Web Image Optimizer
Get an image ready to publish. TryImager checks the format, the pixel dimensions against the width you actually display, and the compression density, then optimizes locally — no upload, no signup.
Your image is processed locally in your browser. It is never uploaded to our servers. No fixed size limit — we adapt to what your device can handle. Very large files may take longer or show a warning.
No display width given, so dimension recommendations are estimates based on a typical 1920 px layout.
Preparing images for a website
Publishing an image well is a short checklist: pick a modern format, ship it at about twice its display width, compress it lossily unless it needs to be pixel-exact, and keep transparency only where the design actually uses it. This page runs that checklist against a real file.
- Hero and banner images: usually the largest payload on a page — resize to layout width before compressing.
- Blog body images: rarely need more than 1200–1600 px of width.
- Product photos: benefit most from WebP, because they are numerous and often zoomable.
- Logos and icons: use SVG where you have it; otherwise WebP with transparency preserved.
Why oversized images cost more than bandwidth
A browser must download, decode and rasterise every image before it can paint. Decoding cost scales with pixel count, not file size, so a heavily compressed 24 megapixel photo can still stall a phone. Resizing addresses both halves of that problem at once, which is why automatic optimization resizes before it compresses.
Optimized images can help reduce file size and improve web performance. They are not a ranking trick, and no tool can promise a ranking outcome.
Batch thinking with a single-file tool
Run two or three representative images through the optimizer — a hero, a body image and a logo — and note the format and width it settles on for each. Those three settings usually generalise across an entire site's export pipeline.
Frequently asked questions
What width should I publish images at?
Roughly twice the widest CSS width the image is displayed at, capped at the image's own size. That covers high-density screens without shipping pixels nobody sees. Enter your display width above and the optimizer applies exactly that rule.
Should every image on my site be WebP?
For photographs and most graphics, yes — every current browser can display WebP. Keep SVG for vector artwork such as logos and icons, since it scales without extra bytes.
Does this help Core Web Vitals?
Smaller, correctly sized images reduce how many bytes must arrive and decode before a page finishes painting, which is one of several inputs to loading metrics such as Largest Contentful Paint. It is one factor among many, not a guarantee.
