Image compression reduces the file size of your photos and graphics without significantly affecting their visual quality. Smaller images load faster on websites, use less storage space, and are easier to share via email or WhatsApp. For websites, compressed images directly improve Google rankings because page speed is a core ranking factor.
JPG (JPEG) is best for photographs and images with many colors. It uses lossy compression, making files very small — ideal for social media, WhatsApp, and website hero images.
PNG is lossless and supports transparency, making it perfect for logos, icons, and screenshots where sharp edges matter.
WebP is a modern format developed by Google. It is up to 30% smaller than JPG at the same quality and supports transparency like PNG. Use WebP for websites to improve Core Web Vitals and loading speed.
Lossy compression permanently removes some image data to achieve smaller file sizes. At 80% quality, most people cannot tell the difference between the original and compressed image. JPG and WebP use lossy compression.
Lossless compression reduces file size without removing any data — the image is pixel-perfect after decompression. PNG uses lossless compression. Use lossless when you need to preserve every detail, such as medical images, design files, or text-heavy graphics.
For WhatsApp: Compress to 70–80% quality. WhatsApp further compresses images before sending, so starting with a smaller file preserves more quality in the final result.
For email attachments: Keep image files under 1MB. Use 70% quality for photos. This ensures emails deliver quickly and do not bounce due to attachment size limits.
For government forms (SSC, UPSC, IBPS): Most Indian government portals require photos under 50KB and signatures under 20KB. Use our tool and set quality to 40–50% to hit these limits. Always check the exact requirements on the official notification before uploading.
For most photographs, compressing to 75–85% quality reduces file size by 60–80% with virtually no visible difference. A 5MB photo typically compresses to 500KB–1MB at 80% quality. For graphics with text or sharp lines, stay above 85% to avoid compression artifacts. Use our quality slider to find the right balance for your specific image.
Everything you need to know about compressing images online.
WebAuzar supports all major image formats including JPG, JPEG, PNG and WebP. You can compress files up to 50MB each.
Our tool uses your browser's built-in canvas API to re-encode images at your chosen quality level. Everything happens locally on your device — no files are ever sent to any server.
It depends on the quality level you choose. At 80% quality (Balanced preset), most images look identical to the original but are significantly smaller. You can always adjust the slider before compressing.

Absolutely. Your images never leave your device. All processing happens locally in your browser — we have zero access to your files.
JPEG is best for photos with many colors. PNG is lossless and ideal for graphics with transparency. WebP offers the best of both — smaller file sizes than JPEG at the same quality, with transparency support like PNG.
You can convert your image to a different format while compressing. For example, convert a PNG to WebP to get a much smaller file. Choosing 'Original' keeps the same format as your input.
