How Image Compression Works
Compression shrinks a file by removing data the eye barely notices. Lossy formats like JPG and WebP discard fine detail and colour information in small blocks — you trade a little quality for a much smaller file. Lossless compression (PNG) keeps every pixel exact and saves space only by packing the data more efficiently, so the savings are smaller. The tool above lets you pull a quality slider and watch the file size fall in real time.
Choosing the Right Quality
For most web photos, 70–80% quality is the sweet spot: files drop by half or more while the difference stays invisible at normal viewing size. Push below 50% and you start to see blocky skies and haloed edges. Graphics with flat colour and sharp lines — logos, screenshots, charts — compress better and cleaner as PNG, while photographs almost always belong in JPG or WebP.
Why Smaller Images Matter
Image weight is the single biggest cause of slow pages. A homepage carrying 4 MB of photos can take seconds to load on mobile data, and Google factors that speed into search rankings through Core Web Vitals. Compressing every image before you upload — often cutting total page weight by 60–80% — is the easiest performance win most sites have.
Private, In-Browser Compression
The compressor processes your files locally, so nothing is uploaded and nothing is kept. Batch several at once, download, and you are done.
