Image Compressor – Reduce File Size Without Losing Quality

The compressor supports JPG/JPEG, PNG (including transparent PNGs), WebP, AVIF, and GIF. You can also convert between formats — for example, compress a PNG to WebP for even smaller file sizes while maintaining transparency support.

Yes. Helperzy supports batch compression — upload as many images as you need, configure your quality settings once, and compress them all simultaneously. When done, download individual files or grab everything in a single ZIP archive.

Each image can be up to 50 MB. Since all processing happens in your browser, there are no server-side upload limits. You can compress as many images as your device memory allows.

By default, no — compression only reduces file size. However, you can optionally resize images using the Max Dimension slider (320px to 4096px) if you want to reduce both file size and pixel dimensions simultaneously.

Upload your image, select the 'Maximum Compression' preset or set quality to 60-70%, and optionally reduce the max dimension to 1200px or lower. Click Compress and check the result. Most photos will compress well below 100KB with these settings while remaining visually clear.

Absolutely. All compression runs 100% in your browser using JavaScript and Web Workers. Your images are never uploaded to any server, never stored anywhere, and never seen by anyone. When you close the tab, all data is automatically cleared from memory.

WebP offers the best compression-to-quality ratio for web use — typically 25-35% smaller than equivalent JPEG at the same visual quality. Use the format conversion feature to convert your images to WebP for optimal page load performance and Core Web Vitals scores.

Helperzy pe apni image upload karo, quality slider ko 80% pe rakho (ya 'Balanced' preset select karo), aur Compress button dabao. Aapki image ka size 60-80% kam ho jayega aur quality bilkul same dikhegi. Koi signup ya download ki zaroorat nahi.

Yes. After compression, click the 'Compare' button on any image to open an interactive side-by-side slider. Drag the slider left and right to see exactly how the compressed version compares to the original — pixel by pixel.
