Compress Image FREE
Make JPEG, PNG, WebP and AVIF files smaller without sending them anywhere. Pick a preset or set the quality yourself, and see exactly how many bytes you saved.
Drop images here, or choose files
JPEG, PNG, WebP, AVIF, GIF and BMP. Up to 30 files, 25 MB each. Nothing is uploaded.

Compress
The saving shown is measured from the file that came out, never estimated. A file that would get bigger is reported as such and the original is offered instead.
How this works
Compression here means re-encoding the picture at a lower quality setting, on a canvas in this tab. The three presets are quality 78 (a good default for the web), quality 58 with the longest side capped at 1920 pixels (for when size matters more than detail), and quality 92 (for when it does not). WebP is the default output because it is smaller than JPEG at the same visual quality and keeps transparency.
The saving is measured, not estimated: the tool encodes the file, reads the size of what came out and compares it with what went in. When a file does not get smaller - which happens with images that were already well compressed, and with photographs converted to PNG - it says so and offers the original back instead of a worse file with a confident label.
Nothing is uploaded. Up to 30 images at 25 MB each can be queued, and each one is processed in turn with the page left responsive between them, so a long batch does not freeze the tab.
Website Performance and Core Web Vitals: Why They Matter for Business
Performance is not only a technical topic. Slow pages cost leads, harm SEO, and erode trust, and the things that fix them are usually small, specific, and boringly consistent.

SSR vs CSR vs SSG vs ISR: what to choose for SEO and performance
SSR, CSR, SSG and ISR differ mainly in where and when HTML is generated. For SEO, the key question is whether important content and metadata are available without waiting for client-side JavaScript. For performance, server cost, caching, JavaScript execution, hydration and freshness matter as well. In 2026, the best architecture is usually not one rendering mode for an entire application, but a strategy selected for each route or even each part of a route.

Core Web Vitals in 2026: LCP, INP and CLS in practice
Core Web Vitals in 2026 still consist of three metrics: LCP for loading the main content, INP for interaction responsiveness and CLS for layout stability. The scores alone do not tell you what to fix. Effective optimization requires separating real-user field data from lab tests, finding the actual LCP element, slow interaction or layout shift source, and then monitoring the result after deployment.
