images at once?

Yes! Our batch compression feature lets you compress unlimited images simultaneously. Simply drag and drop multiple files or select them from your file browser. All images are processed in parallel.

What's the best quality setting for web images?

For web use, 70-80% quality provides the best balance of file size and visual quality. This typically reduces file size by 60-70% while maintaining excellent visual fidelity. Google recommends images under 100KB for optimal page speed.

Does compression affect image resolution?

No, compression only reduces file size, not image dimensions. Your images will maintain their original width and height. If you need to resize images, use a separate image resizer tool.

Can I compress images on my phone?

Yes! Our image compressor works on all devices including iPhones, Android phones, and tablets. The responsive interface is optimized for touch screens and mobile browsers.

What's the difference between lossy and lossless compression?

Lossy compression (JPEG) removes some image data for smaller files - great for photos where minor quality loss is invisible. Lossless compression (PNG at 100%) preserves all data - essential for graphics, logos, and screenshots where every pixel matters.

How do I compress images for email?

Set quality to 70-75% for email attachments. This typically reduces photos to under 500KB while maintaining good quality. Most email services have a 25MB attachment limit, so compress large photos before sending.

Is this better than TinyPNG or Squoosh?

Unlike TinyPNG which uploads files to their servers, our tool processes everything locally for complete privacy. Unlike Squoosh, we offer batch processing. Plus, we're completely free with no daily limits or signup required.

Can I compress images for Instagram or social media?

Yes! For Instagram, compress at 80-85% quality. Instagram recommends images between 1080-2048px wide. Our tool preserves dimensions while reducing file size, ensuring fast uploads and optimal display quality.

Why are my compressed images larger than the original?

This can happen with already-compressed images or very small files. Try using a lower quality setting, or the original may already be optimally compressed. PNG files converted from JPEG may also be larger.

Does the compressor work offline?

Yes! Once the page loads, you can compress images without an internet connection. All processing uses local JavaScript and WebAssembly, making it perfect for areas with limited connectivity.

How do I compress an image to an exact size like 20KB or 50KB?

This compressor works by quality percentage. When a form gives a KB limit, use Compress Image to KB (edesy.in/tools/compress-image-to-size): enter the limit and it finds the best quality that fits, with optional pixels or cm and DPI. Presets exist for 20KB, 50KB and 100KB.
