A WebP compressor produces smaller web images by using Google's WebP format, which combines lossy and lossless compression and transparency in one. WebP typically beats JPEG by a quarter to a third on photos and PNG by around a quarter on graphics at the same visible quality, which is why it has become the default for web performance. The sensible approach is to export WebP as a delivery format from a kept original, with a fallback for the rare browsers that cannot display it.

A PNG compressor reduces a PNG's file size mainly through colour quantisation, reducing millions of possible colours to a small, carefully chosen palette while keeping the alpha channel so transparency survives. PNG is lossless by nature, which makes it perfect for logos, icons, screenshots and text but heavy, and quantisation is what delivers large savings on those flat-colour graphics. Photographs saved as PNG compress poorly and almost always belong in JPG instead.

A JPG compressor reduces a JPG or JPEG photo's file size by re-encoding it with the format's lossy method, discarding the high-frequency detail the eye is least sensitive to. Because the loss is cumulative, the craft is to compress once from the original at a sensible quality, around 80 per cent, rather than re-saving repeatedly or pushing so low that blocking and banding appear. JPG is built for photographs; sharp graphics, text and anything needing transparency belong in a lossless format instead.

An image compressor reduces a file's size by re-encoding it more efficiently, either discarding data the eye barely notices (lossy, as in JPEG and WebP) or storing repeated information more compactly with no data loss (lossless, as in PNG). The practical skill is restraint: compress only as much as your size target or page-speed goal requires, since pushing past the natural sweet spot trades a lot of visible quality for very little extra saving. Choosing the right format for the job matters as much as the quality setting.

A questions explorer tool surfaces the questions people ask about a topic, grouped by type, so you can plan content that answers them directly. This matters because search is increasingly question-led, and featured snippets and AI overviews reward pages that give a clear, self-contained answer to a specific question. The strongest approach is to cover several question types and lead each answer with the point rather than burying it.

A keyword-rich domain tool generates name ideas around a keyword, but the modern value of a keyword in a domain is clarity and memorability rather than any ranking advantage, since search engines stopped rewarding exact-match domains long ago. The best names are short, easy to say and brandable, with the keyword woven in naturally rather than stuffed or hyphenated. Treat the output as ideas to check for availability and trademarks before registering.
