Upload files
Compress batches of JPEG, PNG, WebP and static AVIF images without sending local file bytes to the server.
Open the compressorCompress images from files or URLs.
Make images smaller, convert formats and fix heavy webpage assets.
One optimization engine, wherever your image starts.
Use files already on your device, fetch one public image URL, or scan a webpage for image candidates. Compression, conversion, resizing and downloads still happen in your browser after an image is selected.

Use an image URL
Import one public image, then apply the same local quality, format, resize, naming and target-size controls.
Open the URL tool.webp&w=3840&q=75)
Scan a webpage
Find discoverable image candidates on one public page, select the useful ones and create a local replacement bundle.
Open the scannerYour local images stay local.
Upload mode decodes, resizes, compresses, converts and packages images on your device. Local filenames, pixels and metadata are not sent to our server for processing.
URL modes make limited network requests because remote resources must be fetched. Private networks are blocked, redirects and content types are checked, and fetched images return to the browser for optimization.

Practical notes on lighter images and the websites that serve them.
How to fix “Improve image delivery” in PageSpeed Insights
Diagnose PageSpeed image delivery warnings by separating oversized pixels, inefficient encoding, and slow loading. Includes a deployment checklist.
How to find large images on a website
A useful audit separates transfer weight, intrinsic pixel dimensions and rendered size. One number cannot tell you whether an image is actually a problem.
Responsive images: get srcset and sizes right for your layout
Build responsive image variants using real slot widths, pixel density, and browser-selected sources. Includes a complete HTML card example.
WebP vs AVIF vs JPEG: choose by the image
There is no permanently smallest format for every image. Start with the content, browser requirements and transparency needs, then compare outputs from the same source.
Fix GTmetrix “Efficiently encode images” with a controlled quality check
Reduce unnecessary image bytes without confusing compression with resizing. Use a practical export comparison and verify the replacement on your live page.
Get an image under 200 KB without making it unusable
Meet a 200 KB upload limit by balancing dimensions, format, and visual clarity. Learn when quality alone cannot reach the target and how to verify the output.
