Free browser-based tool
Compress Image Online
Reduce JPG, PNG, and WebP file sizes with full quality controls. Runs entirely in your browser — nothing is uploaded to any server.
⚡ Built for website speed
Large images are one of the easiest ways to slow a page down. This tool is part of a practical workflow for smaller, cleaner, faster visual assets.
📈 Better for SEO too
Correctly sized, compressed images improve page experience scores, reduce bounce rate, and can contribute to better Core Web Vitals performance.
When to use this tool
Use the image compressor before uploading photos to a website, sending files by email, building product listings, publishing blog posts, or preparing social media graphics. Large original files — especially DSLR camera photos — are almost always much bigger than they need to be for web display.
Best settings for common use cases
Website photos: Resize first to the actual display width, then export as WebP at 80–85% quality. For most hero images, 1200–1600px wide is enough. A well-compressed WebP photo should be well under 200KB.
Blog post images: 1200×675px JPG or WebP at 80–84% quality. Check sharpness of any text in the image before publishing.
Product photos: 1200×1200px for most marketplaces. Use "fit inside" mode to avoid cropping. Export as JPG at 85% for a clean balance of quality and size.
Social graphics: Use a preset (Instagram Square, Facebook Post, etc.) and set fit mode to "crop exact" so the result fills the frame.
Quality and format guide
JPG: Best for photographs, product images, and any image without transparency. 80–88% quality is usually indistinguishable from 100% at web viewing sizes. Do not use JPG for logos or text-heavy graphics.
PNG: Use for images that need transparent backgrounds, screenshots, logos, and graphics with sharp edges. PNG is lossless — quality settings do not apply the same way. File sizes will be larger than JPG.
WebP: Best choice for most modern website images. Supports both lossy and lossless compression. Smaller files than JPG or PNG at equivalent visual quality. Supported by all modern browsers.
Before you download
Preview the result at actual display size. Check important details: faces, text, product edges, logos, and fine shadows. If the image looks blocky, blurry, or washed out, increase the quality slider or export at a larger pixel dimension rather than pushing compression too hard.
Frequently asked questions
Are my images uploaded to a server?
No. TinyImageLab tools run entirely in your browser using the HTML5 Canvas API. Your image is read from your local device, processed locally, and downloaded back to your device. Nothing is sent to any server.
Which format should I choose for a website photo?
WebP is the best choice for most modern website images — it delivers the smallest file sizes at good visual quality and is supported by all major browsers. If you need broad compatibility with older systems or email, JPG is a solid fallback. Use PNG only when you need transparency or a lossless graphic.
Will compression hurt my image quality?
At settings between 75–88%, most people cannot see a quality difference at normal web viewing sizes. Compression only becomes visibly damaging when pushed below 60–65%. Always preview text, faces, logos, and product edges before publishing.
What is the best way to reduce a large photo file?
Start by resizing the image to its actual display size — a photo that appears 800px wide on screen does not need to be 4000px wide. Resizing alone often reduces file size by 80–90%. Then apply compression on top for further reduction.
Can this tool help my website load faster?
Yes. Image file size is one of the biggest contributors to slow page load times. Smaller, correctly sized images reduce total page weight and can improve Core Web Vitals metrics like Largest Contentful Paint (LCP), which directly affects SEO.
