JPG, PNG, or WebP - up to 20 at once. Images larger than 2400px are resized for the web. Nothing is uploaded; compression happens on your device.Why WebP, and how much it saves
WebP is the modern image format supported by every current browser. At comparable visual quality it typically produces files 25-35% smaller than JPEG and far smaller than PNG photographs - and since images are usually the heaviest part of a web page, converting them is the single fastest page-speed win available. This tool also resizes anything wider than 2400 pixels, because images straight off a phone camera are several times larger than any screen will ever display.
Your photos never leave your device
Unlike upload-based compressors, everything here happens locally in your browser using the canvas API: the files are read, resized, re-encoded, and handed back to you without touching any server. That makes the tool safe for client work, unreleased products, and anything confidential - and it means no file-count limits, no watermarks, and no queue.
Frequently Asked Questions
80% is the sweet spot for most web photos - significant savings with no visible difference at normal viewing sizes. Drop toward 60-70% for backgrounds and thumbnails; raise toward 90% for photography portfolios where detail is the product.
WebP, in almost all cases: every modern browser supports it and files come out meaningfully smaller. Choose JPEG only when the image must open in older desktop software or be emailed to recipients with legacy systems.
No. Compression runs entirely in your browser - files are processed on your device and never transmitted. You can verify this by loading the page, disconnecting from the internet, and compressing; it still works.
As a rule: hero images at most 1920-2400px wide, content images 800-1200px, thumbnails 400px - and almost everything under 200 KB, with most content images under 100 KB. If a page carries multiple megabytes of imagery, compression is your fastest speed fix.
Heavy Images Are Usually Just the First Problem
If your site is slow, images are the quick win - render-blocking scripts, hosting, and code usually hide bigger ones. We build sites that load in under 2 seconds.
