About this Image Compressor

Compression re-encodes your image at a chosen quality using the browser's own encoder — no upload, no queue, no watermark. Quality 70–80% is usually visually indistinguishable from the original at a fraction of the size. Capping dimensions (e.g. 1920px for web use) often saves more than quality reduction alone. Batch-drop multiple files and download each result.

Frequently asked questions

Why did my PNG get bigger?
PNG is lossless — the quality slider does not apply. Convert photos to JPEG or WebP for real savings; keep PNG for graphics with sharp edges and transparency.
What quality should I choose?
75% is a sweet spot for photos on the web. Go 85%+ for portfolio images, 60% for thumbnails.
Are my photos uploaded?
No — everything happens in your browser via the HTML5 canvas. You can even use this tool offline once loaded.
